Entity validation strange behaviour
I have a number of method validators against an entity.
The validators fire for incorrect data entered on the associated screen and once the data is fixed the user is presented with a second screen. All is fine so far ...
Until the user hits the back button to go back to the first screen. For some reason even though the user enters invalid data the method validators don't fire !!!. Very confusing.
Does anyone know of any reasons why this should occur ?
Many Thanks,
Richard
Hi,
I added a page-link to my second page as suggested. Using this method(instead of back button) causes the validation in the first screen to re-fire.
The previously entered values in the first screen are gone as its a new request.
I use code from your toystore to pre-create a record in the initializeModelForPage step. This fires when the link is clicked, and part of that code deletes the last entry from the entity cache. Therefore I'm not too surprised this works. As part of this project it has been stated that the users should be able to navigate through the browsers buttons, so I'm still abit stuck. Any suggestions ?
What i've done for now is to remove my validation from BC4J to my struts actions.
But because new values aren't recorded in the entity after a back button I also have to manually set the bindings for each screen field in my struts action.
I'm not an expert in the adf / struts frame work so I could just be missing something.
On a related point(assuming that i use entity validation) the following happens.
On my first screen I enter valid data , and then move to my second. I leave the screen in an invalid date before pressing the browsers back button. I then can't get past the first screen as it is still validating the errors in the second screen. Shay mention that I should be using a cancel button in the second screen to navigate back to the first. This is a public user application and I know that the back button will be pressed(its not good web design to remove/disable it anyway).
Any suggestions.
It seems that I can't get the ADF framework to work well with wizards and perhaps its best to just use struts for the validation and at the end of the wizard just call a database package to do the DML ?
Sorry but one last point - to do with the refresh button.
All my wizards use page forwards to move between screens and I know this can cause oddities with a refresh. What I have noticed is that when even refreshing the first page of my wizard(after leaving it in an invalid state) the screen doesn't change the errors are still there. I would have though the refresh would request a new refreshed page without the struts action errors. I even noticed that a refresh can cause a struts action related to a submit button to re-fire ? Why does this happen as it can cause a big mess.
Even re-entering the url in the same browser window doesn't cause the screen to properly refresh. The initializeModelForPage steps also do not fire when a refresh happens. I did notice that if I went to a different website and then re-entered the url that the page displayed more as expected and I think the initializeModelForPage step ran.
I'm sure alot of this is due to the fact that I don't really understand the framework, and thus would be grateful if you could explain why all the above happens. Is it what you would expect to happen ?
Many Thanks for your time and assistance.

How to stop attribute level validation when entity validator fails?
Hi,
Can you suggest any way to achieve the desired behaviour on the following scenario.
Table contains the following columns
1. Grade
2. Grade Rate
3. Status
Constraints:
1. Grade and Grade Rate together must be unique.
2. Grade and Grade Rate are mandatory fields.
Implementation:
1. Have Mandatory validator at attribute level for Grade and Grade Rate by default.
2. Alternate key is defined based on Grade and Grade Rate and added the same as Entity validator.
User operation scenario:
User adds a row in a table, entered 'GradeOne' as Grade, tabbed out and then entered '5 %' as Grade Rate (Existing row of the VO has a row with similar data already). When user try to navigate to other row, both validation at attribute level and entity level fires and gives the following error messages.
Error Msg 1. Grade and GradeRate should be unique.
Error Msg 2. Attribute GradeRate is required.
Expected behaviour:
I can understand the reason why ADF throws both the errors (coz it didn't consider the invalid value of GradeRate posted into attribute), but the error messages confuses the user. It would be great if he get only one error message in this scenario (i.e. Unique validation alone)
Question:
How can I restrict in such a way that only one error validation happens in a request (i.e. either attribute level or entity level or in a particular order}
Thanks in Advance.Hi,
the reason ADF does this is for performance. What if you create a custom error handler in the DataBindings.cpx file and use this to suppress all other errors?

Execution of entity validation multiple times (adf bc 10g)
Implementing entity method validators sometimes causes the validation (e.g. validateEntity method) to execute multiple times. We have figured out that this case occurs when we call method setAttribute programmatically when we implement business rules on the entity level. For example in many cases that we want to enforce dml operation execution, we override the method prepareForDML so that the framework works as follows:
• calls validateEntity, validates entity for the first time
• calls prepareForDML –> setAttribute this method invalidates the entity row
• calls validateEntity, validates entity for a second time
I can understand that sometimes multiple entity validation is necessary and important, there are cases though that this behaviour is not necessary and additionally it degrades performance especially when we utilize sql queries inside the validation (as it executes the queries multiple times).
Is there any workaround to avoid multiple execution of entity validation or enforce the validation to occur only once, for example after the prepareForDML method and not before?
Edited by: user647567 on 9 Σεπ 2010 6:58 πμHi there:
I don't think JDeveloper provides a switch to bypass the Entity Validation. Too much meddling. MVC model has those layers and advocates reducing unnecessary dependencies between layers. Entities and Views are both in Model layer though. But you can build a view without an Entity and vise versa you can have an Entity that doesn't have default views. So my understanding is the Entity Validation is quite necessary.
Though from View layer, on a jspx page, you can use command buttons and set their "immediate" property to "true" to bypass form validation temporarily and postpone it to form submission time.
My understanding for Entity validator is they should be light weighted. You properly should avoid SQL queries directly in them. Instead you should use EntityImpl or ViewObjImpl/ViewRowImpl instead of SQL queries directly in validator.
If you feel my answer helpful to you, please mark it so.
Thanks,

Strange behaviour whit custom JTextField and JToolTip
Hello everyone. I hope I'm writing in the right section and sorry if I did not search for this issue but I really don't know which keywords I should use.
I'm using NetBeans 6.1 on WinXP and JDK 1.6.0_07, I have a custom JTextField with regex validation: when you type something that don't mach regex it shows a JToolTip. This JToolTip should disappear when the text typed is finally correct, or when the textfield loses focus (see code below).
import java.awt.Component;
import java.awt.Dimension;
import java.awt.Point;
import javax.swing.JToolTip;
import javax.swing.Popup;
import javax.swing.PopupFactory;
public class MyJTextField extends javax.swing.JTextField implements FormComponent
private static Popup popUpToolTip;
private static PopupFactory popUpFactory = PopupFactory.getSharedInstance();
private boolean isValidated = false;
private String regEx = "a regex";
public MyJTextField()
this.addKeyListener(new java.awt.event.KeyAdapter()
public void keyReleased(java.awt.event.KeyEvent evt)
if(evt.getKeyCode()!=java.awt.event.KeyEvent.VK_ENTER)
validateComponent();
else if(evt.getKeyCode()==java.awt.event.KeyEvent.VK_ENTER)
if(isValidated)
((Component)evt.getSource()).transferFocus();
this.addFocusListener(new java.awt.event.FocusAdapter()
public void focusLost(java.awt.event.FocusEvent evt)
if(popUpToolTip!=null){popUpToolTip.hide();}
public void validateComponent()
if(text.matches(regex))
isValidated = true;
if(popUpToolTip!=null){popUpToolTip.hide();}
else
isValidated = false;
if(popUpToolTip!=null){popUpToolTip.hide();}
String error = "C'è un errore nella validazione di questo campo";
JToolTip toolTip = createToolTip();
toolTip.setTipText(error);
popUpToolTip = null;
popUpToolTip = popUpFactory.getPopup(
this,
toolTip,
getLocationOnScreen().x,
getLocationOnScreen().y - this.getPreferredSize().height -1
popUpToolTip.show();
}(I've cut it a bit, here's only the lines that involve JToolTip use)
I have many of them in a form, and when the first tooltip appears (on the first textfield I type in) it never disappears, while nex textfields work just fine.It seems the first tooltip appearing can't be overwritten or something similar. If I use this same component on any other NetBeans project, everithing works without issues.
I have some other custom components working the same way (JComboBox, JXDatePicker), and they had this "not disappearing tooltip" issue since I changed this
popUpToolTip = popUpFactory.getPopup(this, toolTip, getLocationOnScreen().x, getLocationOnScreen().y - this.getPreferredSize().height -1);
whit this
popUpToolTip = popUpFactory.getPopup(null, toolTip, getLocationOnScreen().x, getLocationOnScreen().y - this.getPreferredSize().height -1);
but if I try it on the JTextField all textfield's tooltips stay stuck there, not only the first one appeared (while other components still works fine).
This thing is really driving me crazy. Someone has an hint (or a link to another thread) which could explain this strange behaviour?
Thanks in advance.BoBear2681 wrote:
Note that an SSCCE wouldn't require you to post any proprietary code.Hmmm... well, I'll try again to reproduce the issue and post an SSCCE.

Maybe it's some interference between all the custom components I created, or maybe something else that apparently doesn't conern at all.

HELP: ADF-Error in Entity Validation - Validation fires twice
Hi there,
I have problems with the entity validation in JClient when I have more then one UI-Element that references to the same Data Control / Model Attribute within one panel.
E.g. I have a table where I display all customers. Above the table I show detail information with editable JTextFields for the customer I've selected in the table. When I change the name of a customer and leave the textfield, the new Value appears also in the table. Thats all ok.
The problem:
The entity validation fires twice in that example. E.g. when I insert 30 characters in the name field, but the corresponding database column only stores 20 characters, the
displayed exception appears twice. When I remove the textfields from the panel
and edit the values direct in the table, the validation only fires one time.
How can I avoid that behaviour? I have a lot of screens where it is important to show the list of objects in a table and let edit specific data via text fields.
That behaviour is also reproducable with the ADFJClientComponentDemo
(Jtree binding demo). If you insert more characters than allowed in the firstname field,
the Exception Message is shown twice.
Thanks for your help,
ClausHi Fred,
It's nice to know that somebody out there uses the same technology in a similar way.
Our L & F is also JGoodies based (we didn't use JGoodies forms).Yes, nice to know. We also only use L&F and not the JGoodies Layout Manager
(but if JDev 10.1.3 provides that layout manager maybe we use it for new panels).
In our JClient View project, we used very few try/catch blocks, mostly in our custom
Navigation bar class (with freeze row function).
How would you translate the following in 3tiers?
in the client class:
try {
// call a method in the model
catch (JboException je)
this.getPanelBinding().reportException(je);
}We don't use any try/catch-blocks to check for model-exceptions.
In our application a typical bootstrap code snipplet looks like that:
=======================================
//As classmember we have our own ErrorHandler:
protected HTOErrorHandler errorHandler = new HTOErrorHandler(true);
//some bootstrap code
BindingContext ctx = new BindingContext();
ctx.put(DataControlFactory.APP_PARAM_ENV_INFO, new JUEnvInfoProvider());
ctx.setLocaleContext(new DefLocaleContext(null));
//Set Custom Error Handler
ctx.setErrorHandler(errorHandler);
=======================================
Our Custom Error Handler Looks like this:
=======================================
public class HTOErrorHandler extends DCErrorHandlerImpl
boolean inReportException = false;
public HotErrorHandler(boolean setToThrow){
super(setToThrow);
public void reportException(DCBindingContainer bc, Exception ex){
disableAppendCodes(ex);
showPopup(ex);
super.reportException(bc, ex);
private void disableAppendCodes(Exception ex){
JboException jboEx = (JboException) ex;
String baseMsg = jboEx.getBaseMessage();
String detailMsg = jboEx.getDetailMessage();
String errorCode = jboEx.getErrorCode();
Locale defaultLoc = Locale.getDefault();
Object[] detailExceptions = jboEx.getDetails();
if ((detailExceptions != null) && (detailExceptions.length > 0)){
for (int z = 0, numEx = detailExceptions.length; z > numEx; z++){
disableAppendCodes((Exception) detailExceptions[z]);
public void showPopup(Exception ex){
DialogMessage dialog = new DialogMessage((JboException)ex);
dialog.setVisible(true);
=======================================
The DialogMessage is our own ModalDialog to show the ErrorMessages with
a userfriendly dialog (e.g. we show some error/warning/info-icon...)
Each time we throw a exception in a EntityObject the framework ensures that
the Message is shown in our own ModalDialog without using try/catch-blocks
and the this.getPanelBinding().reportException(je)-method;
We wrote our own ModalDialog because of L&F-reasons. But you said that
you use the Standard-Dialog. IMHO you must neverlethess use the setErrorHandler-Method
in 3-tier mode, but you needn't to write your own ErrorHandler, you can use the
JUErrorHandlerDlg....
The following line of code is generated by the ide when creating a default form:
app.getApplicationModule().fetchAttributeProperties(new String[] {"Test2View1"}, new >String[][] {{"Id2", "Name2", "Id3", "AttrTest"}}, null);
I read somewhere that when opening a panel, one should call that method for all used >properties in 3tiers mode only.Sorry, but we don't currently optimize something like that. For what reason
do you want to call that method explicit? We don't have a custom method for that.
I add tests in the validateEntity method and throw a JboException.
I suppose for 3tiers I will have to replace throw new JboException by ???? No. You don't have to replace that. The framework notifies your client via the registered ErrorHandler.
So when a mandatory field is empty, the framework displays an error when a commit
or navigation event is triggered in the nav bar and the user has always access to that
field.We want to override the default framework message with our own message. So we have
to throw the exception manually at some point in the entity object. And for that reason
we implemented a custom validation via MethodValidator, but the framework-validation fires
an exception BEFORE our custom validation is processed. Maybe you don't have that problem
because you use the default error messages. Do you use deferred Exceptions? We do so.
Did you try JClient 3tiers deployments over the Internet?Yes, we tried it via VPN/DSL to validate that our framework interface-usage works both in 2-tier and 3-tier.
After several attempts we were successfull, but the performance was poor.
PS Are you connected to skype? Unfortunately no because of firewall restrictions. We only have access to ICQ.

Strange behaviour in "Do - Until" statement
Hi,
I'm having a strange behaviour in a script I'm creating. The purpose of the script is to update some files in some folders. In the case that more folders need to use the script, I'm importing the folders name and path from a CSV file (much easier to read
it from there instead of hardcoding the folders in the code). As you can see, I add a number at the beginning of the folder's name, and then I let them choose which folder number do they want to update.
# Import from CSV File
$name = @()
$path = @()
$bkpPath = @()
Import-Csv $AppsFile |
ForEach-Object {
$name += $_.Name
$path += $_.Path
$bkpPath += $_.bkpPath
Write-Host "Choose the folder to update:"
Write-Host ""
$count = 1
foreach ($n in $name) {
Write-Host $count " - " $n
$count += 1
Do {$opt = read-host -prompt "Enter the option number"}
Until ($opt -lt $count -AND $opt -gt 0)
The problem appears when I started debuging the script, and try to input strange characters. The idea of the "Do - Until" statement, is that the user enters a loop until they choose a correct option. It works ok when it doesn't let you input letters,
or numbers outside the range I'm using.
The strange behaviour appears when I enter for example "0." (The important part is the DOT after the zero). There, it sends me to the last option in my CSV file. If I put "<number>.", it reads it as if it were "<number>".
And if I input a number out of range plus a final dot, it breaks my script (instead of just keep looping as it's supposed to).
Does anyone even understand the issue? =P It's really strange, I don't know if there is another way to limit the input...
Thanks,
Regards$opt is a string, and you're trying to compare it to numbers, which is probably going to give you headaches. I tend to write those types of loops like this:
$opt = $null
while ($true)
$string = read-host -prompt "Enter the option number"
if ([int]::TryParse($string, [ref]$opt) -and $opt -lt $count -and $opt -gt 0)
break
Simply because the validation can get kind of complex sometimes, and I think it's ugly to jam it in after an "until" statement, even though the end result is the same. -
Very strange behaviour of RGBImageFilter class
Hi!
I found very strange behaviour of RGBImageFilter class and problem is
that I need to solve that problem :/ So, situation is next:
I decided to use filtering process for collecting information about
image. So, I extended my own class from RGBImageFilter and overwrite
filterRGB( ... ) method ( everything is absolutely the same as in
documentation ) and also added my own code for 'no matter what'.
This code changes some class variable and my idea was to read those
variables after filtering process end, but... Suddenly I realized that
those variables, many times changed while filtering were performed
( I checked it ) after filtering gave the same value as in constructor!
The only one clue and idea about what happened is that class instance
were cloned and then executed, but thats not a functionality I was
searching. :/ I made some example of that 'effect'.
Image file name goes in command line.
Please pay attention on -3 value on exit: Filtering works, count growing
( just uncomment setPixels() method to see it ) but, but...

APEX Listener and EPG - strange behaviour
Hi
For some years, I've used EPG for APEX but have struggled with performance particularly as I can have up to 150 student developers using at any one time.
I do a fair amount of work using ORDImage and have successfully developed APEX applications to upload image files and display full-size and thumbnail images.
After upgrading to APEX 4.1 (from 4.0), I decided to install APEX Listener standalone.
Before I did so I checked that my applications still worked in 4.1 and they did.
However, just installing APEX Listener but not configuring it (yet) has meant that my image display in a report using a procedure based on wpg_docload.download_file( l_ordimage_image.source.localData ) no longer works in EPG - the images are not displayed.
Configuring APEX Listener and running the same application through that DOES display the images.
So this part of the application works under APEX Listener but not under EPG.
My application also allows users to upload images from APEX_APPLICATION_FILES using standard code. Under APEX Listener after uploading, I'm left with a blank page with a wwv_flow.accept URL although the image does indeed upload. Under EPG it works as expected and I get a success confirmation.
So this part of the application works under EPG but not under APEX Listener.
Has anyone else come across different behaviour depending on the mode of connection?
Thanks
Brian
[Oracle EE 11gR2, Windows Server 2008R2, APEX 4.1, APEX Listener 1.1.3]Hi Brian,
it sounds like you have both EPG and APEX Listener running on the same machine, so your problem might result from a port conflict. Note that both services use TCP port 8080 as default.
At least a port conflict would explain the strange behaviour in your case, some things working on one web server and some on the other.
Some parts of your initial post hint to that direction, e.g.
However, just installing APEX Listener but not configuring it (yet) has meant that my image display in a report using a procedure based on >wpg_docload.download_file( l_ordimage_image.source.localData ) no longer works in EPG - the images are not displayed.... because the APEX Listener only interfere with the EPG if it is at least running on the same machine as your database and furthermore, if it is unconfigured in terms of ist database connection, a port conflict might be the only way it could cause anything like that.
However, if you are sure that's not the issue, please check if you see any error in the APEX Listener's log for the following action you performed:
My application also allows users to upload images from APEX_APPLICATION_FILES using standard code. Under APEX Listener after uploading, I'm left with a blank >page with a wwv_flow.accept URL although the image does indeed uploadIf you actually see just a blank screen, something very bad must have happened and you should see some kind of stack trace there.
For further investigations, if necessary, it would be helpful to know how you deployed or started your APEX Listener and which JDK version you use.
For the moment, I still think the port conflict is my best guess.
You could avoid it by either changing the port for EPG (I'd not recommend that if you have other users still using it) or by changing the port for your APEX Listener.

Strange behaviour of Runtime.getRuntime().exec(command)
hello guys,
i wrote a program which executes some commands in commandline (actually tried multiple stuff.)
what did i try?
open "cmd.exe" manually (administrator)
type "echo %PROCESSOR_ARCHITECTURE%" and hit enter, which returns me
"AMD64"
type "java -version" and hit enter, which returns me:
"java version "1.6.0_10-beta"
Java(TM) SE Runtime Environment (build 1.6.0_10-beta-b25)
Java HotSpot(TM) 64-Bit Server VM (build 11.0-b12, mixed mode)"
type "reg query "HKLM\SOFTWARE\7-zip"" returns me:
HKEY_LOCAL_MACHINE\SOFTWARE\7-zip
Path REG_SZ C:\Program Files\7-Zip\
i wrote two functions to execute an command
1) simply calls exec and reads errin and stdout from the process started:
public static String execute(String command) {
String result = "";
try {
// Execute a command
Process child = Runtime.getRuntime().exec(command);
// Read from an input stream
InputStream in = child.getInputStream();
int c;
while ((c = in.read()) != -1) {
result += ((char) c);
in.close();
in = child.getErrorStream();
while ((c = in.read()) != -1) {
result += ((char) c);
in.close();
} catch (IOException e) {
return result;
}the second function allows me to send multiple commands to the cmd
public static String exec(String[] commands) {
String line;
String result = "";
OutputStream stdin = null;
InputStream stderr = null;
InputStream stdout = null;
// launch EXE and grab stdin/stdout and stderr
try {
Process process;
process = Runtime.getRuntime().exec("cmd.exe");
stdin = process.getOutputStream();
stderr = process.getErrorStream();
stdout = process.getInputStream();
// "write" the parms into stdin
for (int i = 0; i < commands.length; i++) {
line = commands[i] + "\n";
stdin.write(line.getBytes());
stdin.flush();
stdin.close();
// clean up if any output in stdout
BufferedReader brCleanUp = new BufferedReader(
new InputStreamReader(stdout));
while ((line = brCleanUp.readLine()) != null) {
result += line + "\n";
brCleanUp.close();
// clean up if any output in stderr
brCleanUp = new BufferedReader(new InputStreamReader(stderr));
while ((line = brCleanUp.readLine()) != null) {
result += "ERR: " + line + "\n";
brCleanUp.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
return result;
}so i try to execute the commands from above (yes, i am using \\ and \" in java)
(1) "echo %PROCESSOR_ARCHITECTURE%"
(2) "java -version"
(3) "reg query "HKLM\SOFTWARE\7-zip""
the first function returns me (note that ALL results are different from the stuff above!):
(1) "" <-- empty ?!
(2) java version "1.6.0_11"
Java(TM) SE Runtime Environment (build 1.6.0_11-b03)
Java HotSpot(TM) Client VM (build 11.0-b16, mixed mode, sharing)
(3) ERROR: The system was unable to find the specified registry key or value.
the second function returns me:
(1) x86 <-- huh? i have AMD64
(2) java version "1.6.0_11"
Java(TM) SE Runtime Environment (build 1.6.0_11-b03)
Java HotSpot(TM) Client VM (build 11.0-b16, mixed mode, sharing)
(3) ERROR: The system was unable to find the specified registry key or value.
horray! in this version the java version is correct! processor architecture is not empty but totally incorrect and the reg query is still err.
any help is wellcome
note: i only put stuff here, which returns me strange behaviour, most things are working correct with my functions (using the Runtime.getRuntime().exec(command); code)
note2: "reg query "HKLM\HARDWARE\DESCRIPTION\System\CentralProcessor\0" /t REG_SZ" IS working, so why are "some" queries result in ERR, while they are working if typed by hand in cmd.exe?ok, i exported a jar file and execute it from cmd:
java -jar myjar.jar
now the output is:
(1) "" if called by version 1, possible to retrieve by version 2 (no clue why!)
(2) "java version "1.6.0_10-beta"
Java(TM) SE Runtime Environment (build 1.6.0_10-beta-b25)
Java HotSpot(TM) 64-Bit Server VM (build 11.0-b12, mixed mode)"
(3) C:\Program Files\7-Zip\
so all three problems are gone! (but its a hard way, as i need both functions and parse a lot of text... :/ )
thanks for the tip, that eclipse changes variables (i really did not knew this one...) -

View Master mode strange behaviour with jpg files
Hy all,
I'm using Aperture, and I'm tweakin a lot the SW to discover all secrets ....
I'm really concerned about a strange behaviour of the SW in view mode.
If I open a jpg file, do not apply ANY modification, and apply the "show master" command (pressing M), there's a subtle behaviour :
*the images get sharper !!!!*
It behaves as if an "edge sharpening" was applied !!!!!!
With _RAW files this thing doesn't happen at all._
Even stranger, if I zoom to full definition (by pressing Z), and toggle between normal view and "show master" view, the immage remains the same !
The effect is not so evident with all images, but sometimes it is !!
Anyway, I expect not to have such kind of things with a professional SW.
With professional cameras and good quality files it's really annoying not to beeing sure what's the REAL content of the jpg image.
Has anyone noted this thing ? Is there a reasonable explanation ?
The only one I tried to figure out is the following : may be Aperture applies some kind of resampling algorithm with jpg files (bicubic, bilinear, etc).
May be this resampling is not applied with 100% magnification, as weel as with raw files.
But it's only my guessing. Now, I'm tweaking other viewers and other SW to understand what's the real jpg image stored in the file : the blurer one form normal view or the sharper one with "show master" mode.
I stress once again : of course, the jpg file I'm talking about have no settings at all, just imported and toggled with M button.
Thanks in advance.
Regards,
EnzoHy,
I'm afraid I'm not been clear.
The problem is this :
1) jpg image opened in normal view mode, no zoom, (no quick preview, of course) : image with a certain amount of blour
2) jpg image opened in show master mode, no zoom, (no quick previre, of course) : image SHARPER with respect with the previous.
No edit applied from import, so "show master" command shouln't apply any change in rendering, should it ?
The only thing I said on 100% view is that such difference (between normal mode e show mastermode) is not present with 100% magnification.
That was the issue.

Strange behaviour: two servers on the same port
Hi!
I hope this is the right section for this post. I need help about a strange behaviour involving a ServerSocket.
For my thesis I need to write a program that receives data from a pre-existing DSMS client, filters them and then sends them to a pre-existing DSMS server. And here is my problem: if I try to create a ServerSocket on the same port of the DSMS server, my program throws no exception, and the servers seem running on the same port. This is a behaviour that I'd like to avoid, but I cannot understand what the problem is. Can you help me?
The source code of the DSMS server can be found here (it's written in C++): http://infolab.stanford.edu/stream/code/stream-0.6.0.tar.gz
The source code of my server class, instead, is this one:
import java.io.*;
import java.net.*;
public class ThreadGenerator {
private ServerSocket server;
public void connect(String servPort, String cHost, String cPort) {
try {
server = new ServerSocket(servPort);
System.out.println("SERVER running on port "+servPort);
} catch (BindException e) {
System.out.println("Address already in use!");
} catch (Exception e) {
System.err.println(e);
try {
while(true){
Socket client = server.accept();
StreamThread T = new StreamThread(client, cHost, cPort);
T.start();
} catch (EOFException e) {
System.out.println("Server closed connection!");
} catch (Exception e) {
System.err.println(e);
}I'm programming on Mac OSX Tiger, with Java 1.5.0.
Thanks in advance for your help.The problem is still happening to me, I tried in this very moment. The code I'm using is the one I posted, and the second server is the one that I linked. I don't think there's anything else to add.
If you're sure that the problem is not in my code, then it means that it is in the linked server, which partially solves the problem. But I'd like to know, if it's possibile, if there is any other way to check if the port is already in use. -
Cursor shows strange behaviour in 10.9.5
HI,
I'm using a 15" MBPr late 2013, i7, 16 GB RAM, 1 TB SSD, running on 10.9.5. Lately I registered a very strange behaviour of the cursor when using the built in trackpad. If hovering over one of the symbols in the bar at the upper right corner of the screen and then moving the cursor downward, the menu of the symbol on the right of the cursor pops up (not the one the cursor ist pointing on).
For example: the symbol for WiFi is located left from the one regulating the volume. When hovering over WiFi and moving downwards to activate/deactivate it, the volume-controle pops up ! If I want to use the WiFi, I have to hover over the symbol for bluetooth-connectivity instead....
Any idea whats happening here ?
Help is very much appreciated !
MIchaelOK, found the solution by myself. The reason seemed to be related to the resolution of the display. Changed it to another one (no matter which one), waited for the display to change and the changed the res back to optimal for display.
The cursor now works fine and exactly....

Windows 8.1 Enterprise Evaluation- Strange behaviour of network adapter
Hello there are discussions and questions around this community about network adapter dropping connection while system is running. But I have found unique problem with my network adapter driver.
I have tried to state my problem as clearly as possible. Please ask if any detail is required.
My network status shows no access on following occasions:
1. On alternate system wakeups.
eg:
a. System boots up
Internet accessible
no problem
b. I put system to sleep(first time) and wake it up
No access to internet !!!
When I check in network and sharing center not even adapter shows in disabled status.(See video from the link given below).
c. Without restarting system or without installing network adapter again, I put system to sleep again and wake it up (2nd time).
Internet accessible
d. I put system to sleep for (3rd time) and wakes it up.
No access to internet!!
If I put system to sleep again and wake it up definitly I get network access.
2. If I switch off the modem before windows shutdown completely or in the process of shutdown, next time when I boot system, even though the modem is switched on before booting the system, No internet access tooltip will be shown on network
sysbol.
Another strange behaviour is on no internet access status, I start installing adapter, and it loads required files and prompt me to click "next" and "click" install.
But the thing is before I go to "next" button, I will get network access as shown in this link
http://youtu.be/sPlXVEiYBeo. Ignore virtualbox adapter. Same behaviour was there when there is no vbox adapter. Same was happening in Windows 8 Pro, but not in windows 7, so that there is no H/W problem I think.
Any idea on how to fix this or any alternate solution ?Hi,
Firstly, access your network adapter official website to get the proper driver applied to your system.
Then going to Control Panel > Device Manager, right click your adapter > Properties. Under the Power Management tab, make sure "Allow the computer to turn off this device to save power" checkbox unchecked.
If it still persists, try to disable "fast startup" as below steps:
1.In Control Panel, open the Power Options item.
2.Click the Choose what the power buttons do link.
3.Clear the Turn on fast startup (recommended) check box.
4.Click Save Settings.

Strange behaviour from new 2012R2 in old domain
Hi all,
At work (education level), I'm starting to take charge of windows admin, so beiing a noob admin I'm finding strange behaviours that I hope you can help me solve them all :-)
We've one (big) domain with about 5000 computers (workers and students all together), and around 50000 users (again, workers and students all together) setup like this:
DC-DOMAIN-1:
Windows Server 2008R2
Shares NETLOGON and SYSVOL
DC-DOMAIN-2:
Windows Server 2003 R2 x64
Shares CertEnroll, NETLOGON, SMSLOGON, SYSVOL
Checking RootDSE, I see 'domainControllerFunctionaly is Windows 2003' (DC-DOMAIN-2)
So, with this setup, I've noticed these strange behaviours, hope list isn't too big (guess there will be more behaviours but these seemed too odd):
1) On DC-DOMAIN-2, WinServer 2003 eventlog, inside 'Directory Service', I found this warning event ID 1083 (Source NTDS Replication):
Active Directory could not update the following object with changes received from the domain controller at the following network address because Active Directory was busy processing information.
Object:CN=<an user name>, CN=Users, DC=DOMAIN
Usually followed by an information event (eventid 1955) which says:
ctive Directory encountered a write conflict when applying replicated changes to the following object.
Object:
<SAME USER OBJECT THAN PREVIOUS EVENT ID>
Time in seconds:
0
Event log entries preceding this entry will indicate whether or not the update was accepted.
A write conflict can be caused by simultaneous changes to the same object or simultaneous changes to other objects that have attributes referencing this object. This commonly occurs when the object represents a large group with many members, and the functional level of the forest is set to Windows 2000. This conflict triggered additional retries of the update. If the system appears slow, it could be because replication of these changes is occurring.
User Action
Use smaller groups for this operation or raise the functional level to Windows Server 2003.
And having as result that user being blocked in domain.
2) I've added a new print server based on Windows Server 2012R2 (running inside an updated ESX 5.5 with VMXNET3 ethernet adapter as recommended by vmware), and seen in the event viewer these warnings/errors:
At System log:
Error Event ID 5783, Source NETLOGON:
The session setup to the Windows NT or Windows 2000 Domain Controller \\DC-DOMAIN-2.fulldns.name for the domain DOMAIN is not responsive. The current RPC call from Netlogon on \\PRINTSERVER to \\DC-DOMAIN-2.fulldns.name has been cancelled.
I've seen Event ID 5783 with DC-DOMAIN-1 too....
Error Event ID 5719, Source NETLOGON:
This computer was not able to set up a secure session with a domain controller in domain DOMAIN due to the following:
The remote procedure call failed and did not execute.
This may lead to authentication problems. Make sure that
this computer is connected to the network. If the problem persists, please contact your domain administrator.
ADDITIONAL INFO:
If this computer is a domain controller for the specified domain, it sets up the secure session to the primary domain controller emulator in the specified domain. Otherwise, this computer sets up the secure session to any domain controller in the specified domain.
At Microsoft-Windows-TerminalServices-RemoteConnectinoManager/Admin found also this warning:
Warning Event ID 20499 Source TerminalServices-RemoteConnectionManager:
Remote Desktop Services has taken too long to load the user configuration from server \\DC-DOMAIN-2.fulldns.name for user administrator
3) If I try Group Policy Modeling on DC-DOMAIN-1 (server 2008R2), everything works fine, no matter if I try it against DC-DOMAIN-1 or DC-DOMAIN-2, but if I try this from the Server 2012R2 (the one from point 2), I get this:
Simulation against DC-DOMAIN-2: Gets executed, but all GPO show as inaccessible, empty or disabled.
Simulation against DC-DOMAIN-1: Sometimes it gets executed as DC-DOMAIN-2, sometimes I get an error saying query can't be executed.
4) From server 2012R2, I usually manage printing GPO. If I click on the domain root (GPMC, forest, Domains, DOMAIN-NAME-ROOT) right pane, I get a pop up saying:
'A processing error ocurred collecting data using this base domain controller. Please change the base domain controller and try again'
After closing popup, right pane says something like 'DC-DOMAIN-2.fulldns.name' is the baseline domain controller for this domain.
No infrastructure Status information exists for this domain.
Click the Detect Now button below to gather infrastructure status from all of the domain controllers in this domain.
Pressing 'Detect Now' does nothing, and trying to select New Baseline DC shows again same pop up than before.
5) Last, but not least, I've feeling that GPO takes too much to apply. I've found scenarios in which even after executing 'gpupdate /force' correctly on client computer either local or domain admin, I can't see the new changes (gpresult says it has been
updated though). But couldn't find anything on eventlog that informs about problems with GPOs...
For all these strange behaviours I've noticed in last month that I started checking things as sys admin, I believe domain is damaged, or something is wrong there (not just my new server 2012R2, even if it's running inside an ESX, blehh), so please, any hint
on what to check, what to change, what to fix, would be highly appreciated.
Thanks in advance.Hi Paul,
Honestly, I'm still trying to figure out all broken things reported by tests :( Guess Jesper's suggestion about adding a new 2008 DC to get rid of 2003 and start checking again after that may be best option.
I'll try to summarize list of things I believe are wrong:
running
DCDIAG /V /C /D /E /s:yourdcname > c:\dcdiag.log for every DC, shows different errors. They show things such as:
another domain running here (not administered by us, only relationship is that our users are shared with that domain, nothing else) appear when Printing out pDsInfo (as if they were DC of our domain too, but they do not even share RootDomain). Guess it
may be for a bug old sys admin had when clonning from his 2008R2 template, that forgot to change SID... I already noticed 1 year ago our print server shared SID with those DC, guess there may be more servers sharing SID too :-(
Within Starting test: Replications, I see few messages at Replication Latency Check, such as the one for CN=Schema, CN=Configuration, DC=<ourdomain>:
Latency information for 35 entries in the vector were ignored.
35 were retired Invocations. 0 were either: read-only replicas and are not verifiably latent, or dc's no longer replicating this nc. 0 had no latency information (Win2K DC)
On Services test, I see an
Invalid service type: RpcSs on DC-DOMAIN-3, current value
WIN32_OWN_PROCESS, expected value WIN32_SHARE_PROCESS
On SystemLog, I see LOTS of warnings/errors such as:
A warning event occurred. EventID: 0x80000002
Time Generated: 07/28/2014 08:21:54
(Event String (event log = System) could not be retrieved, error
0x503)
An error event occurred. EventID: 0xC0000003
Time Generated: 07/28/2014 08:22:18
(Event String (event log = System) could not be retrieved, error
0x3afc)
Missing entries on DNS (we've a static DNS)
netdiag.exe /v > c:\netdiag.log Showed again DNS problems such as our primary DNS pointing to all DC, secondary
DNS pointing just to DC with FSMO roles,...
repadmin.exe /showrepl * /verbose /all /intersite > c:\repl.txt Gave no errors, now I must check in detail
if every replica is correct
And finally,
dnslint /ad /s "ip address of your dc" gave more DNS problems:
One or more DNS servers may not be authoritative for the domain
One or more DNS servers did not respond to UDP queries
One or more zone files may have expired
SOA record data was unavailable and/or missing on one or more DNS servers
Sumarizing, guess it will be better to fix DNS problems, promote new 2008R2 DC to get rid of 2003 one, promote domain to 2008 too, check again for messages and relationship with other domain, and then come back here for support if needed
EDIT: Almost forgot to talk about SYSVOL folder. As said before, there are 426 GPO folders inside Policies. Of them, 375 have an inetres.adm files in it (smallest one 1398 KB, almost all of them 2307 or 2707 kb)....
