Forum "Handle" problem
Hello,
I have a problem with my forum handle. It was Joel_C this morning but appears to have reverted to a numeric equivalent. When you attempt to edit your handle in the profile editor, the handle appears as it ought to.
Is anyone else having this trouble?
It's a known problem that happens occasionally.
The loss is not permanent, your handle will return once the necessary server/service is back to normal.
hsawwan is being 494875.BluShadow is being 452534. is about that problem, for example.

Delicate ProgressMonitor/ event handling problem
Hi,
I have a delicate ProgressMonitor / event handling problem.
There exists some solution on similiar problems here in the forums, but no solution to my special problem, hope anybody can help me out.
I have a rather big project, an applet, that I've written a separate JarLoader class that will load specific jar's if the ClassLoader encounter a unloaded class, all ok so far.
But, during loading, I would like to display a ProgressBar. And here is the problem. If my custom ClassLoader intercepts a findClass -request that needs to load the class from a jar from a normal thread, this is no problem, but if the ClassLoader intercepts a findClass that needs loading a jar when inside the EventQueue -thread, this is becomming tricky!
The catch is that an event posted on the EventQueue finally needs a class that needs to be loaded, but I cannot dispatch a thread to do this and end that particular event before the class itself is loaded.
So how do I hold the current EventQueue -event needing a jar -load, Pop up a ProgressBar, then process events in the EventQueue to display the ProgressBar and update repaints in it? then return from the event that now have loaded needed class-files.
I've tried a tip described earlier in the forums by trying to handle events with this code when loading the Jar:
/** process any waiting events - use during long operations
* to update UI */
static public void doEvents() {
// need to derive from EventQueue otherwise
// don't have access to protected method dispatchEvent()
class EvtQueue extends java.awt.EventQueue {
public void doEvents() {
Toolkit toolKit = Toolkit.getDefaultToolkit();
EventQueue evtQueue = toolKit.getSystemEventQueue();
// loop whilst there are events to process
while (evtQueue.peekEvent() != null) {
try {
// if there are then get the event
AWTEvent evt = evtQueue.getNextEvent();
// and dispatch it
super.dispatchEvent(evt);
catch (java.lang.InterruptedException e) {
// if we get an exception in getNextEvent()
// do nothing
// create an instance of our new class
EvtQueue evtQueue = new EvtQueue();
// and call the doEvents method to process the events.
evtQueue.doEvents();
}Then, the loader checks
java.awt.EventQueue.isDispatchThread()to see if its' inside the eventqueue, and runs doEvents after updating the ProgressMonitor with new setProgress and setNote values.
More precise;
The loader is loading the jar like this:
(this is pseudo code, not really usable, but outlines the vital parts)
public void load() {
monitor = new ProgressMonitor(null, "Loading " + jarName, ""+jarSize + " bytes", 0, jarSize);
monitor.setMillisToDecideToPopup(0);
monitor.setMillisToPopup(0);
// reading jar info code here ...
JarEntry zip = input.getNextJarEntry();
for (;zip != null;) {
// misc file handling here... total = current bytes read
monitor.setProgress(total);
monitor.setNote(note);
if (java.awt.EventQueue.isDispatchThread()) {
doEvents();
zip = input.getNextJarEntry();
monitor.close();
}When debugging doEvents(), there is never any events pending in peekEvents(), even if I tries to put a invokeLater() to run the setProgress on the monitor, why? If it had worked, the doEvents() code would have saved my day...
So, this is where I'm totally stuck...Just want to describe how I did this using spin from http://spin.sourceforge.net
This example is not pretty, but it can probably help others understanding spin. Cancelling the ProgressMonitor is not implemented, but can easily be done by checking on ProgressMonitor.isCanceled() in
the implementation code.
First, I create a bean for displaying and run a ProgressMonitor:
Spin requires an Interface and an Implementation, but that's just nice programming practice :-)
import java.util.*;
public interface ProgressMonitorBean {
public void start(); // start spinning
public void cancel(); // cancel
public int getProgress(); // get the current progress value
public void setProgress(int progress); // set progress value
public void addObserver(Observer observer); // observer on the progressValue
}Then, I created the implementation:
import java.util.*;
import javax.swing.ProgressMonitor;
import java.awt.*;
public class ProgressMonitorBeanImpl extends Observable implements ProgressMonitorBean {
private ProgressMonitor monitor;
private boolean cancelled;
private int progress = 0;
private int currentprogress = 0;
public ProgressMonitorBeanImpl(Component parent, Object message, String note, int min, int max) {
monitor = new ProgressMonitor(parent, message, note, min, max);
monitor.setMillisToDecideToPopup(0);
monitor.setMillisToPopup(0);
public void cancel() {
monitor.close();
public void start() {
cancelled = false;
progress = 0;
currentprogress = 0;
while (progress < m_cMonitor.getMaximum()) {
try {
synchronized (this) {
wait(50); // Spinning with 50 ms delay
if (progress != currentprogress) { // change only when different from previous value
setChanged();
notifyObservers(new Integer(progress));
monitor.setProgress(progress);
currentprogress = progress;
} catch (InterruptedException ex) {
// ignore
if (cancelled) {
break;
public int getProgress() {
return progress;
public void setProgress(int progress) {
this.progress = progress;
}in my class/jarloader code, something like this is done:
public void load() {
ProgressMonitorBean monitor = (ProgressMonitorBean)Spin.off(new ProgressMonitorBeanImpl(null, "Loading " + url,"", 0, jarSize));
Thread t = new Thread() {
public void run() {
JarEntry zip = input.getNextJarEntry();
for (;zip != null;) {
// misc file handling here... progress = current bytes read
monitor.setProgress(progress);
t.start(); // fire off loadin into own thread to do time consuming work
monitor.start(); // this will spin events on monitor and block until progress = max
monitor.cancel(); // Just make sure ProgressMonitor is closed
}The beautiful thing here is that Spin is taking care of weither the load() is inside the dispatch thread or not, making the code much simpler and cleaner to understand.
The ProgressMonitorBeanImplementation could been made much nicer and more complete, but I was in a hurry to check if it worked out. And it did! This will be applied on a lot of gui -components that blocks the event-queue in our project, making it much more responsive.
Hope this will help others in similiar situations! Thanks again svenmeier for pointing me to the spin -project. -
Has anyone in this Forum had problems with installing and running Adobe apps on the new MacPro?
I have been trying to install Photoshop CS6 & CC and Acrobat Pro XI on my Mac Pro (late 2013). I keep getting a 'configuration' error message and wondered if the problem was wide spread.
TIA,
JerryThanks, Martin.
Good to hear someone has had success. The lack of it here is frustrating and depressing.

Exception Handling Problem In BPM
All
I am facing an exception handling problem I am using BPM and , I have caught exception in the transformation step but when there is any data problem in that mapping(mentioned in the transformation)
it is not throwing the exception . is there any option to collect these type of system exception in the bpm and give a alert thru mail
is there any way to collect these type of exception happened in the BPE and raise alert thru generic alert
Thanks
JayaramanHi Jayaraman,
When you say there is any data problem, does that fail the message mapping that you have defined?
If the message mapping used in the tranformation fails, it should raise an exception in the BPM.
Did you test the message mapping using the payload and see if it really fails or not?

GUI event handling problems appear in 1.4.1 vs. 1.3.1?
Hi,
Has anyone else experienced strange event handling problems when migrating from 1.3.1 to 1.4.1? My GUI applications that make use of Swing's AbstractTableModel suddenly don't track mouse and selection events quickly anymore. Formerly zippy tables are now very unresponsive to user interactions.
I've run the code through JProbe under both 1.3 and 1.4 and see no differences in the profiles, yet the 1.4.1 version is virtually unusable. I had hoped that JProbe would show me that some low-level event-handling related or drawing method was getting wailed on in 1.4, but that was not the case.
My only guess is that the existing installation of 1.3.1 is interfering with the 1.4.1 installation is some way. Any thoughts on that before I trash the 1.3.1 installation (which I'm slightly reluctant to do)?
My platform is Windows XP Pro on a 2GHz P4 with 1GB RAM.
Here's my test case:
import javax.swing.table.AbstractTableModel;
import javax.swing.*;
import java.awt.*;
public class VerySimpleTableModel extends AbstractTableModel
private int d_rows = 0;
private int d_cols = 0;
private String[][] d_data = null;
public VerySimpleTableModel(int rows,int cols)
System.err.println("Creating table of size [" + rows + "," + cols +
d_rows = rows;
d_cols = cols;
d_data = new String[d_rows][d_cols];
int r = 0;
while (r < d_rows){
int c = 0;
while (c < d_cols){
d_data[r][c] = new String("[" + r + "," + c + "]");
c++;
r++;
System.err.println("Done.");
public int getRowCount()
return d_rows;
public int getColumnCount()
return d_cols;
public Object getValueAt(int rowIndex, int columnIndex)
return d_data[rowIndex][columnIndex];
public static void main(String[] args)
System.err.println( "1.4..." );
JFrame window = new JFrame();
window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JPanel panel = new JPanel();
Dimension size = new Dimension(500,500);
panel.setMinimumSize(size);
panel.setMaximumSize(size);
JTable table = new JTable(new VerySimpleTableModel(40,5));
panel.add(table);
window.getContentPane().add(panel);
window.setSize(new Dimension(600,800));
window.validate();
window.setVisible(true);
Thanks in advance!!
- DeanHi,
I've fixed the problem by upgrading to 1.4.1_02. I was on 1.4.1_01.
I did further narrow down the symptoms more. It seemed the further the distance from the previous mouse click, the longer it would take for the table row to highlight. So, clicking on row 1, then 2, was much faster than clicking on row 1, then row 40.
If no one else has seen this problem -- good! I wouldn't wish the tremendous waste of time I've had on anyone!

Labview slider event handling problems - revisited
This topic asked a question that was very close to a problem I am having:
Labview slider event handling problems
That is, how do I, using an event structure and/or other means, only read out the value of a slider control after the value change is finalized?
The extra constraint I'd like to place on this, which I believe will invalidate the answer given in the thread above, is that my slider control also has a digital display which can also be used to change the value without ever using the mouse. I cannot look for a value change followed by a mouse-up event if the mouse was not used to change the value.
Any ideas how this might be accomplished? FWIW, I am using LabVIEW 7.0Each and every incremental value-change event generated by the movement of the slider is still detected and queued up for use by the event structure and the event structure loop wades through them all before it's done.
I have come up the attached "fix" (LV v7.0) for this problem. While it is not as clean a solution as I had hoped it would be, it's the best I can manage given what LabVIEW offers me to work with and it does work in the situation where I need to use it.
Now, within the Finalize Slider Events subVI, I'm keeping track of the most-recent values seen by the subVI, checking to see if they have changed, and reporting out that fact. That gives me a Changed/Not-Changed bit within the event case that I can use to control what code then gets executed. If the event case is just playing catch-up to the real value of the control, I can now see that fact and ignore it.
In this version I've also dumped the variant output and limited the VI to using DBL values. I decided it added complication to something that was too complicated already and I wanted the output terminals for other purposes anyway (reporting of the correct "OldVal" of the control).Message Edited by Warren Massey on 04-28-2005 03:56 AM

My Oracle Forums Handle Name Changed without my notice!!!
Hello Oracle Forums Moderators,
I joined Oracle Forums 04/04/08 with and email address (1). I decided to change my email address and handle names, so my forums handle name is cutedba and my email address is (2). I already had like 8 posts in oracle forums. Today when I logged to oracle forums I found my handle name is user8722709 and my posts resets to only one post (with this thread, it will become two posts).
and my joining date became 08/19/09.
I went to the control panel and edited the profile and handle name to cutedba. I received the following message:
"The handle you are trying to update is already being used, please identify any other value and retry."
and I logged as my new email address (2) as usual. Please fix this for me. Because I am the cutedba in Oracle Forums.
I also want to mark one of the threads I created earlier as answered but I can't the forum thinks I am not the author of that thread:
How to install multiple oracle homes in oralce 9i on unix
Thank you and best regards,
cutedbaOk, let's see if I understand this clearly (cos if I don't then I'm sure the site admin won't)...
1. You created an account (let's call it "Account 1")...
Acount 1:-
Email Address: [email protected]
Forum Notifications Email: [email protected]
Handle: {default}
2. You created a second account (let's call it "Account 2")...
Account 2:-
Email Address: [email protected]
Forum Notifications Email: [email protected]
Handle: {default}
3. You modifed Account 1 to change the Forum Notifications Email and the handle:
Account 1:-
Email Address: [email protected]
Forum Notifications Email: [email protected]
Handle: cutedba
That's right.
all my forum participation were updated including post numbers.
What was updated? All you did was change your notification email and your handle on Account 1?You are right.
I also successfully login using email id (B) with the password, no issues.Yes, I dedicated an email account for oracle stuff and I used it to create an oracle account (Account B) because I couldn't delete/disable Account A from oracle.
>
4/ submitted a new thread in oracle forum as in the link I mentioned earlier.I don't see that has any relevance.correct!
5/ when I visited back Oracle Forums Today, I saw that my post count reset to 1 (last reply) and the system identified me as a different user (user8722709) than cutedba. I went to the Control Panel and Modified the Name Handle for forums back to cutedba . I received the message mentioned earlier.Which account did you log on as?Account B
It seams that Oracle forums end me up with two identities!!But you created two, so there will be two. ?:|Because oracle will not delete/disable account A
Please I need you to help on fixing this issue.I'm just a user of OTN like yourself, I can't fix it, I'm just trying to help ascertain exactly what you've done.I understand, thank you for help and make this issue clearer even to me ;-)
One more thing, I logged in to oracle forums using email (A) and my profile cutedba is there.Brilliant, that's what I'd expect.
I went to the Control panel and found the Username is still with email (A) but the forums email is with email and (B).Exactly, that's also what I'd expect.
But why still the the username did not changed and my profile is not updated yet?On which account?Account A
Occasionally, if OTN have been doing upgrades or such things, I believe the forums will move across to the failover servers, so sometimes changes to profiles may not be picked up or transferred back to the main servers. However, you said you'd logged in with Account 1 and it said cutedba on it.
I think it is the same bug in the forums.
I feel this too.
I wish if OTN has the ability to allow users to delete account that are no longer necessary, like my case here. Account A is no longer necessary for me but if switched the handle names between account A and B, I still can't get the credits and links for Account B profile.
How to report OTN bugs?
Regards,
Cutedba -
As you can see if you click to view my profile my forum handel is "Ivan Ćurić". First and last letter of my surname is ć or in unicode "c with acute" (uppercase: U+0106, lowercase: U+0107). Due to some problems in your forum software my surname is displayed as "Ivan Ćuri&..." - last letter of my surname is replaced with "&" sign.
I supose it is a bug in character counting and conversion from unicode to HTML entities.
Please, will you consider repairing this?It's a known problem that happens occasionally.
The loss is not permanent, your handle will return once the necessary server/service is back to normal.

Request.getParameter(): special character handling problem
Hello, there:
This should be an easy question for the gurus in here.
I use a string attached to the url as the parameter string, which includes spaces. the system automatically converts them to %20, but when I receive them in my servlet using request.getParameter, a special character, Â appears; I couldn't proceed with it.
I suppose this is a common problem but seems that I didn't find topics about it on this forum.
So anyone can help? Any encoder/decoder APIs to handle it?
Thanks a lot,
Swayhi,
escape can solve ur problem
use js function to submit form like
function subForm()
var any_spcl_value ="kdfhjdf$%@#$% 2FGSFG @%@#%@# V";
mainForm.action = "index.jsp?value="+ escape(any_spcl_value);
mainForm.submit();
and use request.getParameter("value");
u ll get kdfhjdf$%@#$% 2FGSFG @%@#%@# V as it is.

Oracle forums: Handle name after changing email
Hi All,
After changing my email, handle name on my old posts were changed to "974972" and all those old posts are not listed under my new accounts/handle name any more.
New posts work fine. Any help would be appreciated!
Thanks!

You would need to contact otnfeedback at oracle.com via email to ask them to correct it, though you've probably picked a bad time to change your email, considering the forums are due to be upgraded this weekend to new software, and correcting that issue is something that is usually picked up by admin within about 1 week, though I imagine they're a tad busy at the minute with the pending upgrade.is this issue will be included with Forum upgrade ?Your guess is as good as mine. -
Noticed some issues with how NI DNET card handles problems
We have
noticed 2 issues with using the PXI NI-DNET (PXI-8461) card and Labview (8.5).
1. The scanner doesn’t recover from a lost of
DNET power
- With network
work up and everything scanning
- The Dnet
DC power is turned off and then turned back on
- All nodes are rest from the power cycle which
is common
- However,
when we try to scan the network again, Labview faults with can’t initialize card
I believe
- No nodes
restart
The DNET
card seems to not be monitoring the network DC power and releasing the handles
and/or trying to rescan the attached nodes.
Work
around: Restart the PXI or in Max, remove and reinstall DNET card
The work around are not a good solution. Is there another solution and why isn't the card restarting.
2. When Labview locks up, the DNET card keeps
scanning. When this happens the last
setpoints are still being sent. This can
be a problem if a heating is being controlled.
No work around
Is there any watch dog for this issue?Howdy Olaje,
I think I've found a solution for your first question. Take a look at this Discussion Forum and see if it does the trick. However, I need a bit more information about your second question. I'm curious about the specifics of how LabVIEW "locks up". Is this a permanent crash or does it just freeze for a few minutes while control is transfered to another process? Also, what is the context of the lock up? Thanks for answering these follow up questions, I look forward to the response!

BSP extension "download" - event handling problem
Folks,
First of all, I apologize if the answer is already out there, but I spent quite some time to find the solution for my problem but finally gave up:
I implemented the Download extension from Brian's and Tom's book. Since I am using an MVC based app, I put the event handling in the DO_HANDLE_EVENT of a controller instead of the OnInputProcessing event of a page. Here's how my app is designed:
I have a main controller that has an execute button to trigger a data selection based on some selection criteria. The result of this selection is displayed by means of a subcontroller with tableviews that are wrapped into my zdownload extension. Everything works fine: I make my selections, execute the app through the button of the main controller and get my result shown in the tableviews. I push the download icon, select my file format (XLS, HTML etc), get the dialog to choose whether to download or to display the file, perfect!
But now after I processed the download successfully - if I click the execute button in the main controller again, I still get the download dialog. It looks like the created event for the download does not get cleared. As I mentioned, I searched through SDN, but all I found were referrals to the call of DISPATCH_INPUT( ) in DO_REQUEST of the main controller, but unfortunately this one is already implemented.
Any ideas?
Thanks,
GuentherThere is an attribute of the download extension called display_url. You pass a value to the extension telling it what cached URL contains the binary content for your download. if this display_url attribute has a value assigned to it, then the element will render an iFrame to call the URl. However if the display_url attribute is empty, it won't render the iFrame. I suspect that you have a stateful application and after your download event you aren't clearing whatever field that you pass into the display_url attribute.

Hi,
I'm having problems with a event handler that I'm trying to create.
I currently have 2 event handlers, one of which needs to only happen when Shift + a key is pressed. I currently have:
function keypressedHandler(event:KeyboardEvent):void { if ((event.shiftKey) + (event.keyCode == 81)) { //something would happen } }
So my question is how can I get the shift function to work? It doesn't matter if it isn't shift but Alt or Ctrl would be the alternatives.
Any help would be great,
Thanks,You need the ampersand (&) instead of the plus sign to use the logical AND:
stage.addEventListener( KeyboardEvent.KEY_DOWN, keypressedHandler )
function keypressedHandler(event:KeyboardEvent):void
if ((event.shiftKey) && (event.keyCode == 65))
//something would happen
trace( "shift and 65" ) -

ColdFusion.Ajax.submitForm error handler problem with AppleWebKit-based browsers
All-
When using an AppleWebKit-based browser (i.e. Safari or
Chrome), the
message argument of the Coldfusion.Ajax.submitForm error
handler always contains the string "OK", regardless of what error
was cfthrown by my CFM form handler.
Recall that the signature for the error handler is this:
MyFormErrorHandler = function( code, message )
In other browsers (i.e. IE or Firefox), the
message argument of the error handler properly contains the
message that was cfthrown by my form handler.
Can anyone offer any guidance for this problem? Thanks in
advance for your help.
-JoshI was testing on IE8, Windows7 Starter. I don't have IE6 available to test on. Can test on IE7 a bit later on, but I have to fart-arse around with a VM to get it ready, so I'll do that after work.
I tested multiple submits both via clicking between the tabs within one main "request" as well as multiple entire requests (like via refreshing the whole browser window). I had no problems.
I think you're being quite optimistic ot expect AJAX stuff to work reliably on IE6. IE6 crashes. That's what it's most famous for doing. One needs to expect crashes if one pushes it (push it anywhere than out the window, that is). And your client company's IT dept should be lined up against a wall and shot for still running it. That's professionally negligent IMO. But... you probably don't need to be told that.
