Problem using TabBarController and NavigationController in IB

Does anyone know how to add it? Always can't get both of it working! Please Help!

Interface Builder
in AppDelegate:NSObject <UIApplicationDelegate>
I add TabBarController and NavigationController together, is that correct?
IBOutlet UIWindow *window;
IBOutlet UITabBarController *tabBarController;
IBOutlet UINavigationController *navigationController;

It contains transperant tables like BSIS, BSIK etc. For example to take vendor details usr the BSIK.If you use BSEG and BKPF it will take long time search. suppose your concern having lot of data means may be your server will get shutdown. So use only trasnperant tables like BSIS, BSIK etc.

Incorrect. BKPF is a transparent table and not a cluster table and you can use it just like any other transparent table. BSEG is a cluster table but there is no problem selecting from it so long as you use the key of BUKRS, BELNR, GJAHR - unless you are selecting a very large amount of data, but then this can cause problems when selecting from any type of table.
The advantage of using BSEG over the other FI line item tables such as BSIS and BSIK is that it holds all the lines of an FI document while the others will hold only a subset eg BSIK will only hold lines that contain a vendor reference and BSAS holds only cleared GL account lines. Though you can only use it when you have the key. If you need to search on vendor, you can use BSIK as a starting point, but since I usually need to get hold of all the lines on an FI document, I then have to select from BSEG anyway.

Color palette problems using Toolbar and ImageList ActiveX Controls

I'm using Toolbar and ImageList ActiveX controls to implement toolbar functionality in a top-level VI.
I designed the icons used in the toolbar with a 256 color palette. When I initially added the icon images to the ImageList control and ran the VI, the icons were properly displayed in the toolbar, as expected. After saving VI, exiting LabVIEW, and reloading, it appears that a different palette has been applied to the images in the ImageList control. I'm attaching a screenshot of the problem as well.
Has anyone encountered this type of problem before? Any suggestions you provide will be greatly appreciated.

BUG? JDev 10.1.3.1.0 on MacBook Pro - problem using space and delete keys

Is anyone using JDev 10.1.3.1.0 production release on a Macbook Pro? I am experiencing problems using the delete and space keys. The delete key no longer seems to work at all when using any of the key bindings including Default MacOS X. Using the spacebar also seems to have a conflict with the code completion feature. I am finding that the code completion always pops up when the space bar is used and no space is inserted with the editor. The space bar only works when used in conjuction with the shift key. Can anyone verify if they are able to use these keys in JDeveloper 10.1.3.1.0 on a Macbook Pro?
Thanks,
Richard

This was from the dmg file.
I found that in Preferences | Accelerators, Completion Insight lists 'Space' as an accelerator, right after 'CommandAIC'. Removing that fixed the problem, but I still can't fix the Delete issue.
The Delete action is assigned to the 'Delete' key, which is recognizes as the key combination fn-Delete. I tried to assign the Delete Previous Char to just the delete key, but pressing the Delete key while in the New Accelerator field is not recognized - it just pretends as if I had not pressed a key.
I'm looking at the the file:
jdevhome/system/oracle.jdeveloper.10.1.3.39.84/Default_macosx.kdf
trying to find entries for Delete and they are not in there - is there some other place I should be looking?
Thanks,

Problems using Hotmail and Twitter in Firefox

I'm having problems using both Hotmail and Twitter in Firefox (and Google Chrome) but they both seem to work fine in Internet Explorer. I can log-in to both sites but in Hotmail the drop-down menus and links don't work, and in Twitter the stream does not appear at all.
I've tried everything: deleted cache, history, cookies, disabled add-ons etc... I've also tried re-installing both new and older versions of Firefox and I've still had no joy. If anybody has any ideas for a fix I'd really appreciate it. I can't stand using IE but I am forced to at the moment.

My problem with Firefox & yahoo seems similar - so you are not alone.

Problems using MAX and PXI 8186 RT

Hi all !
I'm facing to problems using MAX
1) We have a 1GB switch in order to connect my PXI 8186 RT controller and the host PC, when i use this switch, and i try to access the cards plugged in the PXI card with MAX, MAX crash! When i use a 10/100 Mb switch everything is ok, i can access to the card without any problem ! I know the PXI 8186 controller is only fitted with a 10/100 Mb Ethernet card, but i think that must not be a problem , am i wrong ? Is this problem a known bug ??
2) I want to install all software used by my application on the host computer (in order to be able to reinstall the PXI8186 controller in case of a crash)! To do that i installed MAX 3.1.1, then all drivers NI-DAQmx 7.4, CAN2.2, VISA 3.3, and finally Labview RT 7.1 Embedded on my gost computer! After that i tried to download these software in the controller using MAX! The problem is these software are on the host computer (there are visible in system/ software) , but when i try to install them on the controller, max don't see them ! I tried to uninstall and re-install all software but no changes ... Is there a procedure or an order to install all these software ??? What should i do ???

Hello,
The process to install software on RT controller is :
1/ Install LabVIEW Real-Time 7.1 on your host computer
2/ Install all driveres you need on your RT target
3/ On your host machine, in MAX, go to "remote targets"
4/ Expand "Software"
5/ Clik on "Install" button.
This application note will give you more details about above process.
Our controller is only provided with 10/100 MB network device. You have to check if you can configure your 1GB switch into 10/100 MB.

Problem using JDBC and MS SQL Server

I got a problem trying to acces a database on my SQL Server. I created the table and my connection seems ok, but when i try to get some data from a table, this happens (see below).
java.sql.SQLException: [Microsoft][ODBC SQL Server Driver][SQL Server]Invalid object name 'players'.
at sun.jdbc.odbc.JdbcOdbc.createSQLException(JdbcOdbc.java:6879)

at Simulator.main(Simulator.java:5)
here's the code that i used to access the db with:
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection conn = DriverManager.getConnection
("jdbc:odbc:BRAIN2WINXPPJH","sm","sm");
Statement stm = conn.createStatement();
String query = "Select * from players where teamnr = " + nr +
" order by squadnr";
ResultSet rs = stm.executeQuery(query);
any help is more than welcome
tnx
Jo

If all the tables are in the same database, you can use
Connection.setCatalog("db-name")
to change the current database. But the suggestion to include the database name in the SQL statement is safer, because you do not need to worry about changing the database at the right point.

PROBLEMS USING WEBUTIL_FILE_TRANSFER AND CLIENT_HOST COMMAND TO VIEW BLOB

I am using webutil_file_transfer.DB_To_Client_with_progress to retrieve a blob
from the database (that was saved in a word format) into a .doc file on the
client.
1st problem: The document that is being saved is not readable. It has all
kind of special characters in it.
Then using the client_host command, I open the document into ms word.
2nd problem: The document opens fine (again not readable in garbage
characters) but when I close the document, notepad pops up blank with nothing
in it.
Below is a sample of the code.:
PROCEDURE DOWNLOAD_DB IS
l_success boolean;
username varchar2(30);
document_name varchar2(20);
wordexe varchar2(20);
BEGIN
     username := webutil_clientinfo.get_user_name;
     document_name := 'wo'||:wod.fk_work_order_number||'.doc';
     :locals.file_name := 'Documents and Settings\'||username||'\my documents\'||document_name;
l_success := webutil_file_transfer.DB_To_Client_with_progress
(clientFile => 'C:\'||:locals.file_name
,tableName => 'DEFECTS'
,columnName => 'DESCRIPTION'
,whereClause => 'FK_WORK_ORDER_DATE_ID = '||:DEF.FK_WO_DATE_ID
,progressTitle => 'Defect document being opened'
,progressSubTitle=> 'Please wait'
if l_success
then
CLIENT_HOST('cmd /c start /wait winword.exe C:\'||'"'||:locals.file_name||'"');
else
message('File download from Database failed');
end if;
exception
     when others
     then
     message('File download failed: '||sqlerrm);
END;
Any ideas?

Hello,
I use this kind of code with 9i and 10g and it works fine with word, excel and any of windows files.
I think that, if the file is not correct, the cause may be the first save of the file in the database.
Which instruction did you use to save first the doc in the BLOB column ?

The error message is pretty much telling you the problem:
mappedBy reference an unknown target entity property: domain.Termin.person in domain.Person.termine
This tells you that there's a mappedBy setting on the Person class's termine property annotation, and that the property it's referring to (the person property of the Termin class) doesn't exist.
@ManyToMany(mappedBy="person")
public List<Termin> getTermine() {
   return termine;
}If we have a look at the Termin class, indeed it has the following properties:
id
teilnehmer
titel
eigentuemerAnd no person property. Remember, a property is defined by the existence of a get/set pair for the name. It's unrelated to the types returned by them and the private variables implementing them.
mappedBy has the equivalent effect to the inverse property in a hbm.xml mapping file - it defines which entity's property will cause the foreign key value to be updated (persisting the relationship to the database). From the context of your code, I'm guessing you really want the annotation to read:
@ManyToMany(mappedBy="teilnehmer")

Character encoding problem using XSLT and Tomcat on Linux

Hi,
I have an application running on a Tomcat 4.1.18 application server that applies XSLT transformations to DOM objects using standard calls to javax.xml.transform API. The JDK is J2SE 1.4.1_01.
It is all OK while running on a development enviroment (which is Windows NT 4.0 work station), but when I put it in the production enviroment (which is a red hat linux 8.0), it comes up with some kind of encoding problem: the extended characters (in spanish) are not shown as they should.
The XSL stylesheets are using the ISO-8859-1 encoding, but I have also tried with UTF-8.
These stylesheets are dynamicly generated from a JSP:
// opens a connection to a JSP that generates the XSL
URLConnection urlConn = (new URL( xxxxxx )).openConnection();
Reader readerJsp = new BufferedReader(new InputStreamReader( urlConn.getInputStream() ));
// Gets the object that represents the XSL
Templates translet = tFactory.newTemplates( new StreamSource( readerJsp ));
Transformer transformer = translet.newTransformer();
// applies transformations
// the output is sent to the HttpServletResponse's outputStream object
transformer.transform(myDOMObject, new StreamResult(response.getOutputStream()) );Any help would be appreciated.

Probably you need to set your LANG OS especific environment variable to spanish.
Try adding this line:
export LANG=es_ES
to your tomcat/bin/catalina.sh, and restart tomcat.
It should look like this:
# OS specific support. $var _must_ be set to either true or false.
cygwin=false
case "`uname`" in
CYGWIN*) cygwin=true;;
esac
export LANG=es_ES
# resolve links - $0 may be a softlink
PRG="$0"
.(BTW, keep using ISO-8859-1 encoding for your XSL)

Serious resource utlization problem using SOAP and 8.0.2

Hi,
I'm running into a fairly serious issues whilst trying to download large attachments from a Groupwise 8.0.2 server using SOAP.
Basically, the problem is as follows: at a client site, there's an inbox with an email that has an attached avi file of about 330mb. Our SOAP client tries to retrieve this file in chunks of 1mb in size (if you try to set the size of the chunks any larger, Groupwise will give you a 59922 error, as 1mb is apparently some sort of hard coded limit). So that attachment corresponds to roughly 330 AttachmentRequestMessage's and their responses, each with a 1mb payload.
When we run our client, the cpu utilization of the Groupwise server takes about a dozen seconds to climb to 100%, every single time we try. Since 100% cpu utilization renders all GW clients more or less inoperable (or at least extremely slow) this is a non-starter.
We changed our client to wait 2 secs. in between requesting each chunk of the attachment. This seemed to help initially, but by the time we had transferred 100mb of the file, cpu utilization climbed to 95% and stayed there until the file transfer was completed.
This is a little disconcerting. We're requesting a megabyte of data from an attachment every 2 seconds, and Groupwise seems to have all sorts of problems in trying to service these requests. As you can imagine, client performance isn't that great at 95% server utilization either. I suppose we could increase the pause to something like 5 seconds, but it seems ridiculous that such simple requests are generating this amount of load.
So my question is 2-fold:
1. can I increase the maximum size of an attachment part chunk? 1mb is not very much at all, seeing as our server is on the same gigabit lan segment as the GW server
2. why does cpu utilization shoot up to 95% while servicing what seem to be fairly simple requests, and how do I avoid this by some means other than increasing my pause time?
Thanks in advance,
Maarten
PS I spent some time looking for the 59922 error code in the docs, but turned up nothing

The 59922 error is just a warning.
You should use the HTTP GET construct to get large
attachments. It is orders of magnitude faster than
using getAttachmentRequest.

Problems using JNI and JSP in WebLogic 6.0

Hello everybody. My problem is that I've got a Java class that is called from a JSP. That class connects to a C function and it returns a String. A want this string to be shown by the JSP. The code is:

Is there any place where I have to put the .dll?
Is there any place where I have to put the generated .lib?
Where do I have to put the Texto.h file generated with javah?
Can anybody help me to solve this problem?
Thanks in advance.

Hi, jschell! Maybe you can see my problem if I give you the code. My Java class and the C funtions are:
Java class
package ejemplos.cadena;
public class Texto
private native String getLine(String prompt) throws Exception;
String cadenaFinal = null;
public static void main(String args[])
Texto t = new Texto();
static
System.loadLibrary("LibreriaCadena");
public String realizado(String cadena)
try
cadenaFinal = getLine(cadena);
catch(Exception e)
System.out.println(e.toString());
return cadenaFinal;
C code
#include <stdio.h>
#include <jni.h>
#include "ejemplos_cadena_Texto.h"
JNIEXPORT jstring JNICALL
Java_ejemplos_cadena_Texto_getLine(JNIEnv *env, jobject obj, jstring prompt)
int cero =0;
int division = 10 / cero;
const char str = (env)->GetStringUTFChars(env, prompt, 0);
(*env)->ReleaseStringUTFChars(env, prompt, str);
return (*env)->NewStringUTF(env, str);
I have done something like "int division = 10 / cero;" in order to get an exception in my C code. When I run my Java class I get an error message and the application breaks. I would like to know how to catch the C exception in order to pass it to my Java class that can manage it into the try-catch clause. I have read I have to use something like "FindClass" or "ThrowNew", but my problem is that I have no idea about C programming.
Can you help me?
Thanks for your time.

Problems using BDC and/or HR_INFOTYPE_OPERATION

Hi Gurus.
Our team is developing several inbound HR interfaces but in integrated test in QAS env something really strange is happening during the tests.
We are using BDC data for data input in infotypes 0000 and 0001 through PA30 and for all the other infotypes we use HR_INFOTYPE_OPERATION.
Sometimes data input for 0000 and 0001 works, sometimes no, our table log gives us that the data was processed but when we check on the infotypes there is no data there. The BDC mapping was checked several times and we did some tests in another enviroment, everything is ok, the data is processed but in QAS we are having this problems.
With HR_INFOTYPE_OPERATION, when we run in background mode it give us strange error logs like "a complex application error occurs" but when i did a debug inside of that FM there is nothing missing or nothing wrong.
The enviroment seems to be very instable but basis teams says that there is no log error, but i've never seems errors like these, sometimes works, sometimes no.
The last info that i had is QAS instance that we are using was deleted 3 weeks ago and restored again.
Any suggestions?
Thanks a lot.

Hi,
If your BDC mapping is correct, check the return code after your BDC is excuted with - BDCMSG. Make sure that you give Refresh BDCDATA for every loop.
Having said this, I have also had issues with BDC every there was no error at the end, however the infotype never got updated.
Please double check all the relevant screens. I found that for a particular Inf that I was updating, the subtypes belonged to differnt screens. Can you test with the same data in your Dev or some other box? If that doesnt work, there might be a data issue.
Generally the complex application error occurs when a screen have been modified to prohibit batch processing. It is very difficult to diagnose the error in such cases. Make sure that you are passing all the important data to the FM. You might be able to get more help by searching in this forums as well.

A problem using serialization and/or not overwritten variables

I have a problem while writing objects in ObjectOutputStream :
Here is a simplified version of the program :
class InDData implements serializable
     private Vector shapeVector = new Vector ();
     public InDData (Vector shapeV)
          this.shapeVector = shapeV;
     public int getShapeVectorSize ()
          return (this.shapeVector.size());
class InDShape implements serializable
     private Vector points = new Vector();
// client side
ObjectOutputStream p = new ObjectOutputStream(new BufferedOutputStream (connection.getOutputStream()));
InDData objectData = (InDData) vectorObjectsToBeSentThroughNetwork.remove(0);
System.out.println(objectData.getShapeVectorSize(); //print 1
p.writeObject(objectData);
p.flush();
//server side
ObjectInputStream in = new ObjectInputStream(new BufferedInputStream (connection.getInputStream()));
Object oTemp = in.readObject();
if (oTemp instanceof InDData)
     InDData objectData2 = (InDData) oTemp;
     System.out.println(objectData2.getShapeVectorSize(); //print 2
Some explanations before the main dish :)
I am writing a client that allows you to draw a figure and send it to the network. The drawing is composed of shapes and each shape (class InDShape) is composed of points. For the drawing to be sent to the network, i add the shapeVector (== drawing) to the class named InDData (this class allows me to add some more information about the client and the object sent, not shown here) and then i write the object InDData created in the ObjectOutputStream.
Before writing InDData to the ObjectOutputStream, i test to see if it has a good shapeVector by drawing the shapeVector at the screen. This always shows the same copy as the last drawn panel.
We suppose that the drawing is sent to the network after each drawn shape
(mousePressed -> mousseDragged -> mousseReleased)
(<------------------------------- shape ------------------------------->)
now the problem ;)
When i start drawing, the first shape is sent through the network without any problem.
As soon as i add a second shape to the drawing (shapeVector.size() == 2) things get weird.
The drawing sent to the network is made only of the first shape, nothing more.
     output of program after the 2nd shape was drawn
     client print 1 : size is 2
     server print 2 : size is 1
Alright seems like the shapeVector is truncated...
Now i tried something else to see if the it's only the Vector which is truncated or anything else.
After adding a second shape to the drawing, i delete the first shape of it:
     reprenstation of the shapeVector:
     ([shape1])
     ([shape1][shape2]) // added the 2nd shape
     ([shape2]) // deleted the first shape
     ([shape2][shape3]) // added a third shape. Vector sent to the network via InDData
     output of program with the vector shown above
     client print 1 : size is 2
     server print 2 : size is 1
Additionnaly you might expect me to say that first element of shapeVector inside both class InDData (client and server) are the same, but unfortunately they are not.
The shapeVector received by the server via InDData is the same as when i drew the first shape :((
Here is the problem (!) :(
I think that i have a variable that is not overwritten somewhere but i don't know because:
objectData is overwritten each time a message is sent to the server and has the correct values inside.
objectData2 is overwritten each time a message is received from clients.
Sorry for the huge post, but i believe that explanations are necessary ;)
I am using the 1.4.2 jvm (not tested on others) with Xcode (apple powerbook g4 12").
Thank you all :)

Update :)
In my way of making my program "simple" i forgot an important point in the client side :
// client side
ObjectOutputStream p = new ObjectOutputStream(new BufferedOutputStream (connection.getOutputStream()));
while (connectionNotEnded)
     synchronized (waitingVector)
          try
               waitingVector.wait();     // the only purpose of the Vector is to make the thread wait until it is interrupted to send InDData
          catch (InterruptedException ie)
               System.out.println("Thread interrupted");
     InDData objectData = (InDData) vectorObjectsToBeSentThroughNetwork.remove(0);
     System.out.println(objectData.getShapeVectorSize(); //print 1
     p.writeObject(objectData);
     p.flush();
I need it to explain the solution of my problem.
when I am creating a client, a thread is created with the above code. It creates the ObjectOutputStream and then wait patiently until said to proceed (Thread.interrupted()).
I do not close the ObjectOutputStream during the program running time.
So whenever I am writing an object to the stream, the stream "sees" if the object was created before. I suppose that the ObjectOutputStream has a kind of memory for past written objects.
So when i send the first InDData, the ObjectOutputStream's memory is "empty", thus the correct sending (and serialization) of InDData.
But whenever I try to write another object of the same type InDData containing approximately the same data (shapeVector), the ObjectOutputStream calls its "memory" and tries to find it in the past written objects. And finds it in my case ! That's why whatever i put in the shapeVector, it ends by being the first shapeVector sent through the network. (I assume that the recall memory process lacks of "precision" in identifying the memory's object or that the process to give a unique serial to the written object in the ObjectOutputStream "memory" is limited).
I tried the different ObjectOutputStream writing methods :
instead of p.writeObject(objectData) i put p.writeUnshared(objectData).
But as it is said in the docs : " While writing an object via writeUnshared does not in itself guarantee a unique reference to the object when it is deserialized, it allows a single object to be defined multiple times in a stream, so that multiple calls to readUnshared by the receiver will not conflict. Note that the rules described above only apply to the base-level object written with writeUnshared, and not to any transitively referenced sub-objects in the object graph to be serialized."
And that is exactly my case !
So i had to take it to the next level :)
instead of trying to make each written object unique, i simply reset the stream each time it is flushed. That allows me to keep the stream opened and as fresh as new ;) I think the cost of resetting the stream is higher than writeUnshared but lower than closing and creating a new stream each time otherwise it would not have been implemented ;)
Here is the final code for the client side, the server side remains unchanged :
// client side
ObjectOutputStream p = new ObjectOutputStream(new BufferedOutputStream (connection.getOutputStream()));
while (connectionNotEnded)
     synchronized (waitingVector)
          try
               waitingVector.wait();     // the only purpose of the Vector is to make the thread wait until it is interrupted to send InDData
          catch (InterruptedException ie)
               System.out.println("Thread interrupted");
     InDData objectData = (InDData) vectorObjectsToBeSentThroughNetwork.remove(0);
     System.out.println(objectData.getShapeVectorSize(); //print 1
     p.writeObject(objectData);
     p.flush();
     p.reset();
And that solves my problem :)

Forcing Landscape orientation for TabBarController and NavigationController

Hello,
I'm writing an application that need to force LandscapeRight with a UITabBarController that contains a UINavigationController that contains UIViewController.
I can force UIViewController to landscape, but when I add the UINavigationController, the emulator starts as Landscape, but returns to Portrait when I call [window addSubView:], and the viewOrientation field from window switch from 0 to Portrait.
Is there anybody has worked with landscape orientation ? (it's really hard to make a landscape app, indeed).
David

The code below almost works. It does force landscape orientation. The problem I am having is that the navigation items in the navigation bar are not centering themselves until the device is physically rotated. Hope it helps.
Ed
[window addSubview:[navigationController view]];
[window makeKeyAndVisible];
// get height of status bar before setting the status bar to landscape orientation
CGRect statusBarFrame = [[UIApplication sharedApplication] statusBarFrame];
// set the status bar to landscape orientation
[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeRight animated:NO];
// rotate
UIScreen *screen = [UIScreen mainScreen];
CGRect newBounds = CGRectMake(0, 0, screen.bounds.size.height, screen.bounds.size.width - statusBarFrame.size.height);
self.navigationController.view.bounds = newBounds;
self.navigationController.view.center = CGPointMake(newBounds.size.height / 2.0, newBounds.size.width / 2.0);
self.navigationController.view.transform = CGAffineTransformConcat(self.navigationController.view.transform, CGAffineTransformMakeRotation(degreesToRadian(90)));
self.navigationController.view.center = window.center;
here is the function definition
#define degreesToRadian(x) (M_PI * x / 180.0)
