Hi, my problem is how to
change a java code on wcl.
I want to replace
EventHandlerHomeImpl2.java
with

Changing java code using Java program

hi All,
I have some java classes, which i need to modify. The changes are mechanical, like putting finally block for the methods where there is a try block.
Please suggest on how to write a small java program that will accomplish the task. Some code snippets may be helpful.
Thanks,
Raj.

no, you got me wrong. After i add the finally blocks,
i will perform the clean up tasks there. The first
part of adding the finally blocks,i want to perform
using a program.No you really don't want to do this.
a) This will not be easy and in fact will be quite messy.
b) It doesn't gain you anything anyway. As you yourself just noted you will have to put appropriate code in all those blocks anyway.
So give this up and do it manually and for next time you will have learned that you should follow the standards from your project from the start.

How to get No. of rows affected by Update or Delete in Oracle in Java Code?

All,
I know that sql%rowcount can give me the rows affected. But I want to get this number directly after OracleCallableStatement.ExecuteUpdate?
Thank you.

kellerer,
I appologize for what I said.
I gave a not clear question. And some rude words.
One my colleague wrote below code in order to get the affected rows after update data in Stored Procedure in Oracle. But it didn't work, so another colleague had to change the code. I think the best way is not to change Java code but change code in Stored Procedure. You know it was Friday, we all supposed to fix that change this week, I got the link you gave and tried to fix that using return in Stored Procedure. But still couldn't work after tried many times. Because I told my colleague how to change code, I had to take the responsibility, I was too impatient to write those rude words. Sorry.
int success = cs.executeUpdate();

How to change InputField background color using Java Code

Hi,
In my application use will enter some set of Cost Centers in a table and submits request.
In return i will get a list of invalid cost centers which i need to display in a table with input field
In that table all cost centers will displayed, but invalid cost centers should be highlighted or background color should some other color. like red or yellow.
Is it possible using java code to change a input field color.
Please help me.
Thanks

Hi,
    declare a error message in message pool and declare a method say "checkCostCenters " and in this method, u can check whether it is a valid cost center .. if it is invalid cost center , then throw the erro message using the below code :
wdComponentAPI.getMessageManager().reportContextAttributeMessage(
                    inputfieldattibutePointer, IMessageProgramPlanComp.ur error message,
                    new Object[] );
for getting pointer and label use the below code:
IWDAttributePointer inputfieldPointer = URNODEELEMENTElement
                    .getAttributePointer(URNODEELEMENT.ATTRIBUTENAME);
          String inputfieldLabel = wdContext.nodeURVALUENODE.getNodeInfo()
                    .getAttribute(URNODELEMENT.ATTRIBUTE).getSimpleType()
                    .getFieldLabel();
hope it helps..

IS IT POSSIBLE to change SCREEN's RESOLUTION thru JAVA code?

Can I change the screen resolution of the PC (through my Java code) where my application will run? is there any possible way to do this?

Hi.
Sure it's possible if you use JDK 1.4, you can switch to fullscreen mode and change the displayModes throug methods like :
java.awt.GraphicsDevice :
public void setDisplayMode(DisplayMode dm)
public DisplayMode getDisplayMode()
public DisplayMode[] getDisplayModes()
You can browse to for more information

Web Dynpro Java code changes

Hi,
I need to put some validations in web dynpro java page which is "employee address page". I checked the BADI's but no badi exists which serve my purpsoe.
Now I want to make the code change in web dynpro java. Pls answer the followng questions.
1- I have installed NWDS on my local machine. Do i need to install NWDI also?
2- How to import and export the required page and from where?
3- How to modify the standard code, I mean in ECC we have enhancement and modification concept.
Thanks,

NWDI is a part of NWDS, So you would need both as mentioend
NWDI - Netweaver Development Infrastructure is an SAP sytem for java development & change management. It's a repository for java code and change management system.
NWDS is a developer tool to build applications similar to Eclipse. NWDS uses NWDI to check-in & check-out java code and move java changes to SAP runtime systems (like portal etc).
Read the basics of NWDI and its utility in the below help document

Can I change the Jar contents trough Java code ?

It may seems a little bit wierd, but it could solve a lot of acessibility problms....
Can I change/set the jar contents using java code ?
My real problem: I'm creating a EDI Client and using a XML file as configuration file. It's running well but this XML is much exposed to unauthorized users....
Can I set a value in this XML file if it is inside a jar file ??

you can look at class JarOutputStream . You could also use class RunTime to just create a new jar with the proper files via the normal jar command.

Change the Summary Attribute Value through Java code

Hi ,
I am working on a requirement where I need to set the Attribute value on the final Summary Screen through Java Code.
Code :
        InterviewUserData data = new InterviewUserData();
        InterviewEntityInstance globalInstance = data.getGlobalInstance();
        globalInstance.setValue("Name", value_to_set);
On completion of the interview session Name is displaying as NULL.
I need to set NAME = value_to_set and display it on the final summary screen.
Any help on this will be appreciated.
Regards

The InterviewUserData object is effectively a change set, to apply this to a session you use the InterviewSession.submit(InterviewUserData) method. You don't say how you are invoking this code but if it's inside an event Interview Engine handler the InterviewSession object should be accessible.

Java code changes deletes when saving webdynpro project

hi guys,
is it always necessary to create methods from wizards in the webdynpro view controller??? other wise if I am already in the code and create some new method which is not created by wizard, it is removed once I am going to save the changes in the java code.
Can any one tell me what should I do??

[UCCx] Change volume of an audio file (java code)

Hello guys,
Thanks to the many examples I compiled on the subject, I was able to create a script that mixes 2 audio wav files into a 3rd one. Basically the goal is to mix a first audio file containing some speech with a second one containing some music, these files being encoded identically (8 bits, 8KHz, mono wav files). The resulting file must be encoded in the same format than the initial ones.
The mixing operation is performed thanks to the MixingAudioInputStream library found online (it can be found here).
It is not the most beautiful Java code (I am no developer), but it works:
Document doc1 = (Document) promptFlux1;
Document doc2 = (Document) promptFlux2;
Document docFinal = (Document) promptFinal;
javax.sound.sampled.AudioFormat formatAudio = null;
java.util.List audioInputStreamList = new java.util.ArrayList();
javax.sound.sampled.AudioInputStream ais1 = null;
javax.sound.sampled.AudioInputStream ais2 = null;
javax.sound.sampled.AudioInputStream aisTemp = null;
javax.sound.sampled.AudioFileFormat formatFichierAudio = javax.sound.sampled.AudioSystem.getAudioFileFormat(new java.io.BufferedInputStream(doc1.getInputStream()));
java.io.File fichierTemp = java.io.File.createTempFile("wav", "tmp");
ais1 = javax.sound.sampled.AudioSystem.getAudioInputStream(doc1.getInputStream());
formatAudio = ais1.getFormat();
aisTemp = javax.sound.sampled.AudioSystem.getAudioInputStream(doc2.getInputStream());
byte[] bufferTemp = new byte[(int)ais1.getFrameLength()];
int nbOctetsLus = aisTemp.read(bufferTemp, 0, bufferTemp.length);
java.io.ByteArrayInputStream baisTemp = new java.io.ByteArrayInputStream(bufferTemp);
ais2 = new javax.sound.sampled.AudioInputStream(baisTemp, formatAudio, bufferTemp.length/formatAudio.getFrameSize());
audioInputStreamList.add(ais1);
audioInputStreamList.add(ais2);
MixingAudioInputStream mixer = new MixingAudioInputStream(formatAudio, audioInputStreamList);
javax.sound.sampled.AudioSystem.write(mixer, formatFichierAudio.getType(), fichierTemp);
return fichierTemp;
The only downside to this is that the music can be a little loud comparing to the speech. So I am now trying to use the AmplitudeAudioInputStream library to adjust the volume of the second file (it can be found here).
Here are the additional lines I wrote to do this:
ais2 = new javax.sound.sampled.AudioInputStream(baisTemp, formatAudio, bufferTemp.length/formatAudio.getFrameSize());
org.tritonus.dsp.ais.AmplitudeAudioInputStream amplifiedAudioInputStream = new org.tritonus.dsp.ais.AmplitudeAudioInputStream(ais2, formatAudio);
amplifiedAudioInputStream.setAmplitudeLinear(0.2F);
audioInputStreamList.add(ais1);
audioInputStreamList.add(amplifiedAudioInputStream);
MixingAudioInputStream mixer = new MixingAudioInputStream(formatAudio, audioInputStreamList);
javax.sound.sampled.AudioSystem.write(mixer, formatFichierAudio.getType(), fichierTemp);
return fichierTemp;
The problem is I always get the following exception when executing the code:
could not write audio file: file type not supported: WAVE; nested exception is: java.lang.IllegalArgumentException: could not write audio file: file type not supported: WAVE (line 30, col:2)
The error is on the last line (the write method), but after many hours of tests and research I cannot understand why this is not working... so I have added some "debugging" information to the code:
System.out.println("file1 audio file format: " + formatFichierAudio.toString());
System.out.println("file1 file format: " + ais1.getFormat().toString());
System.out.println("file2 file format: " + ais2.getFormat().toString());
System.out.println("AIS with modified volume file format: " + amplifiedAudioInputStream.getFormat().toString());
System.out.println("Mixed AIS (final) file format: " + mixer.getFormat().toString());
AudioFileFormat.Type[] typesDeFichiers = AudioSystem.getAudioFileTypes(mixer);
for (int i = 0; i < typesDeFichiers.length ; i++) {
System.out.println("Mixed AIS (final) #" + i + " supported file format: " + typesDeFichiers[i].toString());
System.out.println("Is WAVE format supported by Mixed AIS (final): " + AudioSystem.isFileTypeSupported(AudioFileFormat.Type.WAVE, mixer));
System.out.println("Destination file format: " + (AudioSystem.getAudioFileFormat((java.io.File)f)).toString());
AudioInputStream aisFinal = AudioSystem.getAudioInputStream(f);
System.out.println("Is WAVE format supported by destination file: " + AudioSystem.isFileTypeSupported(AudioFileFormat.Type.WAVE, aisFinal));
try {
// Ecriture du flux résultant dans un fichier
javax.sound.sampled.AudioSystem.write(mixer, formatFichierAudio.getType(), fichierTemp);
return fichierTemp;
catch (Exception e) {
System.err.println("Caught Exception: " + e.getMessage());
Which gives the following result during execution:
file1 audio file format: WAVE (.wav) file, byte length: 146964, data format: ULAW 8000.0 Hz, 8 bit, mono, 1 bytes/frame, , frame length: 146906
file1 file format: ULAW 8000.0 Hz, 8 bit, mono, 1 bytes/frame,
file2 file format: ULAW 8000.0 Hz, 8 bit, mono, 1 bytes/frame,
AIS with modified volume file format: ULAW 8000.0 Hz, 8 bit, mono, 1 bytes/frame,
Mixed AIS (final) file format: ULAW 8000.0 Hz, 8 bit, mono, 1 bytes/frame,
Mixed AIS (final) #1 supported file format: WAVE
Mixed AIS (final) #2 supported file format: AU
Mixed AIS (final) #3 supported file format: AIFF
Is WAVE format supported by Mixed AIS (final): true
Destination file format: WAVE (.wav) file, byte length: 146952, data format: ULAW 8000.0 Hz, 8 bit, mono, 1 bytes/frame, , frame length: 146906
Is WAVE format supported by destination file: true
So everything tends to show that the format should be supported and the mixed AIS should be written to the file... but I still get the error.
I am really confused here, if someone could help it would be great.
Thanks in advance!
PS: I have attached print screens of the actual script, without the "volume adjustment" code.

Hi,
well I started writing a similar solution but it did not work either so I just put it on hold.
I also tried to get hold of the streaming "device" abstraction of UCCX to adjust the volume while "playing" but that was a dead end, too, unfortunately.
Sorry about my previous comment on your StackOverflow post, that time I thought it was kind of out of context but I believe you only wanted to ask about this issue on all available forums.

Some java code returns a null resultset from 10.2.0.1 DB, but works w/ 9.2

I am a Java noob guys, but we have java code the calls an Oracle Function. This code is unchanged from what successfully runs against an Oracle 9.2 database returning, in this case, one row from the database. A ref cursor is used. When the same Java code calls the same ref cursor function from a 10.2.0.1 database, a null resultset occurs. The function correctly returns a single row when executed by the same database user via sql-plus. So it must be a java thing. Does the jdbc driver need to be upgraded to correctly run against a 10.2 database? And is this null resultset type of anomaly a potential result of having a wrong version of ojdbc14.jar? Nothing else has changed except pointing the code to the same package and tables in a 10.2 database.
Thanks in advance for your comments.
Phil McDermott

I realize now that this is the wrong forum to post in, but I was linked here from a google search on the issue.
I downloaded the 10.2.0.1 ojdbc14.jar from oracle, but the problem persists.
yeesh! now what?

Java Code to Convert GIF to BMP

Hi,
Could anyone please tell me the Java Code to convert the GIF image to BMP image.
Thanks,
Rathish

Here is a sample code for reading an Excel file. It uses JExcel API:
package com.quicklyjava;
import jxl.*;
import jxl.read.biff.BiffException;
import java.io.File;
import java.io.IOException;
public class JavaExcelRead {
* @param args
public static void main(String[] args) {
try {
//Create a workbook object from the file at specified location.
//Change the path of the file as per the location on your computer.
Workbook wrk1 = Workbook.getWorkbook(new File("C:/test.xls"));
//Obtain the reference to the first sheet in the workbook
Sheet sheet1 = wrk1.getSheet(0);
//Obtain reference to the Cell using getCell(int col, int row) method of sheet
Cell colArow1 = sheet1.getCell(0, 0);
Cell colBrow1 = sheet1.getCell(1, 0);
Cell colArow2 = sheet1.getCell(0, 1);
//Read the contents of the Cell using getContents() method, which will return
//it as a String
String str_colArow1 = colArow1.getContents();
String str_colBrow1 = colBrow1.getContents();
String str_colArow2 = colArow2.getContents();
//Display the cell contents
System.out.println("Contents of cell Col A Row 1: \""+str_colArow1 + "\"");
System.out.println("Contents of cell Col B Row 1: \""+str_colBrow1 + "\"");
System.out.println("Contents of cell Col A Row 2: \""+str_colArow2 + "\"");
} catch (BiffException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
You can further process this to convert the data extracted into XML. Hope this helps!
