How to capture Java Exceptions in batch file

I have a batch file that calls java class. When the java class throws exception, how do I capture the exception as an error message in batch file.

This is the java program

import java.io.*;

publicclass Test{

publicstaticvoid main(String []args){

String wantThisToFail=null;

try{

if (wantThisToFail.equals("SomeString") ){

System.out.println("Testing");

}

}catch (Exception e){

System.out.println("Exception " + e);

}

}

}

This is the batch file

@echo off

echo Testing

REM execute the javaclass

java Test

set deployError=%ERRORLEVEL%

echo %deployError%

IF NOT %deployError% == 0 (

echo failed

)else (

echo succeeded

)

Since the java class throws NullPointerException, i want the batch file to show "Failed" Message.

Please Help!!

Try capturing the return value of the command "java Test". If it succeeds, you should get a '0', otherwise you'll get something else. I admit it's been years since I had to do that, but it rings a bell. If it works, and you're on Java 5 or later, you can use the method Thread.setDefaultUncaughtExeptionHandler ( look at the docs ) and from there use System.exit(<your integer value return code here>) for more control over the return value

Thank you george for the suggestions. But my hands are tide here and i cannot make any change to the java program, the only change i could do is at the batch file level.ERROLEVEL is always displaying "0" here.

If you can't change the java code, how can we help you? This doesn't seem to be a java question. Perhaps you can find a batch forum somewhere?

System.exit() worked here. Thanks george!
