Re: Debugging Java Program?

Scott:

When you're trying to debug Java on the iSeries server, make sure that you 
created the Java program (CRTJVAPGM) with 
a low optimization level (10).  If you set the optimization level too high 
you can no longer debug it. 

I've tried adding the debug option when compiling the java program but 
found that it didn't make a difference, since I was still able to debug 
it.

I'm not sure if you've been able to bring up your java code and set a 
breakpoint, but check my posting of July 4th to get the info.

I've had a lot of sucess debugging once the Java Virtual Machine (JVM) has 
been started up by the RPG code. 
I set a break code in my RPG pgm just after I called my constructer in the 
Java code. 
Then I've gone into the Interactive Debugger and added my Java class to 
the module list.
After adding it to the module list, I can select my Java code, and set a 
break point in it. 
I continue to run my code and it stops in my Java program.

NB:  You will not be able to add the Java to the module list, until your 
costructor gets run because, that is what starts up the JVM.Machine.  Also 
make sure you have your environment variable CLASSPATH setup properly.
