Java importer: exception reporting

Question

I am using the Java Importer facility in Forms 6i to call to Java class methods from my form. I'm still at the development stage so my Java class methods raise (unexpected and expected) exceptions periodically. But Forms always reports this as an ORA-105100 error which makes it very difficult to debug.
How can I pass the Java exception back to Forms and have it report the entire stack trace? What about run-time exceptions (e.g. Class not found, Class Cast exception, etc.)?
Thanks,

Hi there
I had the same problem and the documentation wasn't very good.
Try importing 'throwable' (type in something like 'java.lang.throwable' on the input line) and then use the following code.
It doesn't always return very meaningful messages but I geuss needs some refinement.
EXCEPTION
WHEN ORA_JAVA.EXCEPTION_THROWN
THEN
exc := ORA_JAVA.LAST_EXCEPTION;
MESSAGE(throwable.getmessage(exc));
ORA_JAVA.CLEAR_EXCEPTION;
null
