Need help for traping imported java bean exception

Question

hi everyone
i have imported a java bean into my forms 9i using java importer utility which tries to rename a file on a give path(bean works fine when executed through sql client).
i have problem when called from when button pressed trigger, it throws me an ("FRM-40735 and ORA-105101 NON ORACLE EXCEPTION") error.
i have imported java.lang.exception class and constructed an exception handler to trap java exception in the trigger
as
EXCEPTION
     WHEN ORA_JAVA.JAVA_ERROR then
          message('Unable to call out to Java, ' ||ORA_JAVA.LAST_ERROR);
          --check for ORA-105101
     WHEN ORA_JAVA.EXCEPTION_THROWN THEN
          ex:= ORA_JAVA.LAST_EXCEPTION;
          message('Java Exception --: '||BIException.toString(ex));
          ORA_JAVA.CLEAR_EXCEPTION;
     WHEN OTHERS THEN
          message('error :'||SQLERRM);
when i imported java.lang.exception i did not find any wrapper pl/sql function or procedure declared to read or get the error messages except for the functions named "new" ,my exception handler failed.
so i tried with BIException which also fails to trap the error i have no idea about BIException and its usage with in forms ,Please do help me out with this issue ASAP.
thanks in advance

Hi,
don't understand what the BIException is supposed to do in your code, can you try
     WHEN ORA_JAVA.EXCEPTION_THROWN then
     ex := ORA_JAVA.LAST_EXCEPTION;
     message('Exception: '||Exception_.toString(ex));
where Exception_ is the imported java.lang.Exception package.
