Catching exceptions in JPL

Does anyone know of a way to catch a Java exception from JPL?  For example,
I have a login method in Java that throws an exception if the login fails
for any number of reasons.  I have JPL code that calls the login method
from Perl but since the method is a void method, I get no return value to
evaluate for success or failure.  The login code is not mine or I would
change it to return a boolean just for this reason.

So, how can I access the exception stack to check for a failure?

Here is some pseudocode of what I am talking about.

Java method
===========

public static void login (String[] args)
{
     try
     {
          // login
     }
     catch (Exception e)
     {
          // display reason for failed login
          // exit code
     }
}


JPL Perl sub
===========

     $username = "me\\you\@thisplace.com";
     $login = JPL::AutoLoader::getmeth('login',['java.lang.String'],[]);
     &$login($username);

     # if (exception) {
          # error message
          # exit program
     #}

Any ideas would be appreciated.  Thanks!

Cheers,
Scott.
