Java InvocationTargetException - how to debug ?

Hi from Brazil,

I am developing an Firefox Extension with Javascript and Java. I´m using JSS
library (jss341.jar) and JavaConnect is being included too (moztools.jar).
I´m having an exception thrown when trying to register the "Mozilla-JSS"
service provider. I tried to debug by building the .class files with
breakpoints into mozilla components dir (and loading them from javascript),
but the brakpoint won´t work. Is there any way to trace messages ?

The alert displays:

JavaScript Application
Error: java.security.PriviledActionEvent: java.security.PriviledActionEvent:
java.lang.reflect.InvocationTargetException

And here is the code.

		try
		{
	        String dbdir = getMozillaDir(); // there is an breakpoint here but
it won´t "break" here

	        System.load( "jss3.dll" );

	        CryptoManager.initialize( dbdir );

	        Debug.setLevel(Debug.OBNOXIOUS);

		} catch (GeneralSecurityException e) {
			throw new XPCOMException("GeneralSecurityException");
		} catch (AlreadyInitializedException e) {
			throw new XPCOMException("AlreadyInitializedException");
		} catch (KeyDatabaseException e) {
			throw new XPCOMException("KeyDatabaseException");
		} catch (CertDatabaseException e) {
			throw new XPCOMException("CertDatabaseException");
		}

Any help ?

Thanks,
Murilo
