Cherif,

	Yes, that is my understanding, too.

	Yes, I agree.

	Again, I agree. It is interesting that Ethan eventually solved his
problem by stopping his use of GCJ.

	With all due respect to Ethan, I sense that the root of the problem was
that he did not understand J2EE web administration. In particular, Ethan
did not seem to understand how Tomcat works or how properly to configure
its Java environment.

Sincerely,
