Problem with Kaffe

[Angel Cabello <ac...@masterd.es>]

My developer machine is a RedHat 6.0, I can use Tomcat without problems,
but my production envirotment is RedHat 5.2, I have a lot of thigs in
that machine and I want to avoid upgrating this machine. I can't install
any JVM but Kaffe 1.0.5 in that machine, is a hell machine.

It seems to works right, but when I try to run a jsp, I get that message

[root@intranet bin]# Unhandled error! You might want to consider having
an error page to report such errors more gracefully

JSP pages are translated into Java servlets, which must then be compiled (by a Java compiler) before they
can be used.

By default, JSP page compilation in Tomcat tries to use the compiler from the JDK -- which is apparently
not present in the Kaffe virtual machine.  There are comments in the configuration files about how to use
Jikes as the JSP page compiler instead, if that is possible in your environment.
