At the moment there's no tools.jar in SableVM.  This should be fixed by
the end of April.  Usually the only reason an app needs tools.jar is
to call the Sun's compiler.  This is also why you're getting the above
exception.

In such case you always have to tell such a program not to use the Sun's
compiler interface in tools.jar, but to use an external compiler (jikes)
instead.

You said you modified the web.xml but apparently jasper still looks for
Sun's compiler, instead of using jikes.  Maybe you could try out the
second instruction:

by adding "-Dbuild.compiler.emacs=true -DjavaEncoding=ISO-8859-1" to
your CATALINA_OPTS as well?

especially that there's plenty of people who will run into identical
problems.

Actually, when you're done, would you be able to go to

	http://sablevm.org/wiki/Tomcat

and write something in a shape of a step-by-step instruction about
how to get Tomcat working with SableVM?  Later you could also point
debian-alpha guys to that (I'll be uploading a new SableVM debs shortly,
so that it wasn't necessary to recompile with 'direct' on alpha).
