This is the right place.

I would have thought this was a simply "javac" compiler mismatch, but
that doesn't appear to be the case given the other posts in this thread.

Interesting that the JSP compiler uses the Eclipse compiler, here. :)

It's possible that the internal compiler requires a certain level of
class file. Were there any /other/ messages in your log files and/or
error report?

Has Eclipse (outside of Tomcat) been configured to emit .class files in
a certain format? I'm guessing this hasn't been done for 'ant', so maybe
they need to match each other.

Really? Hmm. Could you double-check that and post what you get?

It's possible that there's a bug in the compiler that can't read some
particular thing in the class file.
