Ok, back up and start over. First, extract the classes
from the jar file into an empty directory. Then, add that
directory to your env(TCL_CLASSPATH). Make sure the
.jar file is not sitting in the directory you just created.
Then call your java main method like so.
java::call mypkg.myclass main
If that works, jar up your files, remove the dir you just created
and try it again.

Try running "javap -verify class" just to make sure the
file is not hosed in some strange way.

Humm, I am not sure what that means. If your class
depends on another class that can not be found that
might be part of the problem. The TclClassLoader
should give you an error message in this case.
Oh right, the improved TclClassLoader error
message stuff has not been released yet. You could
try grabbing the 1.2 branch from the CVS like so.
The 1.2 branch includes only bug fixes for 1.2.5
that have yet to be released.
setenv CVSROOT :pserver:[EMAIL PROTECTED]:/cvsroot
cvs login (password is cvs)
cvs checkout -r branch-1_2 tcljava
cd tcljava/unix
autoconf
mkdir Build_Jacl
cd Build_Jacl
../configure --with-build=jacl --prefix=$your_prefix
make
make install

You are not still calling java::new like this, right?
java::new x.y.z.class
It needs to be like this:
java::new x.y.z

I hope that helps
