What? The JAR utility does not support symlinks, so your JAR tool is
likely putting the whole file into the WAR archive.
Now, ZIP files *do* support symlinks, but I'll bet that Java will
fall-over if you try to open a ZIP file and it encounters a symlink in
there.

Tomcat doesn't expand anything. If you have a WAR file with an "alias"
configured in it, it will just access the aliased directory directly.

Can you explain this in a little more detail? Remember that nobody
here has any idea what your application does, or what you expect to
happen.

The aliases setting is completely independent from any symlink
business you've got going on.

I would just use the aliases setting and remove the symlink entirely.
The entire purpose of "aliases" is to allow you to have the effect of
symlinks, but do it in a safe way (that doesn't delete all your
symlinked files when you undeploy the web application, for instance).
