I think this issue has more to do with solving the issues with java builds
based in ant or maven than finding bundled jars... currently almost every
Java package out there is built using either ant or maven (please, some Java
Gentoo developer correct me if I'm wrong). In the case of maven, jar
dependencies are not bundled with source files, they are specified as
dependencies in the project descriptors. In the case of web applications,
those dependencies are downloaded from binary repositories, and bundled in
the WEB-INF/lib directory of the war file at build time. The obvious
solution (don't know if easy to implement, I remember some discussion here
regarding this) is to intercept in some way the maven dependency resolution
mechanism and instead of downloading binary jars, take jars from the java
packages already installed by Gentoo.

In case you still want to go the explode/replace way, as Andrew tells, you
won't be able to use symlinks, as some app-servers can't deal with exploded
archives. You should replace those jars with jars present on the system, and
then repackage and deploy the archive. I see this more unnatural than the
previous solution, although maybe easier to do.

Best regads
