I think you mean how do you optimize your .WAR file, right ?

That is currently a TODO https://jira.jboss.org/jira/browse/TTALE-12, but you can extract it and run Tattletale on that directory.

Of course it depend on if you have a lot of import's in your pages - a solution would be to bundle up all generated .class files and add them to the extracted directory.

But describe your use-case in more detail.
