ant does not allow using <copy> in <war> block, you may use
<fileset dir="any-dir" />
in your ant file. and then just create a "WEB-INF" directory in "any-dir" directory, and put xml files there.
the directory structure would be like this:
+any-dir
     +WEB-INF
        <xml-files-are-here>

that's how i did it.
