There are a couple things to be aware of here. There are some issues with having a WebApp project depend on a Java project. The crux of the problem is that the artifacts from the Java project are not automatically copied over to the WebApp's war directory. See the following thread for more information:
http://groups.google.com/group/Google-Web-Toolkit/browse_thread/thread/951499c5773693c9 Another problem may be that you're explicitly including Xerces as part of your WebApp project libraries (or maybe one of the libraries that you're using bundles Xerces). There is no need to deploy your own Xerces library; one is already available to the platform, and adding your own can cause ClassLoading issues.
