It seems that the classes of the JSTL are loaded by a different classloader than the webapp classloader. Because this class loader does not have xalan in place, it fails.
Could you please add xalan to the classpath of this classloder? (If i do this in the eclipse plugin, it works, but only in the local dev environment of course). I added this as a comment on issue 2180.
