That stack trace is related to the app engine sdk, are you sure you want to use it ?
To further explain the problem: I've seen the same exception in a post a couple of days ago here, the poster eventually found out that he needed a xerces jar in his classpath and that solved the issue (look at the cause of the exception at the bottom of the snippet below) Hope it helps, Salvador > java.lang.RuntimeException: Unexpected exception > at com.google.appengine.tools.enhancer.Enhancer.execute > (Enhancer.java:59) > at com.google.appengine.tools.enhancer.Enhance.<init> > (Enhance.java:60) > at com.google.appengine.tools.enhancer.Enhance.main > (Enhance.java:41) > Caused by: java.lang.reflect.InvocationTargetException > at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) > at sun.reflect.NativeMethodAccessorImpl.invoke > (NativeMethodAccessorImpl.java:39) > at sun.reflect.DelegatingMethodAccessorImpl.invoke > (DelegatingMethodAccessorImpl.java:25) > at java.lang.reflect.Method.invoke(Method.java:585) > at com.google.appengine.tools.enhancer.Enhancer.execute > (Enhancer.java:57) > ... 2 more > Caused by: javax.xml.parsers.FactoryConfigurationError: Provider > org.apache.xerces.jaxp.DocumentBuilderFactoryImpl not found > at javax.xml.parsers.DocumentBuilderFactory.newInstance > (DocumentBuilderFactory.java:104) --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
