    JAXB object serialization failure under weblogic

    931605
      This is the simplified scenario:

      Using JAXB code the first line below will fail on some of the objects I'm using:

      context = JAXBContext.newInstance( MyClass.class );
      Unmarshaller unmarshaller = context.createUnmarshaller();
      StringReader rdr = new StringReader( input );
      Object obj = unmarshaller.unmarshal( rdr );

      When I run the code using a simple command line java program using 1.6 java w/ no special classpath the code works but when I copy
      the code into a weblogic ear project, the same exact code fails. Well, it fails under windows but seems to run ok under the linux cluster.
      The exception I get is:

      <exception code="UNKNOWN">com.sun.xml.bind.v2.runtime.IllegalAnnotationsException: 1 counts of IllegalAnnotationExceptions
      If a class has @XmlElement property, it cannot have @XmlValue property.

      So, I'm guessing jrocket JAXB is running things a little more strict than plain old java under windows? Is there anyway to
      get weblogic to use the plain java JAXB path through the code? Maybe a classpath setting will fix this?

      Also, I'm still pretty new to weblogic and I was tying to repro the scenario outside of weblogic but haven't been successful. Is it
      possible to run a simple java program (.class files only) under the weblogic VM/class loaders w/out starting up the server?

      thanks,
      Paul.
