    ClassCastException - jaxws webservice in jboss1.2.0

    santhoshitha gokul Newbie

      Hi there!
      I have posted over a dozen questions in this forum but haven't gotten a reply to even one. I hope atleast this one qualifies for a reply.
      I am using jbossws 1.2.0 installed in jboss server 4.0.5. i try to deploy a jaxws webservice that consists of methods accepting an array of custom classes as a parameter and returning an array of strings. i get an exception on deployment which is quite tough to debug. any help/insight into this would be a big help. i am in a fix, and need a solution quickly.
      the exception i get is :


      [ServiceEndpointDeployer] Cannot create service endpoint
      java.lang.ClassCastException: com.sun.xml.bind.v2.model.impl.RuntimeBuiltinLeafInfoImpl$5

      The complete stack trace is below:

      Kindly guide me in this regard.
      Any help is really appreciated, and would help me a lot in proceeding with my work.

          santhoshitha gokul Newbie

          I know that this is something that's got to do with JAXB. how do i get over it? what is it exactly?

          below is my source code :

          @WebService(
          name = "UpdateService",
          targetNamespace = "http://deshaw.com",
          serviceName = "NmUpdateService")
          @SOAPBinding(style = SOAPBinding.Style.DOCUMENT, use=SOAPBinding.Use.LITERAL)
          public class NmUpdateService extends HttpServlet
          {

          /*some declarations and code go in here */

          @WebMethod
          @WebResult(name="returnValues")
          public String[] updateAttributes(@WebParam(name="spn")Integer spn,
          @WebParam(name="attributes")SecurityAttributes[] attributes,
          @WebParam(name="userName")String userName,
          @WebParam(name="date")Date date,
          @WebParam(name="source")Integer source
          )
          {
          StringBuffer cmd = prepareCommand(spn, attributes, date, source);

          cmd.append(");}; " );
          String[] returnValues = {};
          try {
          Object result = pit.submit(cmd.toString(), returnValues.getClass());
          returnValues = (String[]) result;
          }
          catch(Exception e) {e.printStackTrace();}

          return returnValues;

          }

          }

          the web service basically invokes a perl engine and passes a command to it. the exception however has got to do with the datatypes used by the web method, if i am right.

            Some steps I't try to make:

            1. check that you are running jboss with jdk 1.5 (sun)
            2. check that your system classpath is empty when starting jboss
            (make sure that no non jboss jabxb, jaxws,.... classes are found
            3. check that the endorsed dirs in jdk are not ... see 2.
            4. check whether jboss runs the jbossws samples
            5. when 1...4 are running check your custom class wheter it
            fullfills all jaxb requirements (probably replace it by somthhing simplier

            Hope this helps

              buddy,
              thanks a lot. i dint quite figure what the exception was though. the classpath contained some proprietary jars needed for my custom class, which i later moved into the war.
              my service is deployed successfully now.

              thanks again,
              San

                hi....I had similar issues....the same exception...truly the exception is not atall helpful to find out the cause...thanks to this post.......then i noticed in one of my classes, i was using java.sql.Date...i changed it to java.util.Date....and i could deploy the bean successfully...so santhoshitha is right may be jboss didn't have supporting jars for java.sql.Date....!
