    POJO Cache failing on weblogic 11g managed servers

    pb2012

      Hi

       

      I have set up Pojo cache to work with weblogic server 11g.

      I have annotated and instrumented the classes as mentioned in user guide.

       

      The Pojo cache attach/find works well when I deploy the application on weblogic admin server.

       

      But when I deploy the application on any managed servers in the same weblogic domain, I get the following exception:

      java.lang.NullPointerException

      at org.jboss.aop.Domain$1.run(Domain.java:124)

      at org.jboss.aop.Domain$1.run(Domain.java:121)

      at org.jboss.aop.Domain.getDomainName(Domain.java:119)

      at com.hp.ws.business.session.WsSession$WsSessionAdvisor.(WsSession$WsSessionAdvisor.java)

      at com.hp.ws.business.session.WsSession.(WsSession.java)

       

      I am using jbosscache-pojo-3.0.0.GA and weblogic 11g

       

      Any help is highly appreciated.

          Further to my above question, I checked into the weblogic managed server log file, and found the following detailed error:

          I downloaded the latest version of jboss-aop.jar and re-instrumented the classes,
          now I am getting another exception only on the managed weblogic server instances.
          I find no issues with the same application deployed on weblogic Admin Server running on the same domain.

          This is really confusing to me, can anyone please help.

            Hello,

             

            has anyone solved this problem?

            I have the same error message at exactly the same line.

            I am using jboss-aop.2.1.8.GA.

            I am using the jboss-pojo-cache and reinstrumented all my classes using the new jboss-aop.

            There is no other aop package in my classpath and i have included all of the jars included in the distribution into my ear APP-INF/lib directory.

             

            I am trying to upgrade my application from WebLogic 10.3.0 to WebLogic 10.3.6.

            The application is productive for more than 3 years.

             

            My environment is WebLogic 10.3.6, JDK 1.6_29

            The Pojo-Cache ist the 3.0.0.GA, latest release.

             

            Has anyone a solution for this?

             

            Regards

            Edmund

              I have found the reason for this exception by myself.

              The Exception is fired because the JRockit 1.6_29 returns a null of the method invocation clazz.getDeclaringClass() in JoinPointGenerator.findAdvisedField(......);

              After I changed to the Sun JDK 1.6_29 everything works fine and clazz.getDeclaringClass() returns a non null value.

               

              Regards

              Edmund
