    treecacheaop jboss deployment

    sean blood Newbie

      Hi,

      TreeCacheAop seems perfect to handle distribution for our application, I'm trying to put together a demo ear deployment to JBOSS 4.0.2 with a webwork war deployment chatting to a dao thats accessing the TreeCacheAOP. I couldn't get the aspects instrumenting at loadtime went through all the docs but nothing worked. So i've settled on a compile time aspect build. Thats all fine. The problem is i deploy the ear, i put a couple of objects into the cache, it works fine on one node, i try to fire up another instance of jboss and a when i try to acess the cache on the other node I get
      java.lang.IllegalArgumentException: java.io.InvalidClassException: org.jboss.cache.GlobalTransaction; local class incompatible: stream classdesc serialVersionUID = 4866921742522915574, local class se
      ialVersionUID = 8011434781266976149
      at org.jgroups.Message.getObject(Message.java:224)
      at org.jgroups.blocks.RpcDispatcher.handle(RpcDispatcher.java:203)

      I haven't been able to find an example ear deployment of TreeCacheAOP that shares a cache between 2 nodes something like that might be helpful.
      I'm not even sure if i'm accessing the Cache correctly in Jboss must it be configured as an MBean service and must i be looking up the Mbea service to access the cache.

      currently using the example standalone method for accessing the cache from the Dao bundled in the war deployment

      TreeCacheAop cache;
      String key = "/aop/person";
      public PersonDao() throws Exception{
      try {
      cache = new TreeCacheAop();
      PropertyConfigurator config = new PropertyConfigurator();
      config.configure(cache, "META-INF/replSync-service.xml"); // read in generic replSync xml
      cache.startService();
      } catch (Exception e) {
      e.printStackTrace();
      }
      }
      public void createPerson(String name, int age)
      {
      Person p = new Person();
      p.setName(name);
      p.setAge(age);
      p.setAddress(new Address());
      try {
      cache.putObject(key + "/" + p.getName(), p);
      } catch (Exception e) {
      throw new RuntimeException(e);
      }
      }

      public void removePerson(String name)
      {
      try {
      cache.removeObject(key + name);
      } catch (Exception e) {
      e.printStackTrace();
      throw new RuntimeException(e);
      }
      }

      public Object getPerson(String name)
      {
      try {
      return (Person) cache.getObject(key + "/" + name);
      } catch (Exception e) {
      throw new RuntimeException(e);
      }
      }

      I'm completely stuck any help at all would be greatly appreciated
