    NotSerializableException using standalone TreeCacheAop

    Clinton Parham Newbie

      Scenario:
      Server A starts up and adds a Map to the cache using this code

      ...
      private static TreeCacheAop treeCache;
      public static synchronized TreeCacheAop getClusterCache(){
       if(treeCache == null){
       try {
       treeCache = new TreeCacheAop();
       PropertyConfigurator config = new PropertyConfigurator(); // configure tree cache.
       config.configure(treeCache, "replSync-service.xml");
       treeCache.startService();
       } catch (Exception e) {
       traceLog.fatal("Error while initializing JBoss cache", e);
       }
       }
       return treeCache;
      }
      ...
      if(Util.getClusterCache().exists("/aop/expresso/CacheManager/cacheLists")){
       cacheLists = (FastHashMap)Util.getClusterCache().getObject("/aop/expresso/CacheManager/cacheLists");
      } else {
       Util.getClusterCache().putObject("/aop/expresso/CacheManager/cacheLists", cacheLists);
       cacheLists = (FastHashMap)Util.getClusterCache().getObject("/aop/expresso/CacheManager/cacheLists");
      }
      ...
      


      When Server B starts up and executes the same code, this error appears on server A console:

      2004-09-12 22:01:22,809 ERROR [MessageDispatcher up processing thread] cache.TreeCache$MessageListenerAdaptor (TreeCache.java:2919) - failed getting the transient state
      java.io.NotSerializableException: com.jcorporate.expresso.core.cache.UnOrderedCache
      at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1054)
      at java.io.ObjectOutputStream.writeObject(ObjectOutputStream.java:278)
      at java.util.HashMap.writeObject(HashMap.java:978)
      ...

      and this error on server B console:

      2004-09-12 22:01:23,260 ERROR [main] blocks.RpcDispatcher (RpcDispatcher.java:128) - exception=java.io.NotSerializableException: UnOrderedCache
      2004-09-12 22:01:24,182 ERROR [main] blocks.RpcDispatcher (RpcDispatcher.java:128) - exception=java.io.NotSerializableException: UnOrderedCache

      The class UnOrderedCache does not implement Serializable which as I understand is not a requirement for TreeCacheAop. I do not have a jboss-aop.xml file because I'm using -Djava.system.class.loader=org.jboss.aop.standalone.SystemClassLoader. UnOrderedCache contains a few private members: couple strings, another HashMap, Logger reference etc.

      The code is running under Tomcat 4.1.24 using JDK1.4.2 and jbosscache 1.1 with aop 1.0rc1

      Any suggestions greatly appreciated!

          ... one additional comment. 'cachelists' in the code sample is a Map instance to which an UnOrderedCache instance is added

            You will still need jboss-aop to declare your object, UnOrderedCache, to be aspectized. Otherwise, aop will treat it as a regular object of which requires Serializable, and furthermore will not breakdown the object graph for UnOrderedCache.

              Thanks for your feedback but I'm still having the same problem.

              I'm assuming that 'aspectized' means adding UnOrderedCache to the jboss-aop.xml. This is the contents of the file (I copied it to the root of my classes folder):

              <?xml version="1.0" encoding="UTF-8"?>
              <aop>
               <prepare expr="field(* $instanceof{com.jcorporate.expresso.core.cache.UnOrderedCache}->*)" />
              </aop>


              Another attempt at running resulted in the same errors I listed above.

              Where am I going wrong?

                Forget about the map and list. Why don't you do a putObject on UnderedCache to see if it gets replicated correctly?

                  Same problem. Here's the updated code I'm running:
                  if(Util.getClusterCache().exists("/aop/expresso/CacheManager/cacheLists")){
                   } else {
                   Util.getClusterCache().putObject("/aop/expresso/CacheManager/cacheLists", new UnOrderedCache());
                   }


                  I set logging to DEBUG. Here are the results for Server A:

                    Well, the log says obj is non-advisable:

                    Are you sure your jboss-aop.xml is in the class path? Under the distro, you can run the aop example. Make sure that works first. For example,

                    sh build.sh run.aopc.examples -Dtest=org.jboss.test.cache.test.standAloneAop.AopLocalTest

                      If not finding jboss-aop.xml is the problem then maybe you can tell me how I'm supposed to correctly specify the location of jboss-aop.xml? I've already tried the following:
                      - creating a WEB-INF/classes/META-INF folder and copying jboss-aop.xml to it
                      - copying jboss-aop.xml to the WEB-INF/classes folder
                      - adding -Djboss.aop.path=...path...\jboss-aop.xml to the JAVA_OPTS environment variable that is used by the Tomcat startup script

                        Some more info...

                        I've even reverted to using the org.jboss.test.cache.test.standAloneAop.Person instead of UnOrderedCache (setting -Djboss.aop.path=...path...\jboss-aop.xml) and I still get the same errors.

                        These jars have been added to the tomcat/common/endorsed folder to support org.jboss.aop.standalone.SystemClassLoader:

                        commons-collections.jar
                        concurrent.jar
                        javassist.jar
                        jboss-aop-jdk15.jar
                        jboss-aop.jar
                        jboss-common.jar
                        junit.jar
                        log4j-1.2.7.jar
                        qdox.jar
                        trove.jar
                        xalan_2_6_0.jar
                        xercesImpl.jar
                        xml-apis.jar


                        Help!

                          If you are running under Tomcat, it'd be best to use aopc to pre-compile your advisable object. Check into the example in build.xml of aopc. That way, at least, you take the class loader out of the picture.
