    pojocache-aop.xml doesn't work in jboss AS 5.1

    Frank Cheng Newbie

      I am trying to follow the tutorial of jboss-cache-pojo-tutorial to make PojoCache working in Jboss AS 5.1. I copied replSync-service.xml to C:\jboss-5.1.0.GA\server\all\deploy\cluster\jboss-cache-manager.sar\META-INF. Then copied pojocache-aop.xml to C:\jboss-5.1.0.GA\server\all\deploy, and added a VM argument  -Djboss.aop.path="C:\jboss-5.1.0.GA\server\all\deploy\pojocache-aop.xml". Jboss started successfully on all mode, the pojoCache can be started, but when calling cache.attach, it throws exception complaining Person object hasn't been instrumented even though Person class is annoted as Replicable. Here is the stacktrace:

      Looks like jboss couldn't instrument the object using pojocache-aop.xml. Any ideas?

          Try this:

           

          use  server/all   with the following

           

          1:- Edit the  C:\jboss-5.1.0.GA\server\all\conf\bootstrap\aop.xml  in LINE no-72:  <property name="enableLoadtimeWeaving">true</property>

          2:-   CopyC:\jboss-5.1.0.GA\server\all\deployers\jboss-aop-jboss5.deployer\pluggable-instrumentor.jar   to C:\jboss-5.1.0.GA\bin

          3:-  EditC:\jboss-5.1.0.GA\bin\run.conf.bat file:LINE N0=-50 type : set   “JAVA_OPTS=%JAVA_OPTS% -javaagent:pluggable-instrumentor.jar”
          4:-  Copy pojocache-aop.xml to C:\jboss-5.1.0.GA\server\all\deploy

           

          That's all

           

           

          Cheers!
