[jboss-user] [JBoss AOP] - Re: NullPointerException problem and no trace of the interce

So, the example injboss is not working in your configuration of JBoss AS server?

Let's check the following steps:

- let's start with a clean server to help us tracking what is missing here (fresh installed, and you haven't edited any file of it, nor have you deployed anything)
- in this JBoss AS, remove the jboss-aop-jdk50.deployer directory of server/all/deploy
- download the latest stable version of JBoss AOP (1.5.5 GA)
- in the directory docs/aspect-framework/examples/injboss of your JBoss AOP installation, edit build.xml file, in order to set your jboss.home directory as follows:

  |  <property name="jboss.dir" value="your jboss home directory here"/>
  |  
- run one of the loadtime deployment tasks of the injboss example, like the following:

  | $ ant deploy-basic-lt-war-in-jar
  | 
- copy the appropriate jboss-aop-jdk50.deployer directory from your JBoss AOP installation to your server/all/deploy directory.
- edit jboss-aop-jdk50.deployer/jboss-service.xml, setting EnableLoadTimeWeaving with a true value, like follows:

  |       <attribute name="EnableLoadtimeWeaving">true</attribute>
  | 
- follow the instructions of the jboss-aop-jdk50.deployer/ReadMe.txt file
- copy pluggable-instrumentor.jar file (located in the lib-50 directory of your JBoss AOP installation) to the bin directory of your server
- edit your run.sh or run.bat to include -javaagent:pluggable-instrumentor.jar in the JAVA_OPTS
- start up your server on the "all" mode
- now, access the address http://localhost:8080/aopexample/index.jsp   and you should see the interceptor messages on your console.

This should work. Once you have this up and running, just replace the injboss jar by your application file in the deploy dir.
