Have the simplest example, a stateless bean TestBean:
| public class TestBean implements SessionBean {
| public void ejbCreate() throws CreateException {
| }
|
| public void setSessionContext(SessionContext sessionContext) throws
EJBException {
| }
|
| public void ejbRemove() throws EJBException {
| }
|
| public void ejbActivate() throws EJBException {
| }
|
| public void ejbPassivate() throws EJBException {
| }
|
| public void sayHello()
| {
| System.err.println("Hello AOP world");
| }
| }
|
All this gets packet into TestEjb.jar which explored looks like this
META-INF which contains only EJB related descriptors but no jboss-aop.xml
com/balamaci/proiect
-TestHome.class
-TestBean.class
-RemoteTest.class
-SimpleInterceptor.class
The SimpleInterceptor class contains:
| public class SimpleInterceptor {
| public String getName() {
| return "SimpleInterceptor";
| }
|
| public Object invoke(Invocation invocation) throws Throwable
| {
| try
| {
| System.err.println("<<< Entering SimpleInterceptor");
| System.out.println("<<< Entering SimpleInterceptor");
| return invocation.invokeNext();
| }
| finally
| {
| System.err.println(">>> Leaving SimpleInterceptor");
| }
| }
| }
|
got the client that just does
| try
| {
| Properties env = new Properties();
| env.setProperty(Context.INITIAL_CONTEXT_FACTORY,
"org.jnp.interfaces.NamingContextFactory");
| env.setProperty(Context.PROVIDER_URL, "localhost:1099");
| env.setProperty("java.naming.factory.url.pkgs",
"org.jboss.naming:org.jnp.interfaces");
| Object obj = ctx.lookup("TestEJB");
| TestHome home = (TestHome)
javax.rmi.PortableRemoteObject.narrow(obj,TestHome.class);
| RemoteTest test=home.create();
| test.sayHello();
| }
| catch(Exception e)
| {
| e.printStackTrace();
| }
|
|
After starting a default instance of jboss i copy the jboss-aop.xml in the
deploy directory. The jboss-aop.xml looks like this
| <?xml version="1.0"?>
| <aop>
| <bind pointcut="execution(public void
com.balamaci.proiect.TestBean->sayHello())">
| <interceptor class="com.balamaci.proiect.SimpleInterceptor"/>
| </bind>
| </aop>
|
After that i copy the TestEjb.jar in the deploy directory and after it says
it's been deployed, i run the client.
The ugly part is that instead of printing something nice it gets all of this:

The injboss example works fine though.
Did someone else encounter this problem? Am i taking the wrong steps to
deployment?
Thanks!
