在Jboss 4.2.3中部署了EJB3。 我们如何访问它？

Question

I deployed my EJB3 in Jboss 4.2.3. How do I access it now ? I don't see any JNDI names or anything displayed in the console. Below is the stacktrace of EJB deployment.

How do I write a client to access the method in ExtractorDAOImpl ?

Answer 1

I don't see any JNDI names or anything displayed in the console

At [myServer]:8080/jmx-console/

1) go to "service=JNDIView".

2) invoke the MBean operation: java.lang.String list()

3) it will show you the Global JNDI Namespace tree, where you can see the JNDI entries associated to your ejbs.

You will see something like this:

+- EarName | +- myEjbName | +- local

For this example the JNDI name used to lookup the local interface is "EarName/myEjbName/local"

Answer 2

JBoss 4.2.x has a JMX management web interface (jmx-console) which can list all the deployed EJBs and their JNDI names.

In any case, the standard name pattern for JBoss versions below JBoss 6 is like

EARNAME/EJB-NAME/{local,remote}

So in your case it might be:

mytestejb/ExtractorDAOImpl/local

I'm not too sure about the EJB name here, you'd have to post some code to show how you created and configured it and what interfaces you gave it.
