How to run a application client in jboss?

Question

Hi guys i'm new to EJB and may have some qns to ask.
I have create ejb java files, compile and package it as jar. Next i also create the .jsp pages and package it as war. I package the war and jar together with the xml files for deployment. The file works.
Now i create a java file as an application client along with the application-client.xml file. Next i jar both the class and xml files together.
Now , how am i going to run the client class file to produce the results since its jar up. I using jboss 4.0 to run the application.
thanks

Your J2SE client code should simply look up the required EJB homes using JNDI, and use the client interface to execute the EJB code. The example interfaces ejb.interfaces.SimpleHome and ejb.interfaces.Simple need to be packaged into the client JAR and placed in the classpath of test.java
Example:
import javax.ejb.EJBException;
import javax.naming.InitialContext;
import javax.naming.NamingException;
import javax.rmi.PortableRemoteObject;
import ejb.interfaces.SimpleHome;
import ejb.interfaces.Simple;
public class test {
    public static void main(String[] args) {
        try {
             InitialContext ctx = new InitialContext();
             SimpleHome home = PortableRemoteObject.narrow(ctx.lookup("ejb/Simple"), SimpleHome.class);
             Simple simple = home.create(); // or findByPrimaryKey(), etc.
             simple.aMethod();
        } catch (NamingException ne) {
            // unable to look up SimpleHome
        } catch (EJBException ejbe) {
           // generic EJBException, maybe something went wrong with Simple?
        } catch (ClassCastException cce) {
           // SimpleHome was of the wrong type
}I may have screwed up the JNDI lookup, as I might not be getting the context correctly, but I usually don't call EJB code from the command line. If I'm wrong, the only thing that will change is that ctx will have to be initialized differently. The rest should work the same.
