Class EJBServiceClient

java.lang.Object
  org.globus.ogsa.client.EJBServiceClient

public class EJBServiceClient

extends java.lang.Object

After you have generated the code to expose an ejb as a grid service using "ant ejbService" this class lets you use it just like a normal ejb.
For an example "Person" ejb in a package org.good it would work like this:

String serviceUrl = "http://127.0.0.1:8080/ogsa/services/org/good/PersonHomeFactoryService/myHome";
PersonHome home = (PersonHome) EJBServiceClient.createHomeService("org.good.PersonHome", "org.good.Person", serviceUrl);
Person remote = home.create(new Integer(123));

If you want to know the url of the remote service you can call EJBServiceClient.getRemoteUrl(remote)

If you don't want to use this class the long way to do it is:

java org.globus.ogsa.client.CreateService http://127.0.0.1:8080/ogsa/services/org/someone/PersonHomeFactoryService myHome

String homeUrl = "http://127.0.0.1:8080/ogsa/services/org/good/PersonHomeFactoryService/myHome";
PersonHomeServiceLocator homeLocator = new PersonHomeServiceLocator();
PersonHomePortType homeService = locator.getHome(homeUrl);
String remoteUrl = homeService.create(new Integer(123));
PersonServiceLocator remoteLocator = new PersonServiceLocator();
Person remote = (Person) remoteLocator.getRemote(remoteUrl);
