Abstract:

How to Access EJB on Weblogic Server 9/10 from C# Client

Use this example as a guideline to show you how to access your Enterprise Java Beans (EJB) from a .NET client, using J-Integra for .NET. This example could be deployed on BEA's Weblogic 9.1 or 10.0 Application Server.

Note: For a more detailed step-to-step instruction, please refer to this Access EJB on Weblogic 8.1 from .NET Client example.

To run the example, follow these directions:

Download the attachment below (bea_weblogic_91_http.zip), and unzip it into any folder of your choice.

Run Janetor to Configure J-Integra for .NET

Use Janetor tool open the \java_server\janet.xml configration file. All settings in Janetor should be already set, the only thing you need to do is to install your own J-Integra for .NET license before your test.

Generate a Web Application aRchive (WAR file)

In Janetor, go to "File - Export web application archive". The screenshot below shows the Export web application archive window. See the documentation for Janetor for a description of all the fields. Make sure you select the correct ejb20_basic_beanManaged_client.jar from the downloaded example. Change Output file as necessary.

How to Access .NET Event from Java

There are two ways to access .NET event from Java Clients:

Registering the event listener (Java way to access event)
Using .NET events (actual .NET events) from Java, wrapping .NET events using a delegate and an equivalent interface exposed to Java

We suggest using the first way to access .NET event, because it treats the .NET event as a normal Java event (add/remove event listener). The second way involves a wrapper class around the class using the events. It’s a little rough around the edges but it works.

Note: for the attached examples, please use Janetor tool to install your J-Integra for .NET license before your test. You can find the janet.xml for each test in \java_client directory after you unzip the attached examples.

1. Registering the event listener

Please find the attached java_csharp_event.zip for this example.

A. Write the .NET Server with event handler:

using System;
using System.Runtime.InteropServices;
using System.Collections;

namespace csharp_server
{
 public class Factory : MarshalByRefObject
 {
  private ArrayList listeners;
  public Factory()
  {
   Console.WriteLine("Factory Created...");
   listeners = new ArrayList();
  }
  public void addMyEventListener(ITestListener l) 
  {
   listeners.Ad
