[转]Remote Debugging with Eclipse + WebSphere 7-优快云博客

本文介绍如何通过Eclipse使用Java Debugger (jdb)进行WebSphere 7的远程调试。首先需要在WebSphere中启用调试模式，并设置监听端口8888。然后在Eclipse中配置远程Java应用连接到该端口，即可开始调试。

So far, there is still lack of WebSphere 7 plugin for both Eclipse and NetBeans IDE. However, you are able to debug your web application via Java Debugger (jdb).

Here’s a guide to show you how to remote debugging your web application in Eclipse and WebSphere via Java Debugger (jdb).

Eclipse <----> Java Debugger (jdb) <----> WebSphere 7

1. Enable WebSphere in Debug Mode

In WebSphere web console, left navigation, <script type="text/javascript"></script><script src="http://pagead2.googlesyndication.com/pagead/show_ads.js" type="text/javascript"></script><script src="http://pagead2.googlesyndication.com/pagead/js/r20110324/r20110321-2/show_ads_impl.js"></script><script></script>

1. Servers –> Server Types –> WebSphere application servers
2. Under Server Infrastructure section –> expand Java and Process Management –> Process definition
3. Under Additional Properties section –> click Java Virtual Machine
4. Checked the “Debug Mode”
5. In Debug arguments textbox, put this

-Xdebug -Xnoagent -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=8888

6. Restart WebSphere server instance.

Now, WebSphere is started in debug mode, and listening on port 8888. (Later, Eclipse will connect to this port for debugging)

2. Install or deploy web application to WebSphere

“war” your web application, install (first-time) or deploy it to WebSphere. And start your web application in WebSphere.

3. Eclipse’s Java Debugger (jdb)

In Eclipse IDE, under your project source

1. Click on “Run”, “Debug Configurations…”
2. Select “Remote Java Application”, right click and select “New”
3. Renamed a new name , e.g “WebSphere 7 Instance”
4. In “Connection Type”, select default, “Standard (Socket Attached)”
5. Host, put your WebSphere host IP
6. Port, put 8888.

7. Click on the debug button.

Now, Eclipse debugger is started and connected to port 8888.

4. Debugging, see result!

Open your favor browser, and type your web application URL. Now, Eclipse will stop at your predefined breakpoint.

Done.

Note
This Java Debugger (jdb) solution is able to apply on most of the Java Application Servers, like JBoss, WebLogic, or even in Servlet Container like Tomcat. The only problem in this method is, you have to make sure the deployed web application is synchronize with Eclipse’s debugging source code.
