Debug application code deployed on GlassFish using NetBeans ?

Posted by arungupta on June 18, 2007 at 7:31 AM PDT
One of my friends asked how to debug a Servlet deployed on
Java Application
Platform SDK Update2
.
Debugging Servlet is no different than debugging any application on the
Application Server. However

searching on java.sun.com
gave really old results. Top-level Search
functionality is missing on glassfish.dev.java.net which
hopefully will be fixed soon. Googling finally showed
Debugging
Applications
but this is again command-line. So I decided to write a short
blog describing the simple steps involved to debug a server-side application using
NetBeans/GlassFish. Application Platform SDK Update2 contains Sun Java System
Application Server 9.1 Beta2 which is equivalent to
GlassFish V2
b41d
.
  1. After you've installed GlassFish as 'Runtime' Server, then you need to
    start the Application Server in debug mode by right-clicking on the Server
    instance and selecting 'Start in Debug Mode'.





  2. This starts the Application Server on debug port 9009 and you'll see
    something similar in your NetBeans IDE:



  3. The default web page when you browse your Web project is 'index.jsp'.
    However if you need to debug your own Servlet then you need to configure it
    as the default page by right-clicking on Project, selecting Properties, Run
    category and specify the relative URL of the Servlet as shown below ('/NewServlet'
    in this case):



  4. That's all it takes to configure GlassFish in debug mode using NetBeans
    IDE. Deploy your applications on GlassFish or Application Platform SDK and
    set up break points any where ever you like in your application code. To debug your Web project,
    the simplest way is
    to right-select your project and choose 'Debug Project' as
    shown below:





    If you
    created a default Servlet using NetBeans IDE, then you can set up breakpoint
    in 'processRequest' method and watch the debug output in '
    Debugger 
    Console
    ', 'Local Variables', 'Call Stack' and much more.
