How to improve GlassFish easily -- using NetBeans 5.5

Checkout Glassfish bootstrap module as below:

% cvs -d <java.net-ID>@cvc.dev.java.net:/cvs glassfish/bootstrap
% cd glassfish/bootstrap

Checkout project: appserv-core and install/configure GlassFish Server image by running following command, more details on GlassFish builds.
% maven -Dmodules=appserv-core checkout bootstrap configure-runtime

Now we have GlassFish Application Server image, called as ${glassfish.home} in this document later as GlassFish documents. We have checked out appserv-core module in GlassFish, so we will modify the code and build the workspace using NetBeans IDE.

Open the IDE by running  <ws>/netbeans-5.5preview/bin/netbeans command. In the "Runtime" tab, you will see Tomcat and Sun Java System Application Server in the "Servers" tree, add "GlassFish" Server to test your newly installed GlassFish server from ${glassfish.home} and start the server by right clicking GlassFish Server name and select "Start" menu. You will see the server log messages in the bottom of the IDE window.

Now open project appserv-core using NetBeans 5.5 IDE from the GlassFish Workspace,  in Netbeans "File" menu, go to "Open Project.." and select "appserv-core" directory from GlassFish workspace that we checked out earlier.
Goto "src\java" source tree and select package "com.sun.enterprise.server" and double click on PEMain.java and goto line at the log message string variable: "pemain.startup.complete" (for message "Application server startup complete"). Add few messages using System.out.println statements so that it will be displayed on the output or log file.
Now right click on "Sun... glassfisher core" project and select "Build Project" from the menu, you will be able to build appserv-core project as below.

Now you can start the GlassFish Server, you should be able to see the new added output lines around the "Application server startup complete" message in PEMain.java which is the main launcher java program for GlassFish Server.

This illustrates the full IDE support of NetBeans 5.5 to improve GlassFish Server in your developement environment which provides:

• Administration - Add, Stop, Start Server Instance.
• Ease of Development - Write source code, Compile, Build, Install, Configure GlassFish workspace.
