The Java EE 6 Tutorial

Modifying the Java EE Application

The GlassFish Server supports iterative development. Whenever you make a change to a Java EE application, you must redeploy the application.

ProcedureTo Modify a Class File

To modify a class file in an enterprise bean, you change the source code, recompile it, and redeploy the application. For example, if you want to change the exchange rate in the dollarToYen business method of the ConverterBean class, you would follow these steps.

To modify ConverterServlet, the procedure is the same.

  1. Edit and save the file.

  2. Recompile the source file.

    • To recompile in NetBeans IDE, right-click the converter project and select Run.

      This recompiles the file, replaces the old class file in the build directory, and redeploys the application to GlassFish Server.

    • Recompile using Ant:

      1. In a terminal window, go to the tut-install/examples/ejb/converter/ subdirectory.

      2. Type the following command:

        ant all

        This command repackages, deploys, and runs the application.
