Modifying 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.

  1. Edit and save the file.

  2. Recompile in NetBeans IDE by right-clicking the converter project and selecting Run.

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

  3. 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.

To modify ConvererServlet the procedure is the same as that described in the preceding steps.
