To compile and package converter using Ant, do the following:
In a terminal window, go to this directory:
Type the following command:
This command calls the default task, which compiles the source files for the enterprise bean and the application client, placing the class files in the build subdirectories (not the src directory) of each submodule. Then the default task packages each submodule into the appropriate package file: converter-app-client.jar for the application client, converter-ejb.jar for the enterprise bean JAR, and converter-war.war for the web client. The web client in this example requires no compilation. For more information about the Ant tool, see Building the Examples.
When compiling the code, the preceding ant task includes the javaee.jar file in the classpath. This file resides in the lib directory of your Application Server installation. If you plan to use other tools to compile the source code for Java EE components, make sure that the classpath includes the javaee.jar file.
