The source code is included with the sample Enterprise Service Portal. To make complex changes to the portal, we recommend that you install a Java development environment.
The sample Enterprise Service Portal does not require any specific environment, but the procedures to develop a portal assume that you use the Eclipse platform. A servlet container is required to run the portals during development. We recommend that you use Tomcat and its Eclipse plug-in.
For information about your development environment, see the documentation for the product you are using.
