Cepter comes pre configured in the default installation with the developer portal - no additional installation is needed.
Starting developer portal
The developer portal is started using a Ceptor launcher. In the default installation it comes with its own launcher file pp/config/pp_launch_developerportal.xml which can either be used to start up the developer portal by it self on its own server or the launch configuration can be copied into the pp/config/pp_launch.xml and it can be started with the rest of Ceptor.
