PRT Bridge Service 
The PRT Bridge gives the PRT access to the SAP J2EE Engine cluster configuration. This information is used for deploying PAR files, the JSP compiler, communication between each cluster element, managing the HTTP cache, and so on.
However, it should never be accessed directly from a portal application, but from a portal service wrapper, such as ClusterCommunication, Notification Service and SAP J2EE Engine’s HTTP service.
Use the PRT Bridge to:
· Enable the PRT Bridge logger
Set the property EnableLoging to true
· Enable the trace mode
Set the property VerboseMode to true
· Change the alias name of the portal platform
Set the property PortalServletContextName to the new required value. The default is irj

All information logs, debuging and errors information are written in a log file located in <SAPJ2eeEngine_install_dir>/cluster/serverXX/services/PRTBridge/log
