In case you need to uninstall your PowerConnect Java Application, you need to know that this is possible using a Telnet connection. So please ensure having a Telnet client and the ability to actually open a connection with it. Then follow these steps:
Logon the local system
Start Telnet Client
Connect to localhost or 127.0.0.1 using port 50008
Login using a user account with undeploy permissions. This could be administrator.
Remove the PowerConnect Java App by issuing three undeploy commands. Please use the correct order!
Undeploy the SAP PowerConnect Java UI using the command “undeploy vendor=com.powerconnect5 name=spcj_wd”
Undeploy the SAP PowerConnect Java App using the command “undeploy vendor=com.powerconnect5 name=spcj_app”
Undeploy the SAP PowerConnect database contents using the command “undeploy vendor=com.powerconnect5 name=spcj_db”
After that PowerConnect is fully removed from your SAP NetWeaver AS Java instance.
