Hi Pradeep
Possibly try to delete all temp internet files, etc. As Faisal mentioned, try another browser or possibly through NWBC GUI
You may need to raise a message with SAP. However, to allow you to keep working you could try the following (if error is relating to GRFN_SERVICE_MAP and not the actual functionality you need)
- Go to transaction LPD_CUST - Launchpad customizing
- Locate the Launchpad for the link in NWBC you want to use and double-click
- Navigate to the Link you wanted to launch in NWBC and double-click for Configuration information to appear
- Copy the "Application Name"
- Go to SICF transaction and enter the "Application Name" to locate the HTTP Service
- Right-click in SICF result and choose test service
- Finger's crossed error JAVA error does not appear
