Error when processing your request
What has happened?
The URL http://sapserver:8001/sap/bc/webdynpro/sap/zz_sampleapp was not called due to an error.
Note
The following error text was processed in the system DM0 : Die URL enthält keine vollständige Domainangabe (sapserver statt sapserver.).
The error occurred on the application server sapserver_DM0_01 and in the work process 0 .
The termination type was: RABAX_STATE
The ABAP call stack was:
Method: CHECK of program CX_FQDN=======================CP
Method: LATE_CONSTRUCTOR of program CL_WDR_UCF====================CP
Method: HANDLE_REQUEST of program CL_WDR_UCF====================CP
Method: IF_HTTP_EXTENSION~HANDLE_REQUEST of program CL_WDR_MAIN_TASK==============CP
Method: EXECUTE_REQUEST of program CL_HTTP_SERVER================CP
Function: HTTP_DISPATCH_REQUEST of program SAPLHTTP_RUNTIME
Module: %_HTTP_START of program SAPMHTTP
What can I do?
If the termination type was RABAX_STATE, then you can find more information on the cause of the termination in the system DM0 in transaction ST22.
If the termination type was ABORT_MESSAGE_STATE, then you can find more information on the cause of the termination on the application server sapserver_DM0_01 in transaction SM21.
If the termination type was ERROR_MESSAGE_STATE, then you can search for more information in the trace file for the work process 0 in transaction ST11 on the application server sapserver_DM0_01 . In some situations, you may also need to analyze the trace files of other work processes.
If you do not yet have a user ID, contact your system administrator.
