"Error 500: Could not get property diagrammer of component form" error is displayed after opening the graphical view feature in Tivoli Dynamic Workload Console (TDWC).
Web browser displays:
Error 500: Could not get property diagrammer of component
WebSphere logs show:
SRVE0068E: Uncaught exception thrown in one of the service methods of
the servlet: /html/jsp/GraphViewerMain.jsp. Exception thrown :
javax.servlet.ServletException: Could not get property diagrammer of
component form:diagrammer ...
The TDWC server does not have the X11 window system installed. X11 is required in order to utilize the diagrammer component that TDWC uses to provide the graphical view feature.
Currently, this is not a documented requirement because all supported operating systems have this component by default. However, some operating systems have installers that allow for a "minimal" installation that may not include the required packages.
Resolving the problem
Contact your Unix system administrator to install X11 on the workstation. Then, restart the embedded WebSphere Application Server (eWAS) instance for the TDWC.
