PDP001I – MSG Exception in thread "main" java.lang.InternalError: Can't connect to X11 window server using ':0.0' as the value of the DISPLAY variable.

Phase: Portal installation and configuration

Area: prerequisites

Extended description:
When trying to execute the Setup Manager installer program (install.sh) to start the WebSphere Portal Server install, the Linux screen which we telnetted to displayed a Java error message: “Can’t connect to X11 window requires an X11 window to run.”

Diagnosis and solution:
Setup Manager requires an X11 window to execute because it has a GUI interface. For our Linux for zSeries installation, we exported our Linux for zSeries DISPLAY variable to our workstation’s IP address with the export DISPLAY=9.117.77.9:0.0 command. We then started KDE with the startkde & command from Linux for zSeries.

On our workstation, we started an X11 window software program called Exceed (by Hummingbird), with the communications setting set to PASSIVE. After Exceed started with our Linux for zSeries settings, we opened a terminal window within Exceed and started the Setup Manager installer program again. This time, Setup Manager started successfully.
