pzAppConfig Execution Error on page pydisplayharness of class Data-Portal
I have a customer evaluating Pega 7.21 and they received the following error "pzAppConfig Execution Error on page pyDisplayHarness of class Data-Portal"
After looking at the logs the customer found:
The error message in the JBoss log is “06:03:06,422 INFO [stdout] (Dispatcher-Thread-95) java.awt.AWTError: Can't connect to X11 window server using ':0.0' as the value of the DISPLAY variable.”
Per the instructions in the installation document I had included the option “-Djava.awt.headless=true” but it may not have been applied correctly. I’ve updated the JAVA_OPTS and restarted the server.
Has anyone seen this issue? If so, what are the steps to troubleshoot or fix?

Hi,
This is an expected behavior when user do a preview on a section which contains a field using a JSP code control. When user runs a use case which invokes the same section during the runtime, the error does not occur. Data is populated correctly in the UI.
