Within Rubix we have a buildserver for the Oracle/Java developers. The server is configured in Amazon EC2 and runs on Ubuntu configured with Tomcat, Jenkins and Nexus. For standardisation and us moving to the Amazon EC2 cloud we wanted to move the Tibco builds to  the same server.

So after installing the necessary Tibco BusinessWorks 5 software on the server, moving all the source over to Linux we tried running our first Tibco build using Jenkins and the exec-maven-plugin to execute buildear.sh. Sadly it resulted in this error message:

Starting up...
java.lang.InternalError: Can't connect to X11 window server using '' as the value of the DISPLAY variable.
at sun.awt.X11GraphicsEnvironment.initDisplay(Native Method)
at sun.awt.X11GraphicsEnvironment.access$200(Unknown Source)

There seems to be a (known) bug in the Tibco BusinessWorks buildear which “sometimes” requires a graphical interface when ran from the shell. In our situation this only seemed to occur when projects had XSDs imports in a used libraries.

The solution is to configure Jenkins to use XVFB plugin and emulates a “dumb” framebuffer using virtual memory.

Thanks to collegues Roel, Maarten, Rubén and Anthony for resolving this issue.
