Why am I getting java.awt.HeadlessException while launching loadtest commandline?

  • Loadtest has been installed in Linux machine
  • Create a loadtest script (ex. loadtestscript) to run the command line
  • using the following command to run the loadtest commandline
  • ./loadtest -cmd -run loadtestscript
  • Got an Error : java .awt.headlessException at java.awt.GraphicsEnvironment.checkHeadless(GraphicsEnvironment.java:207

    Could you paste the entire console log with the exception stack trace and the Load Test version? I just checked a recent Load Test release on a machine that returns 'true' for the GraphicsEnvironment.isHeadless() Java call and runs without problems:

    [[email protected] 9.10.4]$ ./loadtest -cmd -run ../projects/run.cmd
    Parasoft Load Test
    ---------- Load Test ----------
    LoadTester stopped. [ Total Run Count = 1878; Failure Count = 0 ]

    Also what Linux are you running on?
    You could run either cat /etc/os-release or cat /etc/issue to get release info.

    Release : Red Hat Enterprise Linux Server release 6.9 (Santiago)
    ./loadtest -password XXXXXXXXX -cmd -run loadtestcmd
    The following is the detail errors log after issuing the command:

    Please contact Parasoft tech support about this issue. I let them know about your case, and they will set you up with an alternative licensing that will allow you to run Load Test on headless machines. When contacting Parasoft support please refer to this forum page.
