Installation of jBPM 3.3.0 GA on a headless linux box

[rburnett]

Hi there,

I just tried installing jBPM 3.3.0 on a headless Linux box and it complains about not finding a X11 display variable (exact error is below)
Is there a way to install this release with out using the graphical interface?
Any suggestions would be appreciated.

Thanks!


java.awt.HeadlessException:
No X11 DISPLAY variable was set, but this program performed an operation which requires it.

Does this really work? I'd expect not, since the installer really needs something visual. In what way do you want to use jBPM? Testing the full 'server'? Otherwise you might install it on a separate box with display and use the libs.

But you've got a point there. I'll raise a jira issue for this if you report back that the solution proposed by ppc does not work

Hmmm... I forgot to also add that you get the option to generate an automatic install script at the end of the installer. So after installling locally, you can run that remotely. How? I'm not sure, please check the izpack docs for that

[kukeltje]

So I'll just file a jira issue that the reason for the automatic installscript should be documented
