'No X11 DISPLAY' Exception running 5.4 on Linux

bernd_ruecker — Fri, 01 Apr 2011 08:54:32 GMT

We tested the current 5.4 tag on our production Linux machine (without X) and got the following exception when trying to access any web app, anybody any idea what that is and how we can disable it? The problem first occured with 5.4, 5.2 did work…javax.servlet.ServletException: Servlet.init() for se

Hi all,

in order to solve the issue, I defined the logger:


<logger name="org.springframework.extensions.webscripts.ScriptDebugger">
  <level value="info" />
</logger>

I added this logger to the log4j.xml in the WEB-INF/classes-folder of the four web-apps:

activiti-cycle

activiti-rest

activiti-probe

activiti-explorer

I even defined a log4j.xml in the ${TOMCAT_HOME}/conf.

Nothing changed. I still get the BeanInstantiation-Exception and the resulting headless-Exception.

Is there anything else I have to do? Maybe you have another advice for me?

Best Regards,

Gerardo

PS: The root-logger of the activiti-explorer, -cycle, -probe was already assigned to log-level=WARN. The ScriptDebugger should already be affected by the root-logger, shouldn't it. And because WARN is lower than DEBUG the scriptDebugger-Bean should not be instantiated in the first place. Did I miss something?

Gerardo,

I'm also puzzled by this, the debugger shouldn't be started in the first place…

Hi Frederik.

In the meanwhile we found the root source: A log4j.jar in the tomcat lib (required by a JIRA deployed on the server as well) caused no log4j configuration being read from the places we expected. Then the default was DEBUG, which caused this bug to be fired. Seems we need a dedicated TOmcat for it (on JBoss the webapps are still not running)…

Thanks for your help!
Cheers
Bernd

Will try it myself to make out what's the reason.
