Issue/Introduction

 When accessing CEM Analysis Graph, the browser returns this error:

"HTTP ERROR 500

Problem accessing /wily/cem/tess/app/biz/defectReport.html. Reason:

Could not initialize class sun.awt.X11GraphicsEnvironment"

Cause

 Sun/Oracle Solaris has a option to tell if the code is running in Headless mode, and avoid using GUI components if having no display.

 The setting is telling it not to expect any GUI.

Environment

Introscope from 9.7 onward.

Resolution

 To resolve the issue, set- Djava.awt.headless to true inside your JVM arguments.

 If using EMService.conf (running as a service), add the row "wrapper.java.additional.1=-Djava.awt.headless=true"

 If using IntroscopeEnterpriseManager.lax file, add or change to true at the end of JVM arguments "-Djava.awt.headless=true".

 Do this for each Collector and MOM and restart the cluster.
