java.lang.NoClassDefFoundError: sun.awt.X11GraphicsEnvironment (initialization failure)

Technote (troubleshooting)


Problem

You try to run a Java agent on a Lotus® Domino® for IBM® i (i5/OS®) server. It is failing with the following error message:

    "java.lang.NoClassDefFoundError: sun.awt.X11GraphicsEnvironment (initialization failure)"
The agent works when run on Microsoft® Windows®.

Environment

IBM i V5R4

Resolving the problem

IBM i requires that you edit or add the following line to the SystemDefault.properties file.

    java.awt.headless=true

For details, refer to the IBM i Information Center at:
http://publib.boulder.ibm.com/infocenter/iseries/v5r4/index.jsp?topic=/rzaha/nawtsystemprops.htm

You can edit the file using the following command:

EDTF STMF('/QIBM/UserData/JAVA400/SystemDefault.properties')

Warning: Java is case sensitive. Be sure to create the file name exactly as shown and to use all lowercase letters for the property.

Be aware that this property must be set at the system level. Creating a SystemDefault.properties file in the /home/QNOTES directory will not allow the agent to run.
