Setting up a headless environment with Tomcat to display flashboards

If you use a terminal to reach a headless UNIX system where you have installed the web server and Mid Tier, you might receive error messages when accessing flashboards through a browser. To make sure that flashboards work from a headless UNIX environment, you must set Java VM options on the servlet engine that controls Mid Tier.

To set .Java VM options on the servlet engine

1. In the catalina.sh file, add the following options for JAVA_OPTS near the top of the file:
   • -Djava.awt.headless=true

   • -Dsun.java2d.fontpath= sdkInstallDirectory/JavaHomeFolder/lib/fonts

     Example

     JAVA_OPTS="-Djava.awt.headless=true -Dsun.java2d.fontpath=/usr/Java/JavaHomeFolder/lib/fonts"

2. Restart Restart Tomcat for this change to take effect.

Use a similar procedure to add VM options to other servlet engines. See your respective server vendor's documentation for information about configuring Java options.
