Re: BIRT 2.0 Reporting Tool

[Sarah Dewar <Sarah.Dewar@xxxxxxxxxx>]

   Thanks Mark,

   Maybe I should have specified that I have already added
   java.awt.headless=true as a JVM argument. I am also vaguely aware that
   certain awt classes still don't like running properly in a headless
   environment and as far as I can tell this shouldn't be a problem when
   running BIRT.

   Thanks for you suggestions,
   Sarah

   I have not tried BIRT yet but I spent some time a year ago getting another
   report solution working in WebSphere.  The basic problem with all of these
   tools is that in order to generate graphics on the fly they use some core
   Java classes that require AWT.  OS/400 does not have AWT support by
   default.

   WAS 6 uses Java 1.4, and starting with java 1.4 you can set a property
   named java.awt.headless=true.  This is a JVM property so you have to set
   it in the area of WebSphere where you can specify JVM startup properties.
   WebSphere would have to be stopped and restarted to pick up the property.

   Once this property is set, the charts *might* work.  I qualify it, because
   there are some things that the code has to do work properly in headless
   AWT.  Most tools are aware of this property now and code their graphics
   routines so that it will work in this environment.

   If it does not work, then OS/400 has a different way you can setup the JVM
   so that an AWT environment is available.  It requires running VNC on the
   server and it then uses the VNC server to provide a graphics environment.

   There is documentation on all of this in the IBM docs.  Search for
   java.awt.headless and you should fine stuff.
