Problems using Jfreechart: Unable to set display - Sun One web server
Hello-
I am unable to make the charts display on the clients machine.
In iplanet UI, in the JVM Options, I have added -Djava.awt.headless=true
The error I get is
----- Root Cause ----- java.lang.NoClassDefFoundE
The reason I believe this is because of the display setting is that I have seen similar error when I tried to do same thing in tomcat , and in tomcat when I would set the display, it would work fine.
Any thoughts. Thanks and this is urgent.

Yes, the jar files are in web-inf/lib

JFreeChart.DEFAULT_TITLE_F

add them to the app servers classpath.
That shouldn't be necessary - they are being loaded by the web app

I have put the charts.jar in web-inf/lib directory and restarted the iplanet server.
Could it be that my webserver is not able to run servlets? could you give me a simple sample servlet that i could try and make sure it works.
( i have some jsp files calling java beans and connecting to database and all that works just fine)

your servlet is getting run, it is not finding your freechart classes.
Add them to your iplanet classpath and see if that fixes it.

It must be of the web app you're running and not any other. Make sure there aren't any other jars omitted too

I am not getting a page not found.
I am getting a server error. does that mean it is finding the class files?

No it means your servlet is executing, but it cannot find a class it requires.
Did you try changing the classpath yet?

The problm was one jar file i had on server was jcommon ver9.jar but in my local, i had jcommon8.jar and some methods were deprecated and not working in version9.
I replaced the jar file with jcommon8, and all is working fine.
Thanks both for pointing me in right direction - to look at the jars.
I kept on thinking it is display issue for some reason and spent all my time finding differnet ways to set display.

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.
