Hey Guys

Im running BIRT viewer on Tomcat
i can run a basic report e.g. data displayed on a table

BUT when i run a pie/bar chart i get a stack trace..the app doesnt let me copy the stack trace but it is similar to below
i created the chart in eclipse throught the plugin, would i be missing jars or something?????

SEVERE: An error happened while running the report. Cause:
java.lang.NullPointerException
