I'm trying to get a chart in a portlet environment using Cewolf and WebSphere Portal 5.1 and 6.
I'm getting an exception when cewolf tries to store the chart and I never get the image in the portlet. This happen using any storage (I tried with ClusterableSessionStorage, LongTermSessionStorage and TransientSessionStorage).
The stacktrace is always something like this:
Caused by: java.lang.NullPointerException
I think that is a problem with cewolf running in the portlet environment.
Any help to solve this problem?
Was you successful with the problem?
I try the framework with portlet jsr168 and have the same trouble.
