JChart does not work with ICEFaces project generated with seam-gen, java.lang.NoClassDefFoundError: org/krysalis/jcharts/Chart
------------------------------------------------------------------------------------------------------------------------------

                 Key: JBSEAM-2851
                 URL: http://jira.jboss.com/jira/browse/JBSEAM-2851
             Project: JBoss Seam
          Issue Type: Bug
          Components: Tools
    Affects Versions: 2.1.0.A1
         Environment: JBoss-4.2.2 GA, JBoss Seam 2.1.0.A1, MacOS X
            Reporter: Nicolas Martignole
            Priority: Minor


I created a new project using seam-gen tools on a new project. 

During the seam setup phase, I specified the latest version of ICEFaces.
Everything went well and the default pages generated with seam-gen works properly.

I tried to insert the JCharts component from ICEFaces to draw a simple 3D Pie Chart
with the following code in home.xhtml

 <ice:form>
            <ice:panelGrid columns="2" columnClasses="leftMenu, leftMenu" rendered="#{identity.loggedIn}">

                <ice:outputChart type="pie3d"
                                 chartTitle="Network Health"
                                 labels="OK,WARN,ERROR,FATAL"
                                 data="80,10,5,5"
                                 colors="green,yellow,orange,red"
                        />
            </ice:panelGrid>
  </ice:form>

I did a "seam restart" and I get the following exception in JBoss stack

I managed to fix the issue by
- copying krysalis-jCharts-1.0.0-alpha-1.jar from ${icefaces.home}/lib to myproject/lib folder
- updating my build.xml in the EAR target, by adding an " <include name="lib/krysalis-jCharts-1.0.0-alpha-1.jar"/>" 
  in the EAR target in the fileset

I don't know very well seam-gen but it seems that it's a small bug
in one of the template build.xml defined in seam-gen folder.

Hope it will help someone
