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, ICE Faces Integration 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 Caused by: java.lang.NoClassDefFoundError: org/krysalis/jcharts/Chart at java.lang.Class.getDeclaredMethods0(Native Method) at java.lang.Class.privateGetDeclaredMethods(Class.java:2395) at java.lang.Class.getDeclaredMethods(Class.java:1763) at java.beans.Introspector$1.run(Introspector.java:1265) at java.security.AccessController.doPrivileged(Native Method) at java.beans.Introspector.getPublicDeclaredMethods(Introspector.java:1263) at java.beans.Introspector.getTargetMethodInfo(Introspector.java:1129) at java.beans.Introspector.getBeanInfo(Introspector.java:387) at java.beans.Introspector.getBeanInfo(Introspector.java:159) at javax.faces.component.UIComponentBase.getPropertyDescriptors(UIComponentBase.java:167) at javax.faces.component.UIComponentBase.populateDescriptorsMapIfNecessary(UIComponentBase.java:132) at javax.faces.component.UIComponentBase.<init>(UIComponentBase.java:121) at javax.faces.component.UICommand.<init>(UICommand.java:102) at javax.faces.component.html.HtmlCommandButton.<init>(HtmlCommandButton.java:53) at com.icesoft.faces.component.ext.HtmlCommandButton.<init>(HtmlCommandButton.java:93) at com.icesoft.faces.component.outputchart.OutputChart.<init>(OutputChart.java:118) at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:39) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:27) at java.lang.reflect.Constructor.newInstance(Constructor.java:494) at java.lang.Class.newInstance0(Class.java:350) at java.lang.Class.newInstance(Class.java:303) at com.sun.faces.application.ApplicationImpl.newThing(ApplicationImpl.java:1014) ... 84 more 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
