Thanks for your answer Thomas ! The shopping cart and catalog portlets looks great for my needs, but I can't find them here : http://www.jboss.org/portletswap/portlet_main.html Where can I download the source code ? The sun examples are recognized by JBoss Portal, but when I display them, I have this Exception: 11:55:32,743 ERROR [[jsp]] "Servlet.service()" pour la servlet jsp a lancé une exception org.apache.jasper.JasperException: L'uri absolue: http://java.sun.com/portlet ne peut être résolu dans le fichier web.xml ou dans les fichiers jar déployés avec cette application at org.apache.jasper.compiler.DefaultErrorHandler.jspError(DefaultErrorHandler.java:51) at org.apache.jasper.compiler.ErrorDispatcher.dispatch(ErrorDispatcher.java:409) It's maybe nothing, but I prefere to start with the shopping cart, once I'll get the source code.
