I edited the property "UseStrictMode" in this file jboss-portal.sar/portal-wsrp.sar/META-INF/jboss-service.xml and set its value from "true" to "false" everything seemed to work! I am able to see a jboss portlet in sharepoint. Here is my configuration file as an example if anyone else is trying to do this: <Configuration xmlns="http://schemas.microsoft.com/office/sps/2005/WSRP/Configurati... | | <Producer Name="JBoss Portal" AllowScripts="true"> | <ServiceDescriptionURL>http://localhost:8080/portal-wsrp/ServiceDescriptionService</ServiceDescriptionURL> | <RegistrationURL>http://localhost:8080/portal-wsrp/RegistrationService</RegistrationURL> | <MarkupURL>http://localhost:8080/portal-wsrp/MarkupService</MarkupURL> | <PortletManagementURL>http://localhost:8080/portal-wsrp/PortletManagementService</PortletManagementURL> | | </Producer> | </Configuration> Thanks chris for your help View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4194099#...
