If you are using JBoss Portal 2.6.5 you must define the ServletContextProvider in this way: | <init-param> | <name>ServletContextProvider</name> | <value>org.jboss.portal.portlet.bridge.JBossServletContextProvider</value> | </init-param> | In this version of JBoss the package of the class implementing org.apache.portals.bridges.common.ServletContextProvider is different than the previous version: the new package is org.jboss.portal.portlet.bridge.
