web.xml is not meant, but jboss-web.xml instead - just create one. It resides in WEB-INF too. Try this one:<?xml version="1.0" encoding="UTF-8"?> | <portlet-app> | <portlet> | <portlet-name>UserAdminPortlet</portlet-name> | <transaction> | <trans-attribute>Required</trans-attribute> | </transaction> | </portlet> | <service> | <service-name>UserModule</service-name> | <service-class>org.jboss.portal.identity.UserModule</service-class> | <service-ref>:service=Module,type=User</service-ref> | </service> | </portlet-app> This might help: http://docs.jboss.com/jbportal/v2.6.6/referenceGuide/html/xmldescriptors....
