may be there must be the transaction manager injected in the portlet, I you did not declare it. this is done in the jboss-portlet.xml, with the look at the jboss-portlet.xml of the UserPortlet for example. something like : <portlet> | <portlet-name>MyPortlet</portlet-name> | <!-- to tell jboss portal to create a transaction around the portlet --> | <transaction> | <trans-attribute>Required</trans-attribute> | </transaction> | </portlet> | may be put the transaction injection at another place. this I can't say from what you have post. hope it helps...
