can someone help me with this please. i'm developing a web app on jboss 4.2.0 where i need the setActionExpression method (for a Richfaces PanelMenuItem) from the javax.el lib. Unfortunately it's not part of the jboss libs. does anyone know where to deliver it and add it?
found libs, added libs, deployed and got following exception:
Exception sending context initialized event to listener instance of class com.sun.faces.config.ConfigureListener
java.lang.LinkageError: loader constraints violated when linking javax/el/ExpressionFactory class
