[jboss-user] [Installation, Configuration & DEPLOYMENT] - Error Instantiating ExpressionFactory

I'm using richfaces and spring on jboss. I wanted to switch to jboss-EL, so I added: | <context-param> | <param-name>com.sun.faces.expressionFactory</param-name> | <param-value>org.jboss.el.ExpressionFactoryImpl</param-value> | </context-param> | to web.xml Howerver when I start server now I got: | 12:25:50,046 FATAL [config] Error Instantiating ExpressionFactory | java.lang.ClassNotFoundException: No ClassLoaders found for: org.jboss.el.ExpressionFactoryImpl | at org.jboss.mx.loading.LoadMgr3.beginLoadTask(LoadMgr3.java:212) | at org.jboss.mx.loading.RepositoryClassLoader.loadClassImpl(RepositoryClassLoader.java:514) | at org.jboss.mx.loading.RepositoryClassLoader.loadClass(RepositoryClassLoader.java:408) | at java.lang.ClassLoader.loadClass(ClassLoader.java:252) | at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:320) | at java.lang.Class.forName0(Native Method) | at java.lang.Class.forName(Class.java:169) | at com.sun.faces.config.ConfigureListener.installExpressionFactory(ConfigureListener.java:1521) | at com.sun.faces.config.ConfigureListener.registerELResolverAndListenerWithJsp(ConfigureListener.java:1540) | at com.sun.faces.config.ConfigureListener.contextInitialized(ConfigureListener.java:403) | at org.apache.catalina.core.StandardContext.listenerStart(StandardContext.java:3854) | at org.apache.catalina.core.StandardContext.start(StandardContext.java:4359) | at org.apache.catalina.core.ContainerBase.addChildInternal(ContainerBase.java:761) | at org.apache.catalina.core.ContainerBase.addChild(ContainerBase.java:741) | at org.apache.catalina.core.StandardHost.addChild(StandardHost.java:553) | I even added jar with jboss-el to lib folder and I can call it in Java code.
