which would then call the act

Answer 1

As mentioned in other answers, you need to add the el-api-2.2.jar to your Tomcat server's lib folder, and the el-impl-2.2.jar to your WEB-INF/lib folder.

Other answers mention deleting jasper or creating custom implementations of ExpressionFactoryImpl. That might work, but you shouldn't need to do that.

You just need to override the expression factory implementation using org.apache.myfaces.EXPRESSION_FACTORY on MyFaces or com.sun.faces.expressionFactory on Mojarra.

    org.apache.myfaces.EXPRESSION_FACTORY
    com.sun.el.ExpressionFactoryImpl

  
    com.sun.faces.expressionFactory
    com.sun.el.ExpressionFactoryImpl
