Answer 1

You can use JBoss EL.

It's an implementation of Expression Language 2.1. But it has extensions to allow method parameters as in your example:

The advantage is that you only have to change your webapp and not Tomcat's lib directory.

Instructions

1. Download the latest version of Seam 2
2. Extract lib/jboss-el.jar
3. Copy it to WEB-INF/lib/jboss-el.jar

4. In your web.xml set:

   
       com.sun.faces.expressionFactory
       org.jboss.el.ExpressionFactoryImpl
   
   

See also Invoke direct methods or methods with parameters in EL.
