Question

I have Weblogic 10.3.5 installed. I deployed a WAR with JSF 2.0 and JSTL 1.2 on the server. But I need EL 2.2 functionality as well. What JARs do I need? It’d be great if someone can point me to a step-by-step guide from scratch as I’ve been trying to set this up for hours with no luck.

Answer 1

Easiest is to drop jboss-el.jar, which is an EL 2.1 compatible implementation offering the same features as EL 2.2, in /WEB-INF/lib and tell the JSF implementation to use that EL implementation instead. How to do that depends on the JSF implementation being used. In case of Mojarra, you need to add the following context parameter to the web.xml:

<context-param>     
    <param-name>com.sun.faces.expressionFactory</param-name>
    <param-value>org.jboss.el.ExpressionFactoryImpl</param-value>   
</context-param>

And in case of MyFaces, it’s the following context parameter:

<context-param>     
    <param-name>org.apache.myfaces.EXPRESSION_FACTORY</param-name>
    <param-value>org.jboss.el.ExpressionFactoryImpl</param-value>   
</context-param>
