This API is specifically designed to be useful across all sorts of use cases, so it does not contain any direct references to web APIs (servlet, JSP, or JSF).
JSP 2.1 and JSF 1.2 implementations will be able to use this API to provide _expression_ evaluation services, by implementing resolvers (for example, the managed bean facility that is currently implemented as a JSF 1.1 VariableResolver will become an ELResolver in the new API). But, you will also be able to use this API across any sort of application environment, without dragging along all the web APIs with you (as commons-el will do, because it was based on the _expression_ language in JSP 2.0).

Thanks. I am going to examine commons-el package then!
The other hint might be helpful too.
