In many projects created from existing sources, including sample Oracle 
ADF applications the web.xml file did not use Servlet API 2.5+ 
specification, which caused the IDE to not to recognize any expression 
language, which was "hiding" substantial part of our functionality from 
the users.

The fix enables JSF-style EL ( #{...} ) regardless of the version, 
because JSF implements this EL regardless of servlet/JSP spec level.
