jsp - Should i use EL 2.2 with Java EE 5/Tomcat 6.0.29? Server or app upgrade? -


the questions are:

1) should use el 2.2 java ee 5 / tomcat 6.0.29?

i know works, question if there technical problem in such upgrade or if not recommended.

2) server or app upgrade?

i have app configuration in web.xml:

<context-param>     <param-name>com.sun.faces.expressionfactory</param-name>     <param-value>com.sun.el.expressionfactoryimpl</param-value> </context-param>

i followed approach because have lots of servers , not want upgrade libraries in of them. way worst upgrading in server installations?

i don't forsee issues approach. prefer above touching default server library setup. may instance overlook when installing new server instance in future. controlling libs webapp side on fine. need know you're doing. example, when supplying outdated libs, not configuring web.xml, may lead classloading collisions , result in abstract errors, manifest enough @ local dev environment anyway.
