Putting it in jre\lib\ext is a bad idea (tm).

Tomcat 6.0.x implements JSP 2.1 and EL 2.1 ExpressionFactory.newInstance() was introduced in EL 2.2. It is *not* part of EL 2.1 in any way whatsoever. It was first suggested in a proposed maintenance release for EL 2.1 but that maintenance release whet on to become EL 2.2. This appears to have confused a number of folks into thinking it was/will be part of EL 2.1. To use that method you need to use Tomcat 7.0.x Mark --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
