Re: Testing JSF 1.2 Managed Beans vs. JSF 1.1

Ok Matt I ran into a similar problem in a testmigration of an old
project to myfaces 1.2.

Following, make sure that you are on a current container version
implementing the newest jsp and servlet apis (in my case tomcat running
on java 5)
then remove all traces to the jsp-api and any el-implementation (however
commons-el has to be still there if you use tomahawk otherwise you will
get an error, tomahawk references commons-el logger somewhere)

if done it should work.

The main problem with the migration is that old installs relied on a
hogde podge of various deps into el implementations and servlet specs,
1.2 is pure jee5 so any older version of the servlet spec or el or jsp
in your runtime classpath is a source of possible problems.
