JSF + tag files problem with new Tomcat
Hi,
There's a JSF webapp I maintain. It runs fine on Tomcat 6.0.18. Recently
I wanted to migrate environment to 6.0.26 but I ran into problems. Due
to lack of time I just dropped migration idea. Unfortunately the same
problem exists with Tomcat 6.0.28.
Basically, the problem is with handling JSF specific expressions from
within tag files. I don't think that use of tag files is forbidden with
JSF. But I'm not 100% sure though.
So, following code works when in use directly in JSP page:
<h:outputText value="#{app.username}"/>
But when used in a tag file it produces:
#{app.username}
There are no error messages in logs.
So, it used to work before because of some misimplementation in previous
versions. Or stopped to work now because of misimplementation in newer
versions :-)
In case someone is interested, here's the source code:

and war file

Hi Mark,
Thanks for prompt response.
It's good when you've got opportunity to learn new things!
For those who do not know about implicit.tld:

This is the reason. It is the result of fixing
https://issues.apache.org/bugzilla/show_bug.cgi?id=48668
In short, no implicit.tld has been defined for the tag library so the
spec mandates that a JSP version of 2.0 is used. JSP 2.0 doe snot
support the #{...} syntax for EL so it gets treated as template text.
Prior to the fix, Tomcat incorrectly used JSP 2.1 for implicit tag
libraries.
