Hello Group!
I'm trying to upgrade to tomcat 5.0.16 but I'm having some trouble with
just
one JSP page. The pagew will not compile and the error points to this
line
in the JSP:
jsp:useBean id = LOG_KEEPER class=com.k4sv.web.LogKeeper scope =
application /
A pretty straight forward JSP line to be sure. Here is the error message:

Is there something in the new JSP spec that prevents this syntax? Am I
doing something wrong? This page compiles great under 4.1.18 by the way.
For jsp:getProperty and the others, your bean must comply with the
JavaBean specification (ie, have a no arg constructor). I think this is
indeed a change from 4.1.x (you can compare the generated code).
BTW, you can use the Jasper from 4.1.x with 5.0.x without any problems
if you don't care about JSP 2.0 for now (I suggest you care, it's nice :) ).
