JasperException in Tomcat 5.0 and above but not in 4.1
Hello everybody.
We are still using Tomcat 4.1 and JDK 1.4.2 for a web application.
I'm trying to modernize this now and switch to Tomcat 5.x or 6 and
JRE/JDK 1.6 (Java 6).
While I was successful with Tomcat 4.1 and JDK 1.6, whenever I try to
use Tomcat 5.x or 6, I receive error messages like below, when pushing a
button (which will call a new page) in most of our "wizard" dialogs.
I changed web.xml to refer to web-app version 2.4 (.../web-app_2_4.xsd).
The error messages look like this:
org.apache.jasper.JasperException:
/wizard/manualAssignment/assignOrder.jsp(76,0) The name attribute of the
jsp:param standard action does not accept any expressions

org.apache.jasper.compiler.DefaultErrorHandler.jspError(DefaultErrorHandler.java:39)

.....
When I look into that file (assignOrder.jsp) there is - in line 77 -
after an <jsp:include ...> in line 76 a
<jsp:param name="<%= [some variable] %>" value="<%= [some expression ] %>"/>
Isn't this possible in Tomcat 5 and above?
Why?
I found some spec for jsp:param where it was explicity stated,
that "value" can be an <%= %> expression, but "name" cannot ... for JSP
1.2 which was used by Tomcat 4.1.
So is Tomcat 5.x and above just more strict in checking this?
Is there a way to tell Tomcat 5.x/6 to be "compatible" to Tomcat 4.1 (be
less strict)?
Thanks for any help!
With kind regards,

This seems likely. A lot of things became more strict in Tomcat 5.x...
lots of little details that were allowed but didn't follow the
specification were "fixed".

My guess is that this is not possible. You might consider asking on the
Tomcat-dev mailing list if this would be a reasonable configurable
setting -- something like "strictServletSpecificationAdherence=false" or
something like that. My guess is that the request will be rejected,
though, since Tomcat is supposed to be the reference implementation for
the specification.

Henkel-
web.xml will need to map xsd to some known mime-type e.g.
<mime-mapping>
<extension>xsd</extension>
<mime-type>text/xml</mime-type>
</mime-mapping>
Also I would look at
ValidateVisitor.visit(Validator.java:423)
for any expressions which you are currently not handling
(Velocity/Freemarker comes to mind)
