Issue with JSP tags
Hello all,
I used to use JSWDK v1.0.1 earlier where my JSP code was embedded in the JSP
XML tags such as
<jsp:scriptlet> java code </jsp:scriptlet> and so on.
I realized that Tomcat v3.1 does not interpret these tags appropriately and
instead, I had to use <% java code %>! Can anyone explain this? I thought
the original tag set was part of the JSP specification and therefore must be
supported by Tomcat.
Thanks!

What you were using was a mis-implementation of the spec. The XML core
syntax and the JSP <% %> syntax were never meant to be used on the same
page, and the XML syntax is not yet required to be implemented
(especially since the spec indicates no "official" way to implement it
yet)

Nothing of the class has changed. Other classes have, but not this one.

Going out on a complete limb here, but could it possible give you this
message if one of its members had changed?

I am using Tomcat 3.1. When I replace class files for my application, and
then run it, Tomcat gives me a class cast exception on the JavaBean class
used by the JSPs - even though that class has NOT changed. Why is this
happening?
Re: Issue with the jsp:useBean

Rui,
If your bean call looks like:
<jsp:useBean id="mybean" class="myBean" />
then your getProperty call is
<jsp:getProperty name="mybean" property="username" />
then the method that is invoked inside the bean is
getUsername().
It is always been case sensitive in my experience. I think this is an
extension of the fact that Java is case sensitive.

Hiya Rui,

Yep, via reflection/introspection.

Your example is correct. You'll want to check the link below for more info
as well!

Issue with the jsp:useBean
Posted by Rui Oliveira <ol...@milu.ipn.pt>.
Hello,
when we are writting a JSP and the JSP uses a Bean, if we do something
like:
<jsp:getProperty name="mybean" property="username" />
the JSP and the Bean itself already know that the method to be invoked
inside the bean is the "setUsername" method?
Is it allways case sensitive? I mean, if we have for instance the
property "password" we would have a correspondent method called
"setPassword"?
Best Regards
Rui Oliveira
P.S.: we can I find extended info on the JSP tag?

Hello Shridhar,
the standards have evolved. Tomcat is a Servlet 2.2 container and expects
JSP 1.1 pages.
Read the documentation from Sun
