Help Needed

["Ramesh Kumar . T" <ra...@india.adventnet.com>]

Hi ,

I had previously seen some
xml tags in earlier versions of tomcat (I do not remember the version)
something like
<jsp:scriptlet>
</jsp:scriptlet>
(but this does not work right now )

instead of the
<%
%>
tags

                  Is the Xml  format going to be a standard or some
thing?????
can somebody  exaplain this

I would appreciate any links to Model2 architecture  described by sun
and links for writing tag libraries

One more thing I just tried Tomcat4.0 beta .
What is this catalina???
I Could not find any documents describing  the architecture of tomcat .
Can anyone give me some pointers???

Thanks
Ramesh

The <jsp:scriptlet> and other similar tags are used in the "XML view" of a JSP
page.  This syntax was optional in JSP 1.1 (and is not supported by Tomcat 3.x),
but is required by JSP 1.2 (and is supported by Tomcat 4.0).  Some syntax
details have changed between 1.1 and 1.2 -- you will want to download the JSP
1.2 spec from:

    http://java.sun.com/products/jsp/download.html

to see all the gory details.

One place to start on architectures is the Struts project at

    http://jakarta.apache.org/struts

There are also many useful links about tag libraries (including a tutorial) at:

    http://java.sun.com/products/jsp

For Tomcat 4.0, the source distribution has a few documents and diagrams in the
"catalina/docs/dev" directory.
