I'm having a wonderful time this morning reading the HTTP 1.1
spec. YUCH! I hate reading IETF and W3C spec documents! Can
anyone recommend a good book, tutorial, or even a class that discusses "using"
HTTP versus "implementing" HTTP? I don't know about anyone else, but to me
it's like pu
I think that you can still do this with one servlet. In earlier posts
(subject - Which Architecture), Craig discussed a servlet design that used
an action parameter in the servlet request to determine how to handle the
request. It seems to me that you have at least one additional dimension,
i.e.
I believe that this is a known problem in JRun 2.3.3. If you have a long
block of non-JSP code, then you will get this error. You can fix it by
applying the 2.3.5 patch or inserting JSP comments in the long blocks of the
non-JSP code.

One suggestion: Have you tried encoding the value of article before passing
it in the request parameter? It may be that the "/" character is causing a
problem. You can use the JavaScript escape() method to encode it.
Also, this is a dynamic include so you have to use jsp:include.

I do the same plus this:
Date dateInPast = new Date(0);
response.setDateHeader("ExpiresAbsolute", dateInPast.getTime());
and I wrote it as a scriptlet in a separate file that is included in my JSP
pages using <%@ include file %> so that I would have to insert a call to a
method.

You cannot do this because JSP scriptlets are server side entities.
They are accessible from a client. The nearest alternative approach that I
can think of is to use a scriptlet to generate JavaScript code for the onClick
handler and use meta tags in the header to refresh the page. While
First, with an HTML link, you're not forwarding a request. Instead, the
client is creating a new request when the user clicks on the link, and this
request is not the same as the request object that is used on the
server-side. The servlet container creates a HttpServletRequest object from

I think so. There are basically two ways of doing this (that I can think
of).

That includes searching inside jar files and zip files. Then, if you
understand Java bytecode, you can decode the package name of for each cla
The address of the page that contains the top-most frameset will always

The following javascript can be used once on the target page to do the same
thing. The other has to be used everywhere that you reference the target

I haven't tried this yet, but was considering this approach:

session object
- redirect the client to the first JSP page of my application

The short answer is yes you can. Why it's not working for you is most
likely a problem in your environment or one of the individual JSP pages.
Here are some tests to narrow down the problem: Can you load the frameset
jsp page without referencing menu.jsp? Can you load menu.jsp without using

Javasoft provides a JDK plugin for JDK 1.1 and JDK 1.2. Just search for
"java plugin" on the Javasoft site. They also provide a tool that will

I don't know why you want to do this, but theoretically you can do it by:
- getting the current thread object with Thread.currentThread()
- use a hashtable to store (Thread object, count object) pairs. Note that
count is now an Integer object and not an int.
- use the hashtable to lookup a cou

If you're wanting a JSP error page to be shown, why not just throw the

You're right that the session values are stored in the server, and I think a
