The mechanics of managing the session (state) in
a non-session oriented protocol (such as http) is
pretty much the same in most products.

unique session ids for multiple users?

Hi Sam,
You can use the "res.sendRedirect(URLName)" method, where "res" is the
"HttpServletResponse" kindof object. It'll be a good practice to encode the
URL first using the "res.encodeUrl(URLName)" method and then pass it to
"sendRedirect()".

All,
I'm not able to use the getRequestDispatcher.forward() method. I'm using the
JSDK 2.0 which, as far as I can tell, doesn't include this method.
The .92 JSP spec says,
com.sun.server.http.HttpServiceResponse.callPage(String uri,
HttpServletRequest request)
is now:

Right, so it is just like a "global" variable that exists for the lifetime
of the pagecompiled JSP (which is a servlet). Application is a poor choice
of words here.

Its just a matter of wording
lets assume you wrap this application object in a bean

private Object m_staticobject;
public Object getStaticObject()
{
return m_staticobject;
}
}

With the announcement that Sun is "embracing" XML, can we expect built in
support within JSP. Since it's still not release, there is enough time to
add the support.

Dan,
lifespan=application means that the object won't be created the next time you
call that JSP page. If you want to share the same (static) instance of an
object across different servlets or JSP then you can do either of 2 things:
1)wrap that object in a bean
2)<% TheStaticObject.method(); %>
I think it's better to use standard XML tags like the following
rather than special <% %> tags.

It was not clearly spelled out in the spec but thats how I have implemented my
JSP engine. You have to remember that the JSP code is compiled into a servlet.
So if you want to store the object through the life of the application (global
or member variable) then the natural way for the JSP engine
If the processRequest method of a JSP-aware bean throws an
exception (say NullPointerException), shoudn't the JSP runtime detect the
exception and redirect to an error page? I've tried this with both JRun 2.3 and
the Sun 0.92 reference implementation, and they both swallow the exception. The
I disagree with both camps to some extent.
1. Introducing new tags is not the right way to go
about it. There should be very few tags (Loops,
conditionals and properties are about all you need in
HTML). Look at how Apple WebObjects is structured:
There is but one special HTML tag: . That's

Thats one solution. T
Does anyone know how to apply this "fix" to WebSphere. Probably the two
most annoying things about JSP IMO are:
1) New beans (i.e. non servlet classes) added to WebSphere's

detected, and
2) New JSP files that are invoked vi
It is unclear to me how the application scope works. In 0.91 we've had to

how does the 0.92 "application" get created and destroyed?
