RE: Implicit objects in JSP pages

[Brook Monroe]

After looking at the generated Java file, I find that the request object is
available because it's a parameter to _jspService().  I was attempting to
instantiate my objects via calls to request.getAttribute() at the point of
declaration, not in the first real code block in the page.  Once I moved the
instancing to the first code block, everything was fine.  (Some aspects of
JSP development are counter-intuitive to me, I'm afraid.)

Thanks for checking up on my query!

I believe that's correct how are you using the 'request' reference?

Implicit objects in JSP pages

[Brook Monroe]

According to what I've read, there should be a
javax.servlet.http.HttpServletRequest instance by the name of "request"
available to me in my JSP at compile time without my having to do something
special to obtain it, yet Jasper is insisting that no such object is
available.  Have I skipped a step somewhere?

jbm!

Cool...I'll check that ASAP.  (Had to focus on different project for the
afternoon...)

If "MySeatMap" is your Context root, then you do not need to include that.
String  target  = "/seatmap.jsp";
rd = getServletContext().getRequestDispatcher(target);

should suffice.

Subject:  JSP path relative to servlet?

Now that I've got my servlet's XML parsing largely debugged, it's time to
see some output.

The problem is this (mucho code removed):

   String  target  = "/MySeatMap/seatmap.jsp";
   .
   .
   .
   rd = getServletContext().getRequestDispatcher(target);
   rd.forward(request,response);

I get 404'd, with the error that the JSP file can't be located.  What am I
doing wrong?  (rd is declared, I just left that out.)

jbm!

RE: Getting a servlet running under Tomcat-Apache 4.0.3

[Brook Monroe]

Jeff:

The path listed in the manager is /MySeatMap.

http://localhost:8080/MySeatMap/seating works.  Amazing. :)  Got a big list
of errors to resolve, which is what I was looking for.  Thanks!

(Off for the rest of the day...see y'all in the AM)

jbm!

What path does the Manager display for your app? 

If tomcat is auto-deploying your app, then it should be /MySeatMap since
that is the subdir of webapps in which your WEB-INF/web.xml resides.
Then you should be accessing http://localhost:8080/MySeatMap/seating

If you are using a  element in
server.xml, 
then your URL should be http://localhost:8080/mypath/seating

Remember, the  elements only tell the container
which servlet classes to invoke WITHIN that servlet's context path.
Nothing in web.xml defines the context path itself. 

Try the above URL's and let us know if it works.

>>  >   debug="0" reloadable="true"/>

That was the first thing I did, actually.  No variations on that theme seem
to be making any difference, and it doesn't matter whether it's under the
Tomcat-Standalone or Tomcat-Apache section

Jeff:

>>Under what context path is your servlet deployed? The

It's deployed where the examples are, and where the manager is.

The specific path is

:\Tomcat\webapps\MySeatMap\

with the class files in :\Tomcat\webapps\MySeatMap\WEB-INF\classes

I've tried permuting this almost to exhaustion.  I've been reading the
example setups, and I can't even figure out how the HelloWorldExample class
gets called.  Something to do with  tags, but I can't make out
what's happening.

And to repeat: I know the servlet is running, because the manager and the
logs confirm it.

For grins and giggles, here's the web.xml file.


http://java.sun.com/dtd/web-app_2_3.dtd";>




MySeatMap


/MySeatMap




MySeatMap


/seating




MySeatMap


/seating/




MySeatMap

*.map



And the context entry:



Anyone see anything (in)obviously wrong?

jbm!

Getting a servlet running under Tomcat-Apache 4.0.3

[Brook Monroe]

Greetings, y'all.
* I've read all the documentation I can find.
* I've emulated all the examples.
* I've asked people I know who have set up servlets before.

I still can't get access to the servlet I just wrote and installed.

No matter how I've set up servlet-mappings, or url-patterns, or otherwise, I
get 404'd on any attempt to test the servlet. The class files are where
they're supposed to be, and the manager HTML applet says that the servlet is
loaded and running. Supposedly (based on reading docs and looking at
examples)


MySeatingServlet
Seating


MySeatingServlet
/seating


in my web.xml file should be sufficient to get the servlet mapped to a url,
but



produces nothing but a 404, specifically

type Status report
message /seating
description The requested resource (/seating) is not available.

Obviously I'm either misinterpreting the documentation, missed something
somewhere, or making a bad assumption. I'd appreciate any input I could get
on this, because the servlet customer is breathing down my neck for the
prototype, which I would like to test before delivering it

jbm!
