When you create a process like this, its up to you to read and write
to the process. This means that any output from your batch file will be
lost unless you deal with is (Process has methods to get the input and
output streams for standard in/out/error).
I would suggest you try running your batch file from the tomcat's
home directory. The problem is usually one of two things. Either you have
relative paths which aren't valid in the current context or you are
expecting environment variables that aren't valid. (Or possibly its
actually working but you aren't catching the batch file's input to know
that).

OK Milt thanks.
I should read the spec before I ask. It clearly says:
"This method was originally defined to return an Enumeration of all the
servlet names known to this context. In this version, this method always
returns an empty Enumeration and remains only to preserve binary
compatibility. This method will be permanently removed in a future
version
of the Java"
Oh, yeah, should've thought to suggest just looking at the spec. I
get a lot of my info on the spec changes from a couple of articles
Jason Hunter (author of O'Reilly's Servlets book) wrote for JavaWorld.
I don't have the exact URLs handy, but one is from December 1998 (the
one that covers the changes from 2.0 to 2.1) and one is from October
1999 (from 2.1 to 2.2) -- and that should give you an idea how old
this stuff is.

Hi all.

PrintWriter out = res.getWriter();

However the Enumeration returned by context.getServletNames() is
empty!
It is supposed to return the serlvets loaded (including Loaded
itself).
I know that this method has been deprecated in jdk1.3, which I'm
using, but it should work anyway.
Any suggestions?
Why do you think it should work even if it's been deprecated? This
method was deprecated long ago, in JSDK Spec 2.1, and doesn't do
anything anymore (like it's related method, getServlet()).

What I'm trying to get at is, is apache forwarding the request to tomcat. That will help isolate where the problem is at. In particular, if it's an apache thing, it means the request isn't even getting to tomcat, so it probably has to do with the relevant Mount (ApJServMount, ApJkMount) directives in the tomcat/apache conf file (or, more accurately, the lack of such). This is a problem I ran into when I was setting up some stuff. Did you see Jeff Kilbride's recent post? Apparently he was able to get it to work by adding an appropriate ApJkMount directive.

My impression is that the url-pattern's in servlet-mapping's are meant to follow the context part of the URL, and that you don't need to include "/servlet" (although you do need to include it if you are just using the servlet-name or the fully qualified servlet-class). That is, part of the point of using servlet-mapping's is so you don't need to have the "/servlet" in the URL. This might explain some of your apparent anomalies when using "test" (you had it both as the servlet-name and the url-pattern in a servlet-mapping, IIRC). This mapping is supposed to map everything under /servlet/foo/bar/ to servlet1 -- but as you can see, Tomcat is saying /servlet/foo, with extra path info /bar/myServlet, doesn't exist. When I pull up mydomain.com/test/servlet/requestMap.Servlet1 or mydomain.com/test/servlet/servlet1, everything works as it should. So, Tomcat is not paying attention to the servlet-mapping entry.
