There must be something very strange with your code if a css file is
being interpretted as a class or resource on the classpath. How are you
calling it? It should be in a standard link tag in the head of your jsp
page as in <link type="text/css" src="<%= request.getContextPath()
%>/stylesheets/catalogue.css"> or <link type="text/css"
src="${pageContext.request.contextPath}/stylesheets/catalogue.css"/>

I'm beginning to see my problem is a bit more complex than I had
mentioned.
Here is the situtation: I have two JSP's, login.jsp and
catalogue.jsp. Login JSP calls a servlet to do some processing. If it
is successful, the servlet forwards the request and response objects
to "/catalogue.jsp".
Whenever I access "catalogue.jsp" by entering in its absolute URL,
everything works fine. I can still have my relative img links to the
images contained in the same folder, e.g., <img src="image.jpg">
However, if "catalogue.jsp" is accessed by the servlet forwarding the
request and response objects to "catalogue.jsp" then none of the usual
relative URL's work. In fact, the servlet will not even compile
correctly:

This is only remedied if I use relative links to the images beginning
with ".." For example, if the image links are constructed like <img
src="../image.jpg">. Then the forwarding, runtime compilation of the
servlet, and the image URL's in the document work fine.
To illustrate how this works, say I have 3 images, one of them with a
"correct" relative URL location, and the other two using "../" before
the image filename. If I access the JSP using an absolute URL, one of
the images will work, if I use dispatcher forwarding, 2 of them will
work.
I am using Eclipse for development.

What does the URL in your browser look like when you are access the
JSP pages? The browser constructs the full path to the image from
the URL used to request the page (JSP or HTML -- the browser doesn't
know the difference).

Nope. They are "rooted" right where they are although internal
forwarding can make the request URL different from the actual
location of the JSP. In the past, I've done stuff like <img
src="${pageContext.request.contextPath}/WebContent/image.jpg"> to get
around these issues with an absolute path to the image. My example
assumes a servlet spec 2.4 webapp and container.

This thread is related to relative URL within JSP's and how they
refer to the local directory structure in a web application.
My directory structure in Tomcat goes something like this:
webapps/inprogress/WebContent
(Accessed through Tomcat as such:
http://127.0.0.1:8080/inprogres/WebContent
where WebContent contains my JSP and HTML files, WEB-INF, etc.
When creating img links to image files in the WebContent folder, I
noticed
1) HTML files can use the correct local pathname, e.g., <img
src="imagname.jpg">
however,
2) JSP files, even though accessing image files in the same
directory must use the previous directory, e.g., <img
src="../imagename.jpg"> even though the images are contained in the
same directory.
My assumption is that JSP files are "rooted" in the WEB-INF
directory and so must use the previous directory notation back up a
directory to access the images contained the WebContent folder where
everything else is.
Thus, I have two questions:
1) Why does this occur, and how can I modify my xml configuration
files so that JSP's reference links exactly as an html file in the
same directory would?
2) How can I change the root folder of tomcat to the
webapps/inprogress/WebContent directory, which xml files, and how
exactly should I modify them?
Thanks,
Mike M.
