One way to deal with this is to have all your servlets and JSP pages at the same
"directory level", so that relative references work correctly. To do this, you
would map your servlets to a name component with one level, like this:
<servlet>
<servlet-name>myservlet</servlet-name>
<servlet-class>com.mycompany.mypackage.MyServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>myservlet</servlet-name>
<url-pattern>/myservlet</url-pattern>
</servlet-mapping>
Now, you can have a reference in your JSP page "/index.jsp" (relative to the
context path -- see below for more info) to a servlet path like "myservlet", and
your servlet can render links that are relative to the document root as well.
Alternatively, if you need multiple directory levels, you can include the following
tag in the <head> section of your generated page:
<base href="/qaTool/index.jsp">
to have the relative links resolved correctly. In the Struts Framework
<http://jakarta.apache.org/struts> there is a custom tag that does this for you
automatically, so all you have to say is:
<form:base/>
and it renders the appropriate base tag based on the address of the page itself.

If "/qaTool" is the context path for your web application, change the first line
above to say:
String URL = "/index.jsp";
because the path you specify for a request dispatcher must be relative to the
context path. The nice thing about this is that you can install your webapp on a
different context path and it will still work.
