Accessing a jsp directly behaves differently than accessing through a servlet-mapping.

           Summary: Accessing a jsp directly behaves differently than
                    accessing through a servlet-mapping.
           Product: Tomcat 4
           Version: 4.0.1 Final
          Platform: PC
        OS/Version: Windows NT/2K
            Status: NEW
          Severity: Critical
          Priority: Other
         Component: Catalina
        AssignedTo: tomcat-dev@jakarta.apache.org
        ReportedBy: joseph.swiderski@ca.com


System - Windows NT Version 4.0 (Build 1381: Service Pack 6)

Apache Tomcat Version - 4.0.1 Final

Impact - Bug has a severe impact on our production software release. The 
inability to make the Reference Implementation work may have cascading effects 
on our product's usability with other containers (WebSphere, WebLogic, etc.).

Bug Summary:
When accessing the jsp directly, all is well.

>From the web.xml:
<servlet>
    <servlet-name>gui</servlet-name>
    <jsp-file>/tsgui001/gui.jsp</jsp-file>
</servlet>
<servlet-mapping>
    <servlet-name>gui</servlet-name>
    <url-pattern>/gui</url-pattern>
</servlet-mapping>

When accessing the jsp via a servlet-mapping, a relative look up fails. Notice 
the 404 for CoolGen_Make.js.

1. JSP /tsgui001/tsgui001/gui.jsp is requested via /tsgui001/gui.
2. gui.jsp forwards to a Servlet.
   <jsp:forward page="/servlet/tsgui001.GUI.ServletManager" />
3. The ServletManager streams the html page (no physical file on the file 
system).
4. The html page has an absolute reference to main_menu.js file:
   <HEAD>
    <SCRIPT LANGUAGE='JavaScript1.2' SRC='/tsgui001/tsgui001/main_menu.js' 
TYPE='text/javascript'></SCRIPT>
   </HEAD>
5. main_menu.js has an relative reference CoolGen_Make.js:
   document.write("<SCRIPT LANGUAGE=JavaScript SRC='../CoolGen_Make.js'>");

The differing behavior between the two access styles is unexpected and the 
specification does not list this as an expected behavior.
