Reading the CGI Variables in JSP:

String AUTH_TYPE	 = request.getAuthType();
Int CONTENT_LENGTH	 = String.valueOf(request.getContentLength());
String CONTENT_TYPE	 = request.getContentType();
String DOCUMENT_ROOT	 = getServletContext().getRealPath("/");
String PATH_INFO	 = request.getPathInfo();
String PATH_TRANSLATED	 = request.getPathTranslated();
String QUERY_STRING	 = request.getQueryString();
String REMOTE_ADDR	 = request.getRemoteAddr();
String REMOTE_HOST	 = request.getRemoteHost();
String REMOTE_USER	 = request.getRemoteUser();
String REQUEST_METHOD	 = request.getMethod();
String SCRIPT_NAME	 = request.getServletPath();
String SERVER_NAME	 = request.getServerName();
Int SERVER_PORT	 = String.valueOf(request.getServerPort());
String SERVER_PROTOCOL	 = request.getProtocol();
String SERVER_SOFTWARE	 = getServletContext().getServerInfo();

Using the above in a JSP page:

<%=request.getServletPath()%>

Ot the XML equivalent of:

<jsp:expression>
request.getServletPath()
</jsp:expression>
