pathInfo in a custom tag
Hi all, I'm trying to get the request path for a page from inside a custom tag. The tag itself extends TagSupport. I'm getting the ServletRequest object from the pageContext.getRequest() - this object is an instanceof HttpServletObject, but when I ask it for pathInfo() I get null... HttpServletRequest request = (HttpServletRequest) pageContext.getRequest(); String path = request.getPathInfo(); // aways null? Is there a way to do this inside the tag, or will I have to pass the path in from the JSP? Cheers Chris
Re: pathInfo in a custom tag
Chris, I just wanted to make sure you're checking for the right thing in your code, and if you are I apologize. For the following example URL: http://www.foo.com/FooServlet/testme?hey=you Assume that FooServlet and FooServlet* are both mapped to FooServlet. Here are the results of the following calls: HttpServletRequest request = (HttpServletRequest)pageContext.getRequest(); String servletPath = request.getServletPath(); // here servletPath = /FooServlet, same as cgi.SCRIPT_NAME String pathInfo = request.getPathInfo(); // here pathInfo = /testme, same as cgi.PATH_INFO String queryString = request.getQueryString(); // here queryString = hey=you, same as cgi.QUERY_STRING If you want some very helpful documentation on CGI variables and their definitions, check out this URL: http://cgi-spec.golux.com/draft-coar-cgi-v11-03.html Jeff Hubbach.

Re: pathInfo in a custom tag
Haha, got it... The url I had was http://localhost/myApp/logon.jsp, so getPathInfo() is null, but getServletPath() was logon.jsp Kinda obvious really :) Cheers Chris Jeff Hubbach wrote: Chris, I just wanted to make sure you're checking for the right thing in your code, and if you are I apologize.
