Re: RE: web.xml servlet and resources
One way to deal with this issue is to break down the file type in the someservlet directory rathen than having a URL mapping for the whole directory. Say for all JSP files, you have servlet-mapping servlet-nameTheServlet/servlet-name url-pattern/*.jsp/url-pattern /servlet-mapping Hope this helps. 30/01/2003 10:40:33 AM, Richard Wallace [EMAIL PROTECTED] wrote: On Thu, 2003-01-30 at 05:43, Daniel Brown wrote: Richard, You could use HttpServletRequest.getPathInfo() to read the extra path information after servlet name, read the corresponding object from disk, set an appropriate MIME type, and then send the object back in the response.

Re: web.xml servlet and resources
Richard, Usually the servlet are in the WEB_INF directory, and this is forbidden for the users. If you put an image inside web-inf/servlet/images.. you will not be able to retry it. You cannot use the url .../web-inf/images/... Usually you create a image folder at the same level that WEB_INF folder, and you put your image like img src=images/mygif.gif... Remember that the images are retry by new request to the server by the navigator (http://mihost/images/mygif.gif) for each img html token.

Re: web.xml servlet and resources
Hi Richard, if i didn't understand wrong If you want put a image using relative path, the source of your image must be src=/yourApp/images/logo.gif, for example.
