Peter, All this info is available from the current HttpServletRequest, accessible within your tag handler by 'pageContext.getRequest()'.
HttpServletRequest request = (HttpServletRequest)pageContext.getRequest(); request.getServerName() ( == hostname) request.getProtocol() ( == http/majorVersion.minorVersion) request.getServerPort() ( == 80) request.getContextPath() ( == /webapp/servlet) Cheers, Borislav -----Original Message----- From: A mailing list about Java Server Pages specification and reference [mailto:[EMAIL PROTECTED]] On Behalf Of Peter Dolukhanov Sent: Sunday, October 13, 2002 7:56 PM To: [EMAIL PROTECTED] Subject: Tag Lib/Servlet Question Dear All, I have successfully built a servlet that generates a GIF/JPEG file depending on parameters that are passed to it. I am trying to expand the functionality of it by creating a Custom Tag, that on execution with certain parameters will return a <img> tag pointing at that specific servlet with the correct parameters etc.. i.e. <customTag:tag1 text="abcd" width="40" position="top"> will return <img src="http://hostname/webapp/servlet/package.servlet?text=abcd <http://hostname/webapp/servlet/package.servlet?text=abcd&pos=top> &pos=top" width="40"> As my tag library and servlet are in the same package, I know that my servlet is located at http://hostname/webapp/servlet/package.to.servlet?parameter1=value... Is there any way for me retrieve the http://hostname/webapp portion of the URL from the tag at runtime, as obviously I don't know from what directory the taglib JSP is being executed from. I have tried servletContext.getRealPath(.) but that returns me a path on the hard disk to my web app. Any ideas how I can circumvent this problem?
