Hey Veronica, I can give you a small suggestion...you can get the user request URL, from HttpRequest instance itself. So, in your custom tag, create a HttpServletRequest instance (pageContext.getRequest()) and get the request URI using <instance>.getRequestURI()/<instance>.getRequestURL(). Store that into a Hashmap & pass it to the XSL trnasformer as a transform param. use the Hashmap key, as <xsl:param> in your XSL file. and use the param anywhere accross the XSL.
