Yes, and there are multiple options:

• use an UrlRewriteFilter to rewrite the given url to questions?id=2585407, then read the request parameter
• use some framework like Spring-MVC that supports beatiful URLs
• map the servlet to /questions/* (in web.xml) and then parse the getRequestURI() (by stripping the prefix and the request.getContextPath())

use following pattern in URL mapping

/questions/*

If your <url-mapping> is set to

/questions/*

Then you would get your question id by using request.getPathInfo() (request being HttpServletRequest).
