Method Details

doGet

protected void doGet(HttpServletRequest request,
 HttpServletResponse response)
              throws ServletException,
IOException

For a given lucene field name parameter, this method either forwards or redirects to the target URL. The target URL is generated by inserting the target lucene field into the target work url, if a document could be identified by the source field. Otherwise, a document is searched for using the page field; if a document is found in this alternative way, target field and page field of the document are inserted into the target page url. NOTE: If you forward, the target URL must be on the same server and must be below the context root of this servlet, e.g. this servlet can not forward to a target above '/'. A redirect changes the URL displayed in the browser, a forward does not.

Overrides:

doGet in class HttpServlet

Throws:

ServletException

IOException
