RE: can a non struts application be called from inside stuts appl
ication.
In Struts Action, the Servlet URL is prepared like this:
String requestUrl = request.getRequestURL().toString();
String webAppUrl = requestUrl.substring(0, requestUrl.lastIndexOf("/") );
String servlet1Url = webAppUrl + "/servlet1";
This URL is passed to the method getUrlResponse(String url) that I sent
earlier.
