}
public void start() throws Exception {
hash = new HashMap<String, Continuation>();
server = new Server(80);
root = new WebAppContext(server,"C:/Users/sl300/Desktop/jetty/webapps/MyFirstServlet.war","/");
server.start();
server.join();
}
public void addContinuation(String str,Continuation cc){
hash.put(str, cc);
}
}
what is wrong? or how else i can open jsp?
Would be helpful to see your web.xml file. Seems to be a problem with the servlet mapping. Another way would be to use a ServletHandler and add it to the server instance like
GrettingServlet greetingServlet = new GrettingServlet();
ServletHandler servletHandler = new ServletHandler();
servletHandler.addServletWithMapping(greetingServlet, "/your/servlet/path");
server.addHandler(servletHandler);
加载中,请稍侯......
