強迫IE用IE7的相容性檢視模式

寫個class繼承javax.servlet.Filter，在doFilter裡撰寫以下程式：

public void doFilter(ServletRequest aRequest, ServletResponse aResponse, FilterChain aChain)
        throws IOException, ServletException {
    //強迫IE用IE7的相容性檢視模式
    ((HttpServletResponse) aResponse).setHeader("X-UA-Compatible", "IE=EmulateIE7");
    aChain.doFilter(aRequest, aResponse);
}

Programmatic hot deploy with Jetty

1. Create the server:

   Server jetty = new Server();

    

2. Create a handlerCollection with a ContextHandlerCollection in it:

   HandlerCollection hc = new HandlerCollection (); ContextHandlerCollection contextHandlerCollection = new ContextHandlerCollection(); hc.setHandlers(new Handler[]{contextHandlerCollection}); jetty.setHandler(hc);

    

3. Start the server:

   server.start();

    

4. Hot deploy your web application:

   WebAppContext warWebappContext = new WebAppContext(); //configure it ... contextHandlerCollection.addHandler(warWebappContext); warWebappContext.start();

    

5. Hot undeploy your application:

   //get the WebAppContext to undeploy... WebAppContext toUndeploy = getWebAppContextToUndeploy(); //stop it toUndeploy.stop(); //and remove it from the handler collection contextHandlerCollection.removeHandler(toUndeploy);

   In a nutshell, the trick is to use a HandlerCollection for your WebAppContextHandler.
