Netbeans Run-> Stop Build不会停止正在运行的Java进程

Question

I'm using Netbeans 7.1.2 on Mac OS X Lion 10.7.3.

I have a simple java server (using netty) project and after I build and run the project then try to stop the running by Run->Stop Build it does not terminate the java server process.

For example, my server app uses port 8080 and even after I stop running from the netbeans the port 8080 is in use and the app keeps running. I have to manually kill the java process from activity monitor.

What's the correct procedure to end the running app started by Netbeans?

Greatly appreciate your help. Thanks in advanced.

Have a look at the documentation: http://netty.io/docs/stable/guide/html/ . Scroll down to section 9. Shutting Down Your Application.

Your main app ahs to look something like:

package org.jboss.netty.example.time;
public class TimeServer {
    static final ChannelGroup allChannels = new DefaultChannelGroup("time-server"(35));
    public static void main(String[] args) throws Exception {
        ...
        ChannelFactory factory = ...;
        ServerBootstrap bootstrap = ...;
        ...
        Channel channel = bootstrap.bind(...);
        allChannels.add(channel);

        ...

        // Shutdown code
        ChannelGroupFuture future = allChannels.close();
        future.awaitUninterruptibly();
        factory.releaseExternalResources();
    }
}

You handler needs:

public void channelOpen(ChannelHandlerContext ctx, ChannelStateEvent e) {
    TimeServer.allChannels.add(e.getChannel());
}

You have to: 1. Store all your channels in a ChannelGroup 2. When shutting down, close all channel and release resources.

Hope this helps.
