別の問題で再び戻ってきました。質問/回答を検索しようとしましたが、これまでのところどれもうまくいかなかったため、別の問題を投稿することにしました。Java/Tomcat で小さな REST JAXRS WebService を実行しており、JSP ページからコマンドを送信してソケット クライアントを開始および停止したいと考えています。これまでのところ、ソケットの開始を達成しましたが、停止できません。何が間違っていますか?

編集 1: 同じソケット関数 (同じクラスの PLC を使用) を JFrame インターフェイスでテストしました。1 つのボタンは REST 関数を表し、1 つの接続と他の切断は 2 つのボタンを備えています。

マイレスト機能

NewTen_PLC m_plc = new NewTen_PLC(0x01, "Central Park", "10.80.4.10", 5001);
Thread m_thread;

@PUT
@Path("/connect")
public void Connect(InputStream is)
{       
    System.out.println("CONNECT COMMAND RECEIVED");
    try
    {
        System.out.println( "Starting Executor" );

        //Using thread manager
        //ExecutorService threadExecutor = Executors.newCachedThreadPool();
        //Start Thread
        //threadExecutor.execute(m_plc);            
        //Shutdown working threads when task is complete
        //threadExecutor.shutdown();

        //Using Thread
        m_thread = new Thread(m_plc);
        m_thread.start();

        System.out.println( "Tasks started, main ends.\n" );
    }
    catch(Exception ex)
    {

    }       
}

@PUT
@Path("/disconnect")
public void Disconnect(InputStream is)
{
    System.out.println("DISCONNECT COMMAND RECEIVED");

    try
    {           
        //m_plc.closeConnection();          
                    m_plc.m_bConnected = false;
    }
    catch(Exception ex)
    {
        System.out.println("Error while trying to close socket");
        ex.printStackTrace();
    }       
}

これは、Socket 関数とスレッド Run メソッドを含む Class PLC です。

それを止める方法はありますか?
