JschでJavaコマンドを発行する際に問題が発生しました

Question

jschからJava commendを実行する際に問題が発生しました。私はパテを経由してSSHセッションでそれを実行する場合は、このjavaコマンドが正常に動作しますが、私のコード内で実行すると、127

の終了ステータスを返した場合、コマンドはこれです：sendCommand関数された状態で

sshCommManager.sendCommand("cmd /c java -Xms256M -Xmx1024M -jar FileCatalystTester.jar -basic /Y"); 

execの派生物の例。ここで私が書いた全体SSHCommManagerされています。そのjavaコマンドが動作しませんなぜ私は理解できないよう

public class SSHCommManager extends Observable{ 

    private JSch jsch; //ssh library 
    private static String user = "what"; 
    private static String password = "youwhat"; 
    //private static String host = "192.168.1.1"; 
    private static SSHCommManager sshCommManager; 
    private Session session; 
    private Channel channel; 
    public boolean commsConnected = false; 
    private int aPort = 22; 

    private SSHCommManager() { 

     this.addObserver(MainUI.getInstance()); 
    } 

    public static SSHCommManager getInstance() { 
     if (sshCommManager == null) { 
      sshCommManager = new SSHCommManager(); 
     } 
     return sshCommManager; 
    } 

    public void init(String aHost) { 

     try { 
      jsch = new JSch(); 

      //System.out.println("Getting ssh session..."); 
      session = jsch.getSession(user, aHost, aPort); 
      session.setX11Host(aHost); 
      session.setX11Port(aPort + 6000); 

      //System.out.println("Getting user info..."); 
      session.setPassword(password); 

      java.util.Properties config = new java.util.Properties(); 
      config.put("StrictHostKeyChecking", "no"); 
      session.setConfig(config); 

      System.out.println("Connecting to ssh..."); 
      session.connect(30000); 

      if (session.isConnected()) { 
       commsConnected = true; 
      } else { 
       commsConnected = false; 
      } 

      System.out.println(commsConnected); 

     } catch (Exception e) { 
      System.out.println(e); 
     } 

    } 


    public void sendCommandTest(String aCommand) { 
     try { 
      Channel channel1=session.openChannel("shell");//only shell 
      System.out.println("Sending Test command: "+ aCommand); 
      channel1.setOutputStream(System.out); 
      PrintStream shellStream = new PrintStream(channel1.getOutputStream()); // printStream for convenience 
      channel1.connect(); 
      shellStream.println(aCommand); 
     } catch (Exception e) { 
      System.out.println(e); 
     } 

     if (channel.isClosed()) { 
      System.out.println("exit-status: " 
      + channel.getExitStatus()); 
     } 
    } 

    public String sendCommand(String aCommand){ 

     InputStream in = null; 
     OutputStream out = null; 
     StringBuilder commandOut = new StringBuilder(); 

     try { 

      channel = session.openChannel("exec"); 
      System.out.println("Sending command: " + aCommand); 
      ((ChannelExec) channel).setCommand(aCommand); 
      //channel.setInputStream(System.in); 
      channel.setInputStream(null); 
      //channel.setOutputStream(System.out); 
      ((ChannelExec) channel).setErrStream(System.err); 

      in = channel.getInputStream(); 
      //out = channel.getOutputStream(); 

      channel.connect(); 

      byte[] tmp = new byte[1024]; 
      while (true) { 
       while (in.available() > 0) { 
        int i = in.read(tmp, 0, 1024); 
        if (i < 0)break; 
        //System.out.print(new String(tmp, 0, i)); 
        //System.out.println(channel.getInputStream().toString()); 
        commandOut.append(new String(tmp, 0, i)); 

        //setChanged(); 
        //notifyObservers(System.err.toString() + "\n"); 
       } 
       if (channel.isClosed()) { 
        System.out.println("exit-status: " 
        + channel.getExitStatus()); 
        break; 
       } 
       try { 
        Thread.sleep(1000); 
       } catch (Exception ee) { 
        throw new JSchException("Cannot execute remote command: " + aCommand + " : " + ee.getMessage()); 
       } 
      } 

      //channel.disconnect(); 
      //session.disconnect(); 

     } catch (Exception e) { 
      System.out.println(e); 
     } 

     return commandOut.toString(); 

    } 

    public void cleanupSSH() { 

     channel.disconnect(); 
     session.disconnect(); 
    } 

    public boolean isCommsConnected() { 
     return commsConnected; 
    } 
} 

は...任意の考えやヘルプをいただければ幸いです。私は実行しようとしているjavaと.jarファイルの両方に直接パスを入れることを含め、すべてを試しました。

リモートSSHサーバにアクセスするには、次のプログラムの作業

private String userName = "xxxx"; 
private String password ="xxxx"; 
private String hostName = "xxx.xxx.xxx.com"; 
private int port = 22; 
private String sdstestCommand = "java -Xms256M -Xmx1024M -jar MyProgram"; 

public void testconnect() throws JSchException, IOException { 

    JSch jsch = new JSch(); 
    Session session = jsch.getSession(userName, hostName, port); 
    session.setConfig("StrictHostKeyChecking", "no"); 
    session.setPassword(password); 
    session.connect();  
    ChannelExec channel = (ChannelExec) session.openChannel("exec"); 
    channel.setCommand(sdstestCommand); 
    channel.setInputStream(null); 
    ((ChannelExec) channel).setErrStream(System.err); 
    InputStream in = channel.getInputStream(); 
    channel.connect(); 
    System.out.println("Unix system connected..."); 
    byte[] tmp = new byte[1024]; 
    while (true){ 
     while (in.available() > 0) { 
      int i = in.read(tmp, 0, 1024); 
      if (i < 0) { 
       break; 
      } 
      String line = new String(tmp, 0, i); 
      System.out.println("Unix system console output: " +line); 
     } 
     if (channel.isClosed()){ 
      break; 
     } 
     try { 
      Thread.sleep(1000); 
     } catch (Exception ee){ 
      //ignore 
     } 
    } 
    channel.disconnect(); 
    session.disconnect();  
}  
}
