如题，我现在window的程序上，需要通过访问linux服务器，执行一条Java命令，正常的linux命令没问题了，但是java命令返回结果正常但服务器那边没有结果，代码如下：





public static void main(String[]  args){

		int returncode =-10;

		FtpToSever fts = new FtpToSever();

		fts.setIp("172.23.19.127");

		fts.setUser("root");

		fts.setPassword("`123qwer");

		fts.connect();

		//fts.upload(sendFiles);

		//returncode = fts.execute("ls");

		returncode = fts.execute("java -jar /home/eam/TestCommand.jar \n");

		System.out.println(">>>>>>>>>>>>>>>"+returncode);

		fts.loginOut();

	}	/**

	 * 执行shell命令

	 * */

	  public int execute(String command) {  

	        int returnCode = 0;  

	        try {  

	            // Create and connect session.  



	            // Create and connect channel.  

	            excechannel = (ChannelExec)sshSession.openChannel("exec");  

	            excechannel.setCommand(command);  

	   

//	            excechannel.setInputStream(null);  

	            BufferedReader input = new BufferedReader(new InputStreamReader(excechannel  

	                    .getInputStream()));  

	   

	            excechannel.connect();  

	            System.out.println("The remote command is: " + command);  

	   

	            // Get the output of remote command.  

	            String line;  

	            while ((line = input.readLine()) != null) {  

	                stdout.add(line);  

	            }  

	            input.close();  

	   

	            // Get the return code only after the channel is closed.  

	            if (excechannel.isClosed()) {  

	                returnCode = excechannel.getExitStatus();  

	            }  

	   

	        } catch (JSchException e) {  

	            // TODO Auto-generated catch block  

	            e.printStackTrace();  

	        } catch (Exception e) {  

	            e.printStackTrace();  

	        }  

	        return returnCode;  

	    }
