[JSch-users] Exec

[Marcus D. <mde...@st...>]

Hi there!

I want to use jsch to start a java (rmi) server on a remote machine.
However, I just can't start the command, I don't know why.
Everything else (scp, etc) just works fine.

Thanks in advance for any help!


The command looks like:
---
nohup /home/mdeluigi/java -Djava.security.policy=smp.policy -jar  
smp.jar --server 1>smp.out 2>smp-error.out &
---
(yes, I have the vm locally)

and the code like this:
---
		JSch jsch=new JSch();
		
		Session session=jsch.getSession(user, host, 22);

		UserInfo ui=new MyUserInfo(password);
		session.setUserInfo(ui);
		session.connect();

		Channel channel=session.openChannel("exec");
		( (ChannelExec)channel ).setCommand(command);

		channel.setXForwarding(false);
		channel.setInputStream(null);

		( (ChannelExec)channel ).setErrStream(System.err);

		// execute the command
		channel.connect();
		
		// .. and finish
		channel.disconnect();
		session.disconnect();	
---

where:
---
	class MyUserInfo implements UserInfo {
		String passwd;
		
		public MyUserInfo() {
			super();
		}
		
		public MyUserInfo(String passwd) {
			this();
			this.passwd = passwd;
		}
		
		public String getPassword() { return passwd; }
		public String getPassphrase() { return null; }
	    public boolean promptPassphrase(String message) { return true; }
	    public boolean promptPassword(String message) { return true; }
	    public boolean promptYesNo(String message) { return true; }
	    public void showMessage(String message) { }
	}
---

Does anybody have an idea, what's wrong?

Greetings,
