Your replies arrive at strange places...

What Lipska posted is right on the money. In JSCH it is called port 
forwarding because they do not know what they would be forwarding but 
since in your case you would effectively be forwarding HTTP through the 
SSH connection it becomes tunnelling.

If you can access the servlet directly at 
http://moonprod:28080/servlets/myservlet (like you said in your other 
post that was also misplaced) then you would not need the SSH 
connection. However, if the servlet is not publicly accessible creating 
the tunnel is the only option.

Thank you Lipska for clarifying my post. This stuff is everyday routine 
for me so I may have rushed through the explanation.

Think about it, what do you want to do.

You want to access a port that is not available to the outside world, 
that's you, you are the outside world.

There is a way, and it's by making a tunnel through the obstruction[s].

So you set up your tunnel by calling Jsch#connect,

once you have a connection you effectively have a tunnel from you to the 
server, now you say,

session.setPortForwardingL(8888, moonprod, <remote port>);

This says, anything I send to port 8888 on my local machine I want to 
forward to port <remote port> on the remote machine.

Now, if there is a servlet container on port remote:whatever and you 
POST to localhost:8080 the request will be forwarded *through the 
tunnel* to remote:whatever where your servlet is waiting. Bingo, you 
just hit your servlet by tunneling through the obstructions via the 
secure connection you set up via Jsch.

Give it a go and report back and let us know how you got on.

The client is a University, and they are not too responsive or cooperative, more just "We don't know what you are talking about make it work we won't help you."

So after two days of waiting for them to open it to me, I decided there must be an alternative way. 

Now, they have decided to migrate the server, so U have no way of testing it until they let me know the new one is up. So as soon as I can, I will test the port forwarding using Jsch here. I already know the servlet and clent work flawlessly (they use basic authentication and encrypt the post parameters -- there would be very little problem even if they exposed it to the outside world) as I have run them communicating together on my local -- so if there is a problem when I run it then it is because i have the tunnel set up incorrectly.

Thank you guys for your elp -- I will report back here hopedfully within the next 24 hours. RVic

Good for you, never let the buggers get you down.

Gentlemen,

It works, I'm able to hit the server now (though my servlet returns a 500 error, and I need to look in the tomcat logs to figure out why that might be) at least I am able to connect. Thanks for all your help on this. RVic.

Good for you. And glad to hear we could be of service.

Cheers.

"I know! You construct a weapon. Look around, can you form some sort of 
rudimentary lathe?"

Surely one of the best *bad* spoof movies ever made.
