expose ssh commands as web service through ssh proxy using java

I need a SSH proxy which will be exposed via HTTP interface. The proxy needs to be developed in JAVA. In the end I need to be able to call ,through the proxy, some specific shell commands on the client (that runs the SSH agent) using web services.

I found SSH Web Proxy which seems to be very close to what I want. Is there any other commercial or open source framework/library/API that can match my needs?
