ServiceMix4: much more than a JBI container

David Greco has posted a nice blog entry about ServiceMix Kernel. I do totally agree: ServiceMix 4 is not only a JBI container, and more precisely the ServiceMix Kernel which can be run standalone is a universal container (which does not include JBI by default) where you can deploy virtually any kind of artifact from web applications, to JBI applications or plain JAX-WS services.

SSH Server in Java

ServiceMix Kernel is a small container based on OSGi. The latest release allows external clients to connect to it and issue commands using a simple protocol implemented on top of TCP or SSL. However, this remoting protocol has some drawbacks as the internals makes it unable to do another remote login from a remote session. In addition to that, completion and history do not really work great. So I've been thinking about using the SSH protocol, which is widely used, secured, with tons of different clients available.

The project is available at and although there are lots of limitations right now, the basics of the SSH protocol work. I plan t
