Java command line "shell" with auto-complete

Question

I need to create a Java command line to that will be invoked remotely on a server. It will need to:

• Read "lines" of text from the user.
• Recognise if the user presses the "tab" key to facilitate auto-complete.
• Recognise if the user presses the "up/down" keys for history.

Before I go off and roll my own, Is anyone aware of a Java library that might facilitate all or part of this?

i.e. From the command line in ssh it might look like this:

bob> java -jar MyTool.jar

MyTool Started.
Please enter command:

> server1 startup
server starting...
server started

> server2 load accounts
Done

> server3 shutdown
Complete

>quit
