Restricting access to code

Hi All,
I am facing a problem, regarding code security on a server.
We have configured a server which contains our code (ear present in jboss/server/xyz/deploy) in it, and need to bind the code to the server itself so that no one can take the code out of the. the problem is that the password of root for some reasons has to be shared with the users of the server, and we don't want them to create a copy of our code.
Are there some ways to achieve this ???

I have a crazy idea though, yet I'm not even sure whether it makes sense or not as I have not tried it before. In theory, because class loading in Java is based on ClassLoader conceptually speaking you can create a custom classloader that does not load the bytecode from physical files (say, instead load the bytecode over the network on initialization). As the classes have been loaded they will reside in the permanent generation of the JVM (in memory anyway, simply speaking) and there ought to be no physical files on the deployment server. So, no one can find the files in the filesystem. This is not difficult, but how to integrate that custom classloader into JBoss may be more tricky and is likely not as simple as changing some mbean descriptors. Therefore, if you have an earnest need you may need to investigate the class loading of JBoss and think along this direction.
Do share with us (I'm particularly interested in hearing this) if you can actually make it work.

We want to secure access to a server by restricting the number of users who can login to it. Our users are NIS users. Only few of them can telnet/ssh this server.
Do you have any idea on how to implement that?
