JBossMQ offers many transport mechanisms all of which can be configured to run in plain text mode or over ssl.

• UIL2ConnectionFactory - this is the prefered connection factory (uses a single tcp/ip connection from client to server).

• OILConnectionFactory  - uses two tcp/ip connection factories, one from client to server, the other from server to client.

• OIL2ConnectionFactory  - an unsuccesful experiment at rewriting OILConnectionFactory

• RMIConnectionFactory - uses two RMI connections, client->server and server->client

• HTTPConnectionFactory - a servlet that allows transport over http - uses polling to deliver messages

• JVMConnectionFactory - an in memory connection factory that uses method invocations, not useable outside the JVM
