Recommended usage
The recommended way of using the EngineClient Bean is as follows
1. Call the default constructor of the bean (the one with no parameters)
2. Call setHost() to set the host on which the remote correlator is running
3. Call setPort() to set the port on which to contact the remote correlator
4. Call connectNow() or any other method which creates a connection to the remote correlator. All the specialized operations listed in the following sections will create a connection if one does not already exist when they are called.
