* Create and open a Connection.
* <p>
* There are 2 ways to find a connection implementation.
* 1. Get the class name from a system property generated in the form of:
* <pre>
* j2me.{connection protocol}.protocol
* </pre>
* 2. Use the class root (see getClassRoot) and the connection
* protocol to dynamically construct a class name in the the form of:
* <pre>
* {class root}.j2me.{connection protocol}.Protocol
* </pre>
* The connection protocol is parsed from the <code>name</code> parameter
* which takes the form of:
* <pre>
* {connection protocol}:{protocol specific part}
* </pre>
* In order to avoid problems with illegal
* class file names, all the '-' characters in the connection protocol
* are automatically converted into '_' characters.
* <p>
* Additionally the protocol specific part is parsed from the name
* parameter and passed to the connection's factory method.
*
* @param name The URL for the connection
* @param mode The access mode
* @param timeouts A flag to indicate that the caller
* wants timeout exceptions
*
* @return A new Connection object
*
* @exception IllegalArgumentException If a parameter is invalid.
* @exception ConnectionNotFoundException If the target of the
* name cannot be found, or if the requested protocol type
* is not supported.
* @exception IOException If some other kind of I/O error occurs.
* @exception IllegalArgumentException If a parameter is invalid.
