Returns the existing connection with the MobiLink consolidated database as a JDBC connection. This connection is the same
connection that MobiLink uses when executing SQL scripts for this synchronization.
This connection must not be committed, closed or altered in any way that would affect the MobiLink server use of this connection.
The connection returned is only valid for the lifetime of the underlying MobiLink connection. Do not use the connection after
the end_connection event has been called for that connection.
If an error occurs binding the existing connection as a JDBC connection then it throws java.sql.SQLException
If a server connection with full access is required, use ServerContext.makeConnection().
