setPortNumber Method (SQLServerDataSource)
Sets the port number to be used to communicate with SQL Server.
The port number is the TCP/IP port number that is used when opening a socket connection to SQL Server. If the portNumber property is not set, the getPortNumber method returns the default value of 1433.
The setPortNumber method does not do any range checking on the port value passed in. You can pass a port number that is not valid, like 99999, without triggering an error.
