Here’s what you find when you google for "SQLServer JDBC URL": http://msdn.microsoft.com/en-us/library/ms378428%28v=sql.100%29.aspx

The general form of the connection URL is

jdbc:sqlserver://[serverName[\instanceName][:portNumber]][;property=value[;property=value]]

where:

• jdbc:sqlserver:// (Required) is known as the sub-protocol and is constant.

• serverName (Optional) is the address of the server to connect to. This could be a DNS or IP address, or it could be localhost or
  127.0.0.1 for the local computer. If not specified in the connection URL, the server name must be specified in the properties collection.

• instanceName (Optional) is the instance to connect to on serverName. If not specified, a connection to the default instance is
  made.

• portNumber (Optional) is the port to connect to on serverName. The default is 1433. If you are using the default, you do not have to
  specify the port, nor its preceding ‘:’, in the URL.

Note:

For optimal connection performance, you should set the portNumber when you connect to a named instance. This will avoid a round trip to
the server to determine the port number. If both a portNumber and
instanceName are used, the portNumber will take precedence and the
instanceName will be ignored.
