Connecting To MSSQL Server 2000 Using JDBC

Hello,

I am developing an application which needs JDBC connection to a Named Instance of SQL Server 2000 (other than default instance). I am facing problem in this regard as my code gives an exception "Time Out" or "Connection Failed". However it works fine with the default named instance...The main driver class is "com.microsoft.sqlserver.jdbc.SQLServerDriver"

and Connection URL is

"jdbc: sqlserver://localhost;instanceName=Testing:1432;databaseName=testDB;"



It gives the exception that Unable to connect to named instance....



Please if any one have any knowledge in this regard....do let me know....I have read an article on MSDN according to which on MS SQL Server 2000 the named Instance other than default can be accessed only through named pipes.

http://msdn2.microsoft.com/en-us/library/aa224779(sql.80).aspx



if some body can tell me Connection string for JDBC driver which utilizes named pipes...the it will be very help full for me.........any help from MSDN Experts is really appreciated...

Thanks
