Hi thesti,

I had the same problem, that made me waste an entire day looking for a solution.
The problem, in my case, was the instance name, using a named instance, like this

jdbc:sqlserver://SERVERNAME\INSTANCE:1433;databaseName=TESTDB

I changed my instalation, so the server isn’t named, and just accept a connection in the form:

jdbc:sqlserver://SERVERNAME:1433;databaseName=TESTDB

and I got the connection working.

Hi, Thesti

The error message states that it couldn’t connect to the SQL Server so there must be something wrong. I suggest you try to telnet to port 1433 to re-verify if the SQL Server is accepting request or not.

If telnet can connect, then try to change hostname on the connection string to an ip address of your computer.

If it still doesn’t solve the problem, can you show your source code?

hi Linglom,

i’m using this driver “Microsoft SQL Server JDBC Driver 2.0″ to connect to SQL Server 2000 from Netbean 6.7.1

i got this error

“Unable to add connection. Cannot establish a connection to
jdbc:sqlserver://localhost:1433;databaseName=Northwind using
com.microsoft.sqlserver.jdbc.SQLServerDriver (The TCP/IP connection
to the host localhost, port 1433 has failed. Error: “connect timed out.
Verify the connaction propoerties, check that an instance of SQL
Server is running on the host and accepting TCP/IP connections
at the port, and that no firewall is blocking TCP connections to the port.”.).”

though that i’ve verifed from Server Network Utility that the TCP/IP protocol is enabled and is listening on port 1433.

i can connect to the server through query analyzer though. i wonder what’s wrong?

Thank you.

Ok, in Netbeans I have a proxy configured and it could not connect through that proxy. Once I turned the proxy off, it connected just fine.

I am getting the following error:

The TCP/IP connection to the host has failed.
java.net.SocketException: Malformed reply from SOCKS server

My connection string is:
(0.0.0.0 = is the fake ip address to the server for this post)
(***** = is the fake password for this post)

jdbc:sqlserver://0.0.0.0:1433;databaseName=ITAssetsDB;user=sa;password=*****;

Hi, Vikash
Is there any error message when you established a connection to the SQL Server?

Hi,

Thanks for the nice post. My issue is I can create connection to MS SQL Server 2005 through the runtime window in netbeans 6.5,1, but it doesn’t show any tables nor does running queries help. I need to use hibernate in my project and that requires this connection to work properly. Am I missing something? Thanks

Hi, Alex
About environment in the tutorial: Windows XP SP2 with NetBeans 5.5 and SQL Server 2000 SP4 on the same computer.

I suggest the best way is to develop on the same computer first (connect to SQL Server on the local machine).

my problems are still unsolved, or assuming that it works in your PC, can i have the spesification of the PC such as what is the OS, what is the version of SQL Server (2000 or 2005), and other requirements. So i can try from zero. Thanks alot.
