[resolved] jTDS Driver

Anonymous — Wed, 21 May 2014 19:33:48 GMT

I am having trouble connecting to my MSSQL database. I think the issue is I am missing the jTDS driver. How to I install this external driver into Talend.
I am using Talend Open Studio for Data Integration (5.4.1)

It's finding the driver but, the error that you're seeing is a connection refused error. You need to ensure your SQL Server is using TCP/IP - which it doesn't by default - and that you've configured your correction correctly.

I think it is using TCP/IP...
I went into Sql Server Configuration Manager, went to SQL Native Client 11.0 configuration, then client protocols, I then double clicked on TCP/IP. The Default Port = 1433, and the Enabled = Yes.
So I think SQL server is using TCP/IP, is there another place I need to check?

There could be multiple reasons for connection refused...
The server name is misspelled or the port number is incorrect.
SQL Server is not configured to use TCP/IP. Either enable TCP/IP from SQL Server's Network Utility app or have jTDS connect via named pipes (see the URL format for information on how to do this).
There is a firewall blocking port 1433 on the server.

This didn't have anything to do with TCP/IP not being configured correctly.
My issue was I didn't have the JDBC driver installed correctly. If anybody has the same issue, here is the tutorial I used to get it installed correctly. Once I got it installed correctly I was able to connect to MSSQL without any problems.

I am new to Talend Open Studio and was facing the similar issue "connection refused" while connecting to MS SQL. I went through the below link and it worked for me. The issue is actually related to TCP/IP settings, which we need to make enable in network configuration for the service which we are using. Kindly refer to the below link for further details.
