Class not found error trying to connect to MSSQL instance

[Anonymous]

I'm getting this error when trying to enter new connection data. I assume I am supposed to download it, but where do I put it? I tried the %CLASS_PATH% directory, no luck.
Thanks in advance.
Connection failure. You must change the Database Settings.

Yes, I am using 64-bit Windows 8 OS.
As suggested I moved the jtds-1.3.1.jar file from <StudioPath>/configuration/lib/java to <StudioPath>/lib/java.
Then when I started TOS and tried to create a connection, the studio asked me to download the jtds-1.2.5 jar, which it placed in the <StudioPath>/configuration/lib/path directory.
And then I got the same exception. So your solution to place the JAR file in <StudioPath>/lib/java did not work.
Any other solution?

Hi,

Then when I started TOS and tried to create a connection, the studio asked me to download the jtds-1.2.5 jar, which it placed in the <StudioPath>/configuration/lib/path directory.

Did you go to  Window-->Show View-->Talend-->Modules to see if your jtds-1.2.5 jar is installed? If not, could you please try to install it into studio by manul?
Have you already tried to use studio 6.1.1 to see if this issue repro?
Best regards

I have tried with Studio 6.2 and the problem is not reproduced.
I checked the module/JAR is already installed, check the screenshot I have attached.
I also tried installing manually by selecting the jtds-1.3.1.jar file but the modules list has not got updated.

Hi,
We can not repro your issue on V 5.6.2.
Is it Ok with you when you using 6.2.0M1? Could you please try to copy jtds-1.2.5 jar into  <StudioPath>/lib/java also to see if it works?
Best regards
Sabrina

As you are not able to reproduce this issue and the higher versions do not face the same issue, I will consider this issue as resolved.
