ClassNotFound Exception trying to guess schema

Hi,

 

I'm running Talend Open Studio 6.4.1 and have an issue when I click the Guess schema button on a MSSQLInput component. The job can connect to the database fine when it runs but when I try to guess the schema of a query lookup I get an error java.lang.ClassNotFoundException: net.sourceforge.jtds.jdbc.Driver According to the modules view the jtds module is installed. 

 

I've seen a few similar posts explaining that I should copy the jtds library into the lib folder however this folder is cleaned out when I relaunch open studio. I can also see from the class path that the jtds library is not being included when the guess schema button is pressed. 

 

Can you advise me how to address this?

 

Thanks

Re: ClassNotFound Exception trying to guess schema

Hello,

Your DB connection is configured to use "JTDS"? What's jtds module and MSSQL DB version you are using?

Best regards

Sabrina
