HI,

I’m trying to establish a connection with a SQL Server database, but the Process Studio Wizard returns an error as stated below.

Error connecting to database [DATABASE] :com.automationedge.ps.core.exception.ProcessStudioDatabaseException:  
Error occurred while trying to connect to the database

Driver class ‘sun.jdbc.odbc.JdbcOdbcDriver’ could not be found, make sure the ‘MS SQL Server’ driver (jar file) is installed.  
sun.jdbc.odbc.JdbcOdbcDriver

AE Support gave me the solution, I’ll reply here:  
It worked for me.

1. Download the jtds.jar driver [https://sourceforge.net/projects/jtds/files/](https://sourceforge.net/projects/jtds/files/) or use this link [jtds-1.3.1.jar](https://community.automationedge.com/uploads/short-url/4x2tWqig84Jb90Mbo9JFMOX68wY.jar) (310.4 KB)
2. Place it into **process-studio/lib directory**
3. Close process-studio and try again.
