MSSQL Data Source ClassNotFoundException
-
I installed Mango on my Windows 10 laptop to start testing. Trying to build an MSSQL data source to database located on my laptop. Seeing the following error:

I am not sure what I am missing here.
Please advise.

Hi eksantrik,
The JDBC driver for MSSQL is not bundled with Mango. You can download it here: https://docs.microsoft.com/en-us/sql/connect/sql-connection-libraries#anchor-20-drivers-relational-access (has links for 6.0 and 6.2 for Java currently). You want the .tar.gz download, it'll have the driver compiled for Java 8, so copy that jar into your Mango/overrides/lib directory and try again.
