  • 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:

    My driver class setting is as follows: com.microsoft.sqlserver.jdbc.SQLServerDriver

    My connection string is as follows: jdbc:sqlserver://127.0.0.1:1433;database=Bisson;integratedSecurity=false;

    I am not sure what I am missing here.

    Please advise.

    Thanks,


  • 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.
