Solutions

As you can read in this stack trace, the Runtime cannot find the JDBC driver required for connecting to the database. In our example it is a Teradata database.

The solution is to :

- download the required JDBC drivers from the internet,

- install them in the directory stambiaRuntime/lib/jdbc,

- finally restart the Runtime.
