Where are the jobRepository bean and dataSource bean located in Template Project

When the Simple Spring Batch Project is selected from the Template Projects,
the launch.xml file contains 2 beans for dataSource and jobRepository. where are they defined?

Thanks.

I'm assuming you're referring to the template project in STS. If that's the case, both of those beans are defined in the launch-context.xml file found in the /src/main/resources directory of your new project. They are each created using the module specific schemas related to them (jdbc for the dataSource and batch for the jobRepository).
