JDBC Adapter connection config

Hi all

I try to configure a JDBC Adapter connection to a MySQL database. When When I try to enable the connection I get the error:

Error encountered
[ART.118.5042] Adapter Runtime (Connection): Unable to enable connection resource D106Exercises.adapters:D106Adapter2.
[ART.118.5036] Adapter Runtime (Connection): Unable to configure connection manager.
Invalid index!

Thank’s for any idea.

Verify that all three server connection pools has been setup properly using ISAdmin console version 6.0.1
