Hi Mary - I had read the wiki & watched the best practices video but thanks for the note, The Jaspersoft instance was loaded using the cloud formation stack as recommended in the launch video and the database created in the same account RDS database is MYSQL Data Source in Jaspersoft is of type 'AWS Data Source' The AWS Settings are 'Use EC2 Credentials' The database is listed in the AWS DataSource under Amazon RDS The database driver is 'com.mysql.jdbc.Driver' when I try to test the connection I get the' VPC ID does not exist error'.
