I've been using Hypersonic as my Database for a while, but as it is very important, that the information is persisted in a real database, I decided to use mysql. This has caused a problem with my beans. As I deploy the application I get the following error:
org.jboss.deployment.DeploymentException: Error while creating table; - nested t
hrowable: (java.sql.SQLException: General error, message from server: "BLOB col
umn 'id' used in key specification without a key length")
The id field is an Object with only one field, which is an int.
Maybe I should just use some automatically generated Primary Key mechanisms instead...
Or use another database...
Or use Integer as my primary key...
Any suggestions?
