Hi all, We're migrating from a Key/Value system to MySQL for some components of our system for easier administration and maintenance. As part of this migration, we need to retain the time UUIDs that have been generated for primary keys. I'm having a hard time mapping this. I have the following.
@Id @Column( columnDefinition = "BINARY(16)", length = 16 ) private UUID id; However this always seems to fail. I'm on the latest MySQL version 5.6.16 GA and Open JPA 2.2.2 I've found this old thread, but it's not quite what I'm looking for. I'm really struggling to find the documentation on how to declare and implement custom type converters. Converting a UUID to a binary array of length 16 is trivial, as is creating a new UUID instance from those bytes. I'm just not sure how to plug in to the JPA framework to make it happen. Any advice would be greatly appreciated. Thanks, Todd
