I use @XmlJavaTypeAdapter a lot to manipulate our data model for classes that just don't naturally fit into an XML model (like custom containers and the sort). Seems to be one of the most intuitive and powerful tools in JAXBs toolbox but I can't find anything like it in JPA 1 or 2.
For instance, I can't seem to do the simplest thing with JPA such as take a java.util.UUID and have OpenJPA map it into a STRING. It looks like there is no chance of getting this into JPA 2 since they are in final draft. I just can't imagine such a useful tool *not* existing in a powerful API like JPA, so what gives? Have I missed something fundamental? Thank you, Ryan
