How global is package-info.java?

I am having trouble with defining global TypeDef annotations in package-info.java. I have defined three user types for Joda time. I have registered these in package-info.java as so:

Code:

@org.hibernate.annotations.TypeDefs({
  @org.hibernate.annotations.TypeDef(
    name="local_date_time",
    typeClass=JodaLocalDateTimeUserType.class
  ),
  @org.hibernate.annotations.TypeDef(
    name="local_date",
    typeClass=JodaLocalDateUserType.class
  ),
  @org.hibernate.annotations.TypeDef(
    name="local_time",
    typeClass=JodaLocalTimeUserType.class
  )
})

When I try and use a LocalDateTime in my domain objects it is only mapped correctly if I add another annotation @org.hibernate.annotations.Type(type="local_date_time") to each instance. Is this necessary? I was expecting to be able to define my TypeDef once and for it to become this default convertor for LocalDateTime. Is that possible? I am taking this from page 134 of Java Persistence with Hibernate.

Thank you,
Martin

No unfortunately, there is no such mechanism in Hibernate (ie default the type for a given class).
Do you mind posting your type implementation in JIRA (in LGPL). No guaranty but it sounds interesting to autowire them in Hibernate Annotations

Sure I will post them tomorrow when I get in the office. They are tied to mysql at the moment, as it calls a Joda formatter with the mysql datetime format, but they can probably be made database independant by someone who understands hibernate dialects. As JSR310 is likely to be very similar to Joda having one in ready in anticipation could be quite cool. https://jsr-310.dev.java.net/

Edit: Sorry what do you mean by "as LGPL"? Just attach it and state it I am releasing it under LGPL?

year, typically not having a header stating that your code is proprietary to ACME corp and for internal use only :-)

I'm aware of the JSR, I'll need to keep an eye on it.

Hum, using Dialect informations in type is far from trivial, this might need to wait for Hibernate 4 :-(
