We use Joda Time in the project, and all dates in @Entities are of type org.joda.time.DateTime. We use Joda-Hibernate user types for mapping it to DB.
BUT: I'm tired of declaring the field type on every such date:

From what I've found, I can declare global alias using @TypeDef, than I could make it a bit shorter, e. g.:

But still it's horrendous amount of pointless code. How can I globally tell Hibernate "use this user type converter for fields of that type"? So that I finish with:

I can't find a way to do it... but it's crazy too much to assume it can't be done...

Does it mean it really can't be done? It's hard to believe... looks like very very basic requirement... I should probably craete a Jira issue about it?

What happended to an active community? Anyone from the Hibernate-team care to comment on this? I agree that this kind of functionality really helps and should be part of the JPA spec (which I think JPA-2.1 actually addresses).

still an issue, after two years...

i just don't want to redeclare my joda type on each and every field. there is also the risk some colleague might not be aware of doing this, and then we've got a runtime error, sweet...

BTW: is it really necessary to send me my password in plaintext via mail for the account activation? this really sucks, as i guess this forum is storing my password in cleartext :(

This is actually possible using Hibernate-4.

Have this in your pom (version 3.0.0.CR1):
<dependency>
<groupId>org.jadira.usertype</groupId>
<artifactId>usertype.core</artifactId>
</dependency>

Set these properties
<prop key="jadira.usertype.autoRegisterUserTypes">true</prop>
<prop key="jadira.usertype.databaseZone">jvm</prop>


And you're good:-)
