Different join types, weaving and spring [message #508860] Wed, 20 January 2010 10:08 Go to next message
Eclipse UserFriend
Hi,

I'm using spring 3.0 and EL 2.0 with jpa 2. Everything was going fine until I tried to map a simple class hierarchy. When I use @Inheritance(strategy = InheritanceType.TABLE_PER_CLASS) it works fine. When I use @Inheritance(strategy = InheritanceType.JOINED) it crashes with thousands of lines of exceptions, I think, because weaving is failing somehow and the implicit OneToOne that implements the join can't find the woven primary/foreign keys.

For now, I can just go with the TABLE_PER_CLASS option, but if the underlying schema is ever shared by other platforms, I would prefer to be using JOINED.

As a follow-up, it appears that in one case this is working for both TABLE_PER_CLASS and JOINED, and in another case it is failing for both. A typical part of the exceptions would be:

The error seems to indicate that weaving did not occur. What is different about the two cases?

Note that Spring does not preload JPA classes to ensure that any weaving can occur before the class is load as required by JEE. This means that if your application triggers the loading of these classes before accessing the Spring context, they will fail to be weaved.

You can try using static weaving, or disabling weaving, or ensure you access the Spring context before triggering the loading of the classes.

I can see nothing different in the two cases. All objects are loaded via objects accessed through spring. The exact same configuration seems to work with hibernate.

Well something is obviously different, my guess would be you are trigger the loading of the class before accessing the Spring context in the one that fails to weave. You can either disable weaving, use static weaving, or ensure you access you context before loading your classes.

Hibernate does not do weaving, so will not have the same issue.
