Problems with Session and transaction handling?

Read this: http://hibernate.org/42.html

Hi,
i have un into a crazy problem. I have the same schema for three databases. So i have the only one Java Objects defined for a table even though it is replicated in the other dataases. When using the EnityManager outside a container this is no problem. However how do i go about it when using a container? Do i have to write seperate classes for each database or is there some other way of doing it?

Hmm ... jar those domain classes and reference that jar within 3 different persistence.xml meta data files.

U mean a single jar file but 3 persistence.xml files ?

Single domain POJO jar and 3 ejb3 persistence jars - each referencing that domain jar as jar of entities.

Can u please explain what do you mean by ejb3 persistence jars? Can u give an example for the same..

Ever worked/deployed new ejb3 app (simple conf, no triple schema, ...)?

yes, I have made EJB3 applications but that were using only 1 persistence.xml

So what's the problem then - simply triple what you did - but just with one domain jar - which is referenced in persistence.xml.

app.ear
- domain.jar (entities)
- ejb1.jar (META-INF/persistence.xml)
- ejb2.jar (META-INF/persistence.xml)
- ejb3.jar (META-INF/persistence.xml)

Ok, if persistence.xml doesn't suppport referencing jars as entites - I know H3 does - so you can use orm.xml to do that.

Ok Thanks...i ll try out the same and get back to you.
