JPA vs JDO - which is more efficient for OneToMany queries?

I'm curious about the trade offs between JDO and JPA. Seems to me that JDO will perform better and be statically typed. For example: Assume there are Customers and Orders.... set automatically, but only when you read the object that contains the inverse field (again) or refresh it. 2) You have to persist ...

using DbUnit with ObjectDb

Are there any examples about how to use DbUnit with ObjectDB? DbUnit requires access to a jdbc connection .. with other providers it's possible to extract the jdbc connection from the EntityManager, e.g. for Eclipselink / Postgres combination you can use the rather long-winded: IDatabaseConnection connection = new DatabaseConnection(((EntityManagerImpl) (em2.getDelegate())).getServerSession().getAccessor().getConnection(), "PUBLIC"); but with objectDb this gives: #1 2011-09-05 10:07 Are there any examples about how to use DbUnit with ObjectDB?

Project runs in Eclipse but not when exported to runnable jar

I have a simple project that performs some stability calculations and displays a scale drawing of a model glider. I decided to use objectdb as a way to persist the values for later retrieval. The project works perfectly well when run from eclipse but nothing opens when I export to a runnable jar and execute that. No windows open, there are no eror dialogs etc. Commenting out all the code related to object db resolves the issue and the project runs, so I'm fairly sure it is something I've done relating to objectdb. ... the result of using this special form of wrapper jar that contains other jar files. Unfortunately I cannot reproduce the ...

Problems down-casting in WHERE clause

I have a family of related types, like this: @Entity class Base { String val1; String val2; }; @Entity class Derived1 extends Base { String val3; }; @Entity class Derived2 extends Base { String val4; };  I'm trying to implement a query which will return all Base objects which have a given string within any of their String-typed fields.  The query I'm using looks somewhat like this: ... attached (I am not attaching the database here because it contains sensitive data). edit ...
