Hi Aaron,
The code is great. IMHO, below are the things that we need to be done for getting this big patch applied.
1. axis2-war module test case code is out-of-update, it still refers to the old dao package, like 'org.apache.ode.bpel.dao.", It seems to me that we didn't compile and run test case for this module, do we? 2. use the buildr build to check if we can get it build with this. I know this might be the hard part here, unless you are familiar with buildr. We may ask other devs here to see if they are interested picking up this task. But I will try to build with that firstly to see how many problems we have right now.
BTW, this refactoring work is so great that I am thinking that migrate it into Apache ODE 1.x branch, how much effort do you think it would cost for this move? We are trying to add the clustering support for 1.x code base, one first thing here would be to implement the JPA based DAO impl for scheduler module.
Regards Jeff

Hi Jeff,
I completed the new JPA based SimpleScheduler DAO implementation. Now there is JDBC based implementation (refactored original delegate implementation), a JPA OpenJPA implementation (default now), and a JPA Hibernate implementation. I did not create a new non-JPA Hibernate implementation since to my knowledge JPA will be the persistence implementation of choice for ODE.
One last think that needs to be done is to update the JPA DDL module to include additional indexes in case the SQL generator does not index everything that needs them.
Also as part of my refactoring I added transactional operations to the DAOConnection interface so that it can hide the underlying transactional mechanism in case JTA is not used. To me it makes the DAO usage more concise. Perhaps in the future the engine and runtime code can be modified to utilize the DAO transactional operations instead of directly manipulating the JTA transaction manager.
Please take a look and let me know what more needs to be done for the JPA refactoring effort.
Regards,
Aaron
