[dali-dev] a few more Dali questions (extending entity generation, etc)

[Tom Mutdosch <tommut@xxxxxxxxxxx>]

Hi there,

I've got a fresh batch of Dali questions. :)

1) Is there a way when generating entities to tell Dali that I want my entity 
classes added into the class list in the persistence.xml?  For performance 
reasons, I want to have all of my classes listed there; also for Java SE 
scenarios this is a necessary requirement.

2) I know previously Neil mentioned that in an upcoming release that Dali would 
allow you to have your connection information placed into the persistence.xml 
for you.  Will there be some way to decide between a datasource or a 
driver-managed connection?  That is, if I have a datasource set up, I would just 
want the jta-data-source written to the persistence.xml; otherwise I would need 
all of the individual provider properties written out detailing my connection 
info.  Will these scenarios be handled?

3) I'm interested in extending Dali entity generation to handle things like 
generating additional constructors in the entities, or to generate some default 
namedQueries.  I believe that I can hook into the Entity Generation framework 
somehow and perhaps provide my own subclassed Entity Generator.  Is this 
currently possible?  It would be nice to be able to specify my EntityGenerator 
in a plugin and then perhaps be able to choose that from a list of generator 
providers (or set it up programatically beforehand) and have the entity 
generation wizard call by EntityGenerator.  Is something like this currently 
possible?

4) Along these same lines, if I want to update the model before generation to 
add things like setting up an OCC column or additional relationships, can I do 
so?  That is, is this entity model exposed so I can update it so that it will 
generate what I want?


If anyone can help answer these, or let me know if they should be opened as 
feature requests, I'd appreciate it.
Thanks
Tom
