I am doing some research on OSGi and persistence and I find the whole Java
persistence story quite confusing and complex. Part of my problem is that I see
lots of frameworks but it is quite hard to see code that really uses those
frameworks. Virtually all tutorials and examples look highly contrived and seem
to totally ignore issues like caching, security and seem to be rather lax
concerning transactions.
I wonder if people in this forum could share with me a typical production
source file showing:
How entities are defined
The persistent use of the entity, i.e. the part where the SQL will be
generated. I.e. places where the PersistenceManager, EntityManager, SQL
generation is used
How results are cached
A single source or class file per issue is best. Adding a small description how
you use persistence (Aries, JPA, JDO, JDBC, etc), the primary issues you face,
and describe your environment is highly appreciated.
I know from my own experience that there is often a feeling that your own code
is not up for showing to others but please send me the raw unadulterated code;
I need to see how it is today, not how you think it should be. Obviously I am
not interested in what the code does or where it is used so feel free to remove
comments (if any!) and change names. I am just looking for a couple of hundred
of real world samples to extract the patterns that are actually popular in our
industry.
Obviously I will not share that code with anyone and treat it fully
confidential. Also would appreciate a little description how you use
persistence in OSGi.
So in this case, do not ask what the OSGi can do for you, but for once, ask
what you can do for the OSGi! ;-)
Please? Come on, it only takes 3 minutes. Send your 4 files to:

Kind regards,
