eliminating the persistence layer in ode
Hi,
I'd like know if I can use ode as a plugin in an OSGI container, and is
there any tutorial on that
I have import the Source code of ode (trunk) in eclipse, to study if it will
be possible to eliminate the persistence layer and replace it by spring jdbc
for example, so would I just implemente bpel-dao..are there other parts in
the code that call or use hibernate (or whatever the implementation is)
thanks you in advance

Hi,
Sorry but it steal not too clear for me!
in fact,Can I get the scenarios of tests that I will verify them to ensure
the non-regression of ode?
+ in fact I'd like also to know how ode manage hibernate(sessions,
caches..)..with osgi many bundles need to use the DB..they could all use
their own hibernate session factory..in my case other bundles (of the
existing application) don't use hibernate...but just spring jdbc..so if I
will integrate ode..I don't know how it will interact..
any guidelines or explanations are welcome..I need your experiences!
thank you

We also have an in memory DAO layer. Of course it implies some additional
restrictions on your processes...

Thank you for replying, in fact I don't like to use any ORM, because there
are lot of problems with ORMs if database server is distant, so if I can
modify this part where can I find the guidelines of tests to avoid code
regression while modifying the source.
thank you

Hi,
AFAIK the WSO2 guys maintain an OGSi-fied version of ODE. Regarding the
DAOs: There is no static dependency to Hibernate, in fact Ode ships with
two different implementations for the DAO layer (Hibernate and openJPA).
Best,
Tammo
