Hi,
This is really a question for one of the working groups or someone
familiar with the implementation of transactions.

We have our own Object/Relational mapping layer that allows a one to one
object to table mapping with references and collections. This is a code
generator scheme but we have lots of code that builds on this with lots
of applications. Therefore, we have to migrate our code to work in a
J2EE environment or a standard servlet environment. In the J2EE env we
use the supplied data sources and transactions but in the Servlet env we
supply our own. So our stuff needs to implement the proper interfaces so
it looks J2EE spec compliant. (ignoring security, distribution ...)

I already know how to migrate our stuff to use Datasource and
InitialContext but we need some help with transactions. We currently
pass a transaction handle around for transactions that span multiple
objects. I see that we could possibly use a reference table with the
current thread to associate a transaction with a connection.  We need to
make a very rudimentary system so our code uses the transaction
interfaces. I have the JTA spec and APIs for reference.

Could someone give me some pointers to code in the Jonas EJB server that
would help me get started? Any help would be appreciated including
design, implementation and other pointers.

Thanks,
Eric :-)
