Re: [Springframework-developer] TopLink support

[Juergen H. <ju...@in...>]

Well-spotted, I have deliberately kept this out up to now, because TopLink
has its own Connection acquisition rules (by default lazy; within a write
transaction, not before actual commit).

I've spent some time today to research this a bit further: for a read-write
transaction, TopLink can be forced to start the database transaction early,
which makes it stick with a single JDBC Connection upfront. That JDBC
Connection can be retrieved (through some API hoops), so I've added support
for exposing it as transaction for JDBC access code. A DataSource needs to
specified on TopLinkTransactionManager's "dataSource" property to enable
this.

To be committed later today :-)

Just wondering, is it possible to mix TopLink DB access and straight JDBC
use in the same transaction, like with the HibernateTransactionManager? If I
understand the JavaDoc this doesn't seem to be the case?
