Re: Spring support in Geronimo
Maybe I 'm still miss some point, but I think that's what do the
org.apache.geronimo.transaction.context.GeronimoTransactionManager
[1] of the jencks project. I was in need for it in ServiceMix, because
when using xa transactions, the JBI container has to suspend / resume
transactions.
This is due to the fact the JBI components pull messages from a queue in
their own threads, but the transaction is conveyed on the JBI
message exchange. Therefore, ServiceMix suspends the current transaction
when the message is queued, and resume it when it is dequeued
(in another thread).
The problem is that the only standard way to suspend / resume
transactions is to use the TransactionManager, but
the geronimo implementation does not work well when working on
UserTransaction : all resources enlisted in the user transaction are
managed by the TransactionContextManager and if you call the
TransactionManager directly, the TransactionContextManager is bypassed.
The GeronimoTransactionManager (in jencks project) wraps the
TransactionContextManager and implements both UserTransaction and
TransactionManager. In addition, it allows the use of unmanaged threads
by creating an empty context for the thread where the transaction
is started / resumed, if none exists already. This implementation can
easily be used by the existing spring JtaTransactionManager.
The gbeans written for ServiceMix do use this implementation.
Cheers,
Guillaume Nodet

I think it wants a special lookup class... I wrote one up tonight

If you can come up with some kind of spring app that ought to work

I might be able to come up with something simple... though right now

Anyways, looks like spring needs a Geronimo version like:

I've yet to look at what this puppy does.
And Hibernate needs a Geronimo version of:

Re: Spring support in Geronimo
FYI so far so good with your spring txm bridge. Though I did see some strange spring errors when passing the gbean name in as a constructor-arg... But for testing I created a subclass to set those params for now. Still can't tell how well the hibernate lookup works, hopefully I can get to that today.

Btw why did u integrate the spring tm? (like any special features that it provides) Is it better than the default Geronimo transaction manager? (I have heard that you can use spring tm standalone, may thats what u did, pls correct me if I am wrong) Regards, Rajith.

I did read David Jencks comments on the JIRA issue, but couldn't grasp the overall context of the sping involvment within G. So I really appreciate a bit more background and more specific information on the topic.I know that it is possible to run a spring app started from a servletinit method in geronimo (namely jetspeed2).We'd like to expose our services such as the transaction management and connectors in spring. I don't know much of anything about Springso I just barged ahead and implemented a spring-tm to geronimo-tcmadapter. If anyone knows how to determine how much it works, pleasehelp out :-) There's also the jencks project which has a different purpose. Theyare not running anything in the geronimo kernel, but rather startingthe geronimo jta and j2ca components in spring. I don't think that those components will be very useful for exposing components runningin the geronimo kernel in spring, but I could be wrong.thanksdavid jencks thanks, Rajith
