Hi
The bit in brackets for the jndi name is an ldap filter (just like a service
lookup). What you want is
(&(osgi.jndi.service.name=jpa/jtaStagingDb)(xa=true))
You don't need to add <entry key="xa" value="true" /> to your service
export, that gets added by the transaction wrappers bundle when it re-exports
your service (to let you know it's the wrapped one).
I think the easiest setup for you is to use:
<jta-data-source>osgi:service/javax.sql.XADataSource/(osgi.jndi.service.name=jpa/jtaStagingDb)</jta-data-source>
<service id="xaDataSource" ref="stagingXADataSource"
interface="javax.sql.XADataSource">
<service-properties>
<entry key="osgi.jndi.service.name" value="jpa/jtaStagingDb" />
</service-properties>
</service>
Regards,
Tim

While you are still on-line, may I ask
you for some clarifications;
persistence.xml: the following apparently doesn't work:
<jta-data-source>osgi:service/javax.sql.DataSource/(osgi.jndi.service.name=jpa/jtaStagingDb
xa=true)</jta-data-source>
datasource blueprint? : neither this
<service id="xaDataSource" ref="stagingXADataSource"
interface="javax.sql.DataSource">
<service-properties>
<entry key="osgi.jndi.service.name"
value="jpa/jtaStagingDb" />
<entry key="xa" value="true" />
</service-properties>
</service>
What's the correct syntax?

I'll check with Manning about the discount code, I wasn't aware

Hi, Timothy.
Thank you, your message arrived very handy just when I am
wasting my Saturday night (UTC +9.30) in another attempt to
make JTA work.
For a more than a couple of week I put it on the back burner,
while doing other tasks.
I will look at your suggestions and also will purchase the
book - thanks for the generous offer. I had only green paper
and the source code so far.
So, I may want to ask for an autograph from the author :).
My OSGi crash course is lasting couple of month by now, so I
had only chance to digest (albeit still suffering heartburn :)
) "OSGi in Action".
Though I realized at rather early stage that I have to deal
with OSGi enterprise as far as JPA/JTA container support
concerned.
Kind regards,
Anatoly
PS "The coupon code you have entered has expired" I
received this message when applied the code.

Hi,
I'm afraid I haven't had time to do a full review, but from
the log I see that your datasource services are both being
registered by blueprint using the DataSource interface.
Unless you're enlisting the JTA datasource with transactions
yourself then this looks like the source of the problem. If
you want the Aries runtime to do the enlistment then you
need to register the datasource as an XADataSource.
There are then two options:
1. You can let the transaction wrappers bundle do the
enlistment and add (xa=true) to your JTA-data-source jndi
name
2. You can let the JPA container do the enlistment by
changing the JTA-data-source jndi name to use XADataSource
as the interface. This will only work for Aries JPA 1.0 and
higher.
If you are after more information about setting up OSGi
applications with JPA then there's a whole chapter about it
in Enterprise OSGi in Action, along with chapters about
tools, testing, web applications and remoting. You can get
it at http://www.manning.com/cummins
and get 37% off using the code eosgi37.
I hope this helps you get set up ok.

Tim

Thank you, Timothy.
I use the current release 1.0.0 of aries
http://aries.apache.org/downloads/currentrelease.html
I have attached the blueprint context files - blueprint
seems to be the only way at the moment to use declarative,
AOP style, transactions support.
And the test class invoked in blueprint-test.xml
blueprint-datasource.xml -- blueprint context of the
database bundle
blueprint-employee.xml - blueprint of employee bundle
blueprint-test - blueprint of the integration test
routines bundle
persistence-jta.xml - the JPA/JTA persistence unit
configuration
I must confess, that I don't know what is auto-enlisting
datasource.
Regards,
Anatoly
PS I also attached the log of the test with the
deliberately induced sql error. The rollback is announced,
but all the insert statements, except for the offending
one, still get committed, including the cascade
insertions.
So, no actual rollback is performed.

Hi Anatoly,
I'd be interested in seeing the configuration for the
transactions that failed to roll back, and in knowing
what version of Aries JPA you were using. If you don't
give the JPA container an auto-enlisting datasource then
you can end up with non-transactional behaviour.
This is why we have the transaction-wrappers bundle.
