This was in addition to changing your datasource blueprint to:
<service id="xaDataSource" ref="stagingXADataSource"
interface="javax.sql.XADataSource">
<service-properties>
<entry key="osgi.jndi.service.name" value="jpa/jtaStagingDb" />
</service-properties>
</service>
wasn't it?

... my progress so far :
With this line in the persistence.xml
<jta-data-source>osgi:service/javax.sql.DataSource/(&(osgi.jndi.service.name=jpa/jtaStagingDb)(xa=true))</jta-data-source>
Yet, the result is still as before: all the participating transactions
apart from the offending one got commited.
My only choice is to MsSql, and the problem might be with the driver.
Of course, I might try to build the test case with other database to
verify this.
As for the latest suggestions to tweak the config.ini ... This one is
generated (Eclipse default option: generate with default content) and
doesn't bother to specify the org.osgi.framework.system.packages property.
I definitely not going to create that listing manually - it's crazy.
At this very moment I tend to point finger to MsSql ...

Anatoly

Hi,
Have you set up your system packages to prevent people getting
wired to the split package in the JDK?
If you look at
https://svn.apache.org/repos/asf/aries/trunk/samples/blog/blog-assembly/src/main/filtered-resources/configuration/config.ini
You can see that the org.osgi.framework.system.packages property
sets a mandatory partial=true parameter on javax.transaction and
javax.transaction.xa

I tried the option 2) - I recollect tried it some time before.
And now it also doesn't work - problem with MsSql driver
Caused by: java.lang.LinkageError: loader constraint violation in
interface itable initialization: when resolving method
"net.sourceforge.jtds.jdbcx.JtdsXAConnection.getXAResource()Ljavax/transaction/xa/XAResource;"
the class loader (instance of
org/eclipse/osgi/internal/baseadaptor/DefaultClassLoader) of the
current class, net/sourceforge/jtds/jdbcx/JtdsXAConnection, and
the class loader (instance of <bootloader>) for interface
javax/sql/XAConnection have different Class objects for the type
javax/transaction/xa/XAResource used in the signature

at
org.apache.aries.transaction.jdbc.XADatasourceEnlistingWrapper.getConnection(XADatasourceEnlistingWrapper.java:63)
at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
So, the ball on the MsSql driver side? The bad news is that I am
not aware of any other driver, and that one worked perfectly well
with Spring framework JTA declarative support in non-OSGi environment.
What do you think?

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.
Regards,
Tim

Subject: Re: Aries eclipselink.adapter
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.
