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
net.sourceforge.jtds.jdbcx.JtdsDataSource.getXAConnection(JtdsDataSource.java:116)
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?

I'll check with Manning about the discount code, I wasn't aware that
it had an expiry date.

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

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.
