[jetty-users] Jetty, Atomikos, Hibernate, XA - NoClassDefFoundError and other exceptions
|
Hi guys
My system:
Jetty 6.1.22
Atomikos Essentials 3.6.0
Hibernate 3.3.2
Linux
JDK 6 u18
How properly configure them to make hibernate lookup the Atomikos TM ?
===> The relevant documentation:
http://docs.codehaus.org/display/JETTY/JNDI#JNDI-tx
http://www.atomikos.com/Documentation/HibernateThreeStandalone
What I did:

If I copy the lib/transactions-essentials-all.jar to WEB-INF/lib/ it works !
Obviously I dont want to put the atomikos jar as my application
dependency. Nor copy the whole hibernate jars into jetty/lib.
I see the atomikos library (server scoped) cannot see the hibernate
library (application scoped).
I changed the persistence.xml to exclude the hibernate transaction
configurations (manager_lookup_class, factory_class,
current_session_context_class) to let hibernate configure itself.
But it threw the following exception (only the relevant part)
javax.persistence.PersistenceException: [PersistenceUnit: mypu] Unable

Configuring only the hibernate.transaction.factory_class to
org.hibernate.transaction.JTATransactionFactory, throws the exception
org.hibernate.TransactionException: Could not find UserTransaction in
JNDI [java:comp/UserTransaction]

I did a bit of searching on the internet, but no success.
==> A test case is available to show the issue, download at
http://www.claudius.com.br/hib-jetty-atomikos-bundle.tar.gz
Inside you find a war file ready to deploy and the source code:
hib-jetty-atomikos.war
hib-jetty-atomikos (directory)
You need to create a jdbc/pgsql resource at etc/jetty-plus.xml, see
the example at the top of the post.
Sorry for the long post, but there is a issue and a test case, I hope
someone can take a look at this.
Cheers
