Integration JBoss with JackRabbit and SpringModules

[junglika]

Hello.

I am trying to run jackrabbit in a transactional environment such as
jboss because i need JTA Transaction(i'm working with DataBase and jackrabbit in the same transaction). The application server was configured more or less as described in http://wiki.apache.org/jackrabbit/JackrabbitOnJBoss




- removed jcr-1.0.jar from jackrabbit-jca-1.0.1.rar
- download the latest jcr-1.0.1.jar and copied it to the
jboss/server/${profile}/lib folder
- copied the modified jackrabbit-jca-1.0.1.rar to
jboss/server/${profile}/deploy
- adjusted jcr-ds.xml to jackrabbit-jca-1.0.1.rar
(<rar-name>jackrabbit-jca-1.0.1.rar</rar-name>) as well as
homeDir and configFile
- copied the modified jcr-ds.xml also to the
jboss/server/${profile}/deploy folder




<connection-factories>
<tx-connection-factory>
<jndi-name>jcr/local</jndi-name>
<xa-transaction/>
<rar-name>jackrabbit-jca-1.0.1.rar</rar-name>
<connection-definition>javax.jcr.Repository</connection-definition>
<config-property name="homeDir" type="java.lang.String">/tmp/jackrabbit</config-property>
<config-property name="configFile" type="java.lang.String">/tmp/repository.xml</config-property>
</tx-connection-factory>
</connection-factories>


I use springmodules 0.5 and use DAO support to acces to repository, when jboss try to make a commit throw the next Exception:



2006-07-20 15:41:52,824 ERROR [org.apache.jackrabbit.core.XASessionImpl]

I have no idea how this can be done. Any ideas? :confused: Did any get jackrabbit running in JBoss whith springmodules-jcr-0.5.jar and jackrabbit-jca-1.0.1.rar????

Thanks

I guess you'll find more answers on the Jackrabbit mailing list; SM Jcr support support doesn't handle transactions when dealing with JCA (as you can see from the stracktrace).
If you find any answers, please post back - it might help others.

The problem appears when the spring-modules library does a session logout. I sended a patch to jackrabbit jira to disable this method, because the session must be closed when transaction finishes.

[Costin Leau]

Let me know what the outcome is - we could add some workaround maybe inside the JCR module to prevent the problem from occuring.
You could also raise an issue on JIRA for further reference.
Thanks!

Hello again :rolleyes:

I had seen that in days ago appear a new version of jackrabbit, but not include the modification that i considerer that is good.

See
https://issues.apache.org/jira/browse/JCR-463

The Spring modules fail when in "releaseSession" method (SessionFactoryUtils) invoke a "session.logou()" in jca transaction:

public static void releaseSession(Session session, SessionFactory sessionFactory) {
if (session == null) {
return;
}
// Only close non thread bound Sessions.
if (!isSessionThreadBound(session, sessionFactory)) {
logger.debug("Closing JCR Session");
session.logout();
}
}

The isSessionThreadBound method don't know if i use jca transaction.

I think that this the error but if in jackrabbit library no change de code in springmodules a don't know that make.

Thanks

can you please create an issue on JIRA? it's a lot easier to keep track of these problems.
Thanks.

[junglika]

where do you think that i must create a issue, in jackrabbit or in springframework, (i add a new issue in jackrabbit days ago, see: https://issues.apache.org/jira/browse/JCR-593)

If you'd like the workaround to be implemented inside Spring Modules, then the Spring Modules JIRA.
