EclipseLink Cache Coordination

[Vano Beridze]

Hello,

I have an application which primarily consists of RESTful web services that communicate with Stateless session beans that manipulate data using JPA.
I use EclipseLink as Persistence provider.
My task is to run the application in a clustered environment.
I followed the guide to create a simple cluster
http://blog.payara.fish/payara-server-basics-creating-a-simple-cluster
After enabling Hazlecast, I checked and everything except JMS availability was enabled. I enabled it too and Saved the configuration.
I have created JMS resources as indicated in
https://wiki.eclipse.org/EclipseLink/Examples/JPA/CacheCoordination
But when I deploy the application in the cluster I get the following error:

Error occurred during deployment: Exception while preparing the app : Exception [EclipseLink-28019] (Eclipse Persistence Services - 2.6.4.qualifier): org.eclipse.persistence.exceptions.EntityManagerSetupException Exception Description: Deployment of PersistenceUnit [test_clustertest_war_1.0-SNAPSHOTPU] failed.

What am I missing here? When I use asadmin list-jms-resources for cluster members everything is listed.

Can you look up the factory from any application?  Do you have resource linked with the factory connection pool?

[Vano Beridze]

I've created test application which creates the MDB bound to the same topic I indicated for Cache coordination.
There is a servlet which injects Stateless session bean which injects Factory and Topic I used for Cache coordination.
I've deployed this application and it works fine. I see in the log that message is received by MDB.

I'm attaching this test application project.

What do you mean by "Do you have resource linked with the factory connection pool?"

I'm also attaching screenshots of my configuration and server log excerpt.
I can provide any part of the config if needed.

I would say domain.xml would be very helpful in this case,

as well as any libs in your <domain>/lib directory

 Attaching domain.xml
in domain1/lib I've got empty folders and PostgreSQL JDBC driver: postgresql-42.1.4.jar

Sorry about the long delay. Payara will be publishing a blog about cache coordination shortly.

It should give you a direction on how to set this up
