Wildfly with Hibernate and Infinispan

[tollrakesh]

Hi,

I'm trying to port my spring based application which was previously working with Hibernate4+EhCache+Spring4+Tomcat8 configuration to Hibernate4+Infinispan6+Spring4+WildFly8.

Now in this context, I downloaded the new wildfly 8.2 and without any configuration changes to infinispan, I set the hibernate properties as below

hibernate.cache.infinispan.cachemanager=java:jboss/infinispan/container/hibernate
hibernate.cache.region.factory_class=org.hibernate.cache.infinispan.JndiInfinispanRegionFactory
hibernate.cache.use_second_level_cache=true
hibernate.cache.use_query_cache=true

With this I get the below exception during deployment (WildFly standalone mode). Expecting to use the local-cache "entity".

Caused by: java.lang.ClassCastException: org.jboss.as.clustering.infinispan.DefaultCacheContainer cannot be cast to org.infinispan.manager.EmbeddedCacheManager

When I try to assign the "entity" local-cache itself a JNDI name and then point the hibernate cachemenager to this new JNDI, then I get the below error

Caused by: java.lang.ClassCastException: org.jboss.as.clustering.infinispan.DefaultCacheContainer$DelegatingCache cannot be cast to org.infinispan.manager.EmbeddedCacheManager"}}

I was unable to export org.infinispan itself as a wildfly module, with the hope that I could generate the EmbeddedCacheManager from it.

I'm new to JBOSS/WildFly family. So need your help in configuring this system.

Thanks,

Rakesh

You should use WildFly's hibernate region factory, which integrates with the Infinispan subsystem.

e.g.

hibernate.cache.region.factory_class = org.jboss.as.jpa.hibernate4.infinispan.InfinispanRegionFactory

You can omit the "hibernate.cache.infinispan.cachemanager" property, as it is not relevant to WildFly's region factory implementation.

Hi Paul,

Thank you for the reply. I think I tried this as well along the way. In this case, I'm not able to locate that class under WildFly modules.

When I try to  use it directly, I get the class not found exception

Caused by: org.hibernate.HibernateException: could not instantiate RegionFactory [org.jboss.as.jpa.hibernate4.infinispan.InfinispanRegionFactory]

Is there any specific library I should be importing?

Thanks in advance.

What happens if you don't set hibernate.cache.region.factory_class?  Is your application using JPA or the native Hibernate api?  For JPA, org.jboss.as.jpa.hibernate4.infinispan.SharedInfinispanRegionFactory is used.  During deployment, WildFly sets the factory_class automatically if hibernate.cache.use_second_level_cache is set to true.

I think he's using the hibernate API.  I would bet that the class visibility issue is due to bundling the hibernate jar in the deployment, rather than exporting the WildFly's hibernate module to the deployment.  See: https://docs.jboss.org/author/display/WFLY8/JPA+Reference+Guide#JPAReferenceGuide-UsingtheInfinispansecondlevelcache

smarlow There's a mistake in the documentation - the "hibernate.cache.infinispan.cachemanager" property should be removed from the sample configuration since is not read by jipijapa's region factory implementation.

Hi Paul.. the issue seems to be fixed. I started to get passed this issue but started to face another one as below

Spring IllegalStateException: A JTA EntityManager cannot use getTransaction()

I'm currently researching on that issue. Migration seems to be painful

There are some notes on migration of Spring applications.   Also, http://snowdrop.jboss.org might be interesting for you.
