    Configuring Infinispan as L2 Cache, deployment error, jndiName

      Hi,

       

      I'm trying to configure JBoss 7.1 to use Infinispan as L2 Cache as per https://docs.jboss.org/author/display/ISPN/Using+Infinispan+as+JPA-Hibernate+Second+Level+Cache+Provider and http://www.mastertheboss.com/hibernate-cache/using-hibernate-second-level-cache-with-jboss-as-5-6-7

       

      I am running my app in domain mode. When I deploy my app the JNDI lookup for cache manager always fails whether I use

      value="java:CacheManager" / or value="java:CacheManager/entity" or  value="java:jboss/infinispan/hibernate"/>.

       

      So none of the cache's are available via JNDI so I tried adding the JBoss  recommended entity cache (which is the invalidation cache?) to JNDI. I tried it like this (I had to add jboss into teh JNDI name unlike theinstructions as Jboss gave an error unless present)

       

       

      {code:xml}<cache-container name="hibernate" default-cache="local-query">
                          <transport lock-timeout="60000"/>
                          <local-cache name="local-query">
                              <transaction mode="NONE"/>
                              <eviction strategy="LRU" max-entries="10000"/>
                              <expiration max-idle="100000"/>
                          </local-cache>
                          <invalidation-cache name="entity" mode="SYNC" start="EAGER" jndi-name="java:jboss/CacheManager/entity">
                              <transaction mode="NON_XA"/>
                              <eviction strategy="LRU" max-entries="10000"/>
                              <expiration max-idle="100000"/>
                          </invalidation-cache>{code:xml}

      but I get an error like this

       

       

       
       
      Caused by: javax.persistence.PersistenceException: Re: Insert Infinispan as Cache Layer above existing Hibernate/MySQL layer Unable to build EntityManagerFactory
      Caused by: org.hibernate.cache.CacheException: Unable to start region factory
      Caused by: java.lang.ClassCastException: org.jboss.as.clustering.infinispan.DefaultEmbeddedCacheManager$DelegatingCache cannot be cast to org.infinispan.manager.EmbeddedCacheManager
       
       
       
       
      so then i tried to give the CacheContainer a JNDI entry like this:
       
       
       
       
      {code:xml}
      <cache-container name="hibernate" default-cache="local-query" jndi-name="java:jboss/CacheManager/entity">
                          <transport lock-timeout="60000"/>
                          <local-cache name="local-query">
                              <transaction mode="NONE"/>
                              <eviction strategy="LRU" max-entries="10000"/>
                              <expiration max-idle="100000"/>
                          </local-cache>
                          <invalidation-cache name="entity" mode="SYNC" start="EAGER" >
                              <transaction mode="NON_XA"/>
                              <eviction strategy="LRU" max-entries="10000"/>
                              <expiration max-idle="100000"/>
                          </invalidation-cache>
      {code:xml}
      

       
      

       
      

      but that gives me
      

       
      

       
      

       
      

       Caused by: java.lang.NullPointerException
      at org.hibernate.cache.infinispan.InfinispanRegionFactory.getCache(InfinispanRegionFactory.java:445)
                at org.hibernate.cache.infinispan.InfinispanRegionFactory.buildEntityRegion(InfinispanRegionFactory.java:198)
       

       

       

      My persistence.xml looks like this

       

       

      {code:xml}  <persistence-unit name="my-pu" transaction-type="JTA">
                          <provider>org.hibernate.ejb.HibernatePersistence</provider>
                          <jta-data-source>java:jboss/datasources/mydatasrc</jta-data-source>
                          <shared-cache-mode>ENABLE_SELECTIVE</shared-cache-mode>
                    <properties>
                          <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect" />
                          <property name="hibernate.hbm2ddl.auto" value="update"/>
                          <property name="hibernate.cache.use_second_level_cache" value="true" />
                    <property name="hibernate.cache.use_query_cache" value="true" />     
                              <property name="hibernate.cache.region.factory_class" value="org.hibernate.cache.infinispan.JndiInfinispanRegionFactory"/>
                              <property name="hibernate.cache.infinispan.cachemanager" value="java:CacheManager/entity"/>
                              <property name="hibernate.cache.region.jbc2.query.localonly" value="true" /> 
                          </properties>
                </persistence-unit>      {code:xml}

       

       

       

      SO!... Is my only issue I need to find teh right way to add teh cache to JNDI or I have I bigger configuration issues? Any tips/help very much appreciated.

       

      Best regards
