[jboss-dev-forums] [Design of EJB 3.0] - JPA deployers in jboss-ejb3-embedded

[jaikiran]

jboss-ejb3-embedded uses its own copy of jpa-deployers-beans.xml:


  | <?xml version="1.0" encoding="UTF-8"?>
  | <deployment xmlns="urn:jboss:bean-deployer:2.0">
  |    <bean name="DataSourceDependencyResolver" class="org.jboss.ejb3.embedded.resolvers.EmbeddedDataSourceDependencyResolver"/>
  |    
  |    <bean name="JavaEEModuleInformer" class="org.jboss.ejb3.embedded.javaee.SimpleJavaEEModuleInformer"/>
  |    
  |    <bean name="PersistenceUnitDependencyResolver" class="org.jboss.jpa.resolvers.DefaultPersistenceUnitDependencyResolver"/>
  |    
  |    <bean name="PersistenceParsingDeployer" class="org.jboss.jpa.deployers.PersistenceParsingDeployer"/>
  | 
  |    <bean name="PersistenceDeployer" class="org.jboss.jpa.deployers.PersistenceDeployer"/>
  |    <bean name="PersistenceUnitDeployer" class="org.jboss.jpa.deployers.PersistenceUnitDeployer">
  |       <property name="defaultPersistenceProperties">
  |          <map keyClass="java.lang.String" valueClass="java.lang.String">
  |             <entry>
  |                <key>hibernate.transaction.manager_lookup_class</key>
  |                <value>org.hibernate.transaction.JBossTransactionManagerLookup</value>
  |             </entry>
  |          </map>
  |       </property>
  |    </bean>
  | </deployment>

 While working on https://jira.jboss.org/jira/browse/EJBTHREE-1716 i had to upgrade the version of jboss-ejb3-core to 1.0.0 in the pom.xml dependency of embedded. This version of ejb3-core expects the PersistenceUnitDependencyResolver to have a search strategy and has various different impls. The ejb3-core by default uses:

  | <bean name="PersistenceUnitDependencyResolver" class="org.jboss.jpa.resolvers.DynamicPersistenceUnitDependencyResolver"/>

Which one do we want to use in the ejb3-embedded? Right now i have let it remain at 
DefaultPersistenceUnitDependencyResolver with a SpecCompliantSearchStrategy:

   <bean name="SpecCompliantSearchStrategy" class="org.jboss.jpa.resolvers.strategy.SpecCompliantSearchStrategy"/>
  |    
  |    <!-- DefaultPersistenceUnitDependencyResolver for spec compliant resolving. Uses SpecCompliantSearchStrategy-->
  |    <bean name="PersistenceUnitDependencyResolver" class="org.jboss.jpa.resolvers.DefaultPersistenceUnitDependencyResolver"/>
  | 

Is this OK? Or should ejb3-embedded too use the dynamic resolver?
