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