Multiple EntityManagers
I've been trying now for sometime to get a second EntityManager to deploy successfully using EJB 3.0 and JBoss 4.0.3 SP1.
My second EntityManager references existing Entities and a second database. The pesistence.xml for my second EntityManager is as follows:
<?xml version="1.0" encoding="UTF-8"?> <entity-manager> <name>open4ejbempublished</name> <jta-data-source>java:/inmezzo2published</jta-data-source> <properties> <property name="hibernate.hbm2ddl.auto" value="create-drop"/> <property name="hibernate.show_sql" value="false" /> <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect" /> <property name="hibernate.cache.provider_class" value="org.jboss.ejb3.entity.TreeCacheProviderHook"/> <property name="hibernate.treecache.mbean.object_name" value="jboss.cache:service=EJB3EntityTreeCache"/> </properties> <class>com.inmezzo.entity.AuditService</class> <class>com.inmezzo.entity.DatabaseConnection</class> <class>com.inmezzo.entity.Deployment</class> <class>com.inmezzo.entity.DeploymentPolicy</class> <class>com.inmezzo.entity.Domain</class> <class>com.inmezzo.entity.Field</class> <class>com.inmezzo.entity.FieldFieldGetter</class> <class>com.inmezzo.entity.FieldGetter</class> <class>com.inmezzo.entity.Policy</class> <class>com.inmezzo.entity.PolicyGroup</class> <class>com.inmezzo.entity.SampleData</class> <class>com.inmezzo.entity.Service</class> <class>com.inmezzo.entity.ServiceNode</class> <class>com.inmezzo.entity.ServiceServiceNode</class> <class>com.inmezzo.entity.SQLGetter</class> <class>com.inmezzo.entity.URL</class> <class>com.inmezzo.entity.User</class> <class>com.inmezzo.entity.WebServiceService</class> <class>com.inmezzo.entity.XMLGetter</class> </entity-manager>
The datasource inmezzo2published does deploy successfully when the datasource xml file is copied to the JBoss deploy directory.
The second EntityManager is stored in a par file called entitiespublished.par. The entitiespublished.par file only contains the persistence.xml file as shown below.
<!-- Package the persistence module for publishing -->
<target name="package-published-par" depends="compile">
<jar jarfile="${build.dir}/jar/entitiespublished.par">
<metainf dir="dd/persistence">
<include name="persistencepublished.xml"/>
</metainf>
</jar>
</target>
The application.xml file is shown below. The entities.par file shown below contains all the entities.
<?xml version="1.0" encoding="UTF-8"?> <application version="1.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/application_1_4.xsd"> <display-name>Open4EJB</display-name> <module> <ejb>entities.par</ejb> </module> <module> <ejb>entitiespublished.par</ejb> </module> <module> <ejb>Open4EJB.jar</ejb> </module> <module> <ejb>business.ejb3</ejb> </module> </application>
The Second EntityManager is referenced as follows:
import java.util.List;
import javax.annotation.Resource;
import javax.annotation.security.RolesAllowed;
import javax.ejb.Remote;
import javax.ejb.SessionContext;
import javax.ejb.Stateless;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
import org.jboss.annotation.security.SecurityDomain;
import com.inmezzo.audit.AuditService;
import com.inmezzo.entity.Deployment;
import com.inmezzo.entity.Domain;
import com.inmezzo.remote.DeploymentDAO;
@Stateless
@Remote( { DeploymentDAO.class } )
@SecurityDomain( "open4ejb" )
public class DeploymentDAOBean implements DeploymentDAO
{
@Resource SessionContext ctx;
@PersistenceContext(unitName = "open4ejbem")
protected EntityManager em;
@PersistenceContext(unitName = "open4ejbempublished")
protected EntityManager em2;
...
The Deployment error is as follows:
