我试图实现EJB持久性，但我在将应用程序部署到JBoss时遇到问题。在我的应用程序有会话bean TeamMgr，它看起来像这样：在实现持久性时将EJB应用程序部署到JBoss
package ejb;
import javax.ejb.Local;
import javax.ejb.Remote;
import javax.ejb.Stateless;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
import domain.TeamBean;
@Stateless
@Local(ITeamMgrLocal.class)
@Remote(ITeamMgrRemote.class)
public class TeamMgr implements ITeamMgrLocal, ITeamMgrRemote {
@PersistenceContext(unitName="team_workouts") private EntityManager manager;
public TeamMgr() {
// TODO Auto-generated constructor stub
}
@Override
public void addMember(int tid, int ub) {
System.out.println("In TeamMgr.addMember()...");
System.out.println("New Member ID: " + ub);
System.out.println("Leaving TeamMgr.addMember()...");
}
@Override
public void createTeam(int m1, int m2, int m3, int m4, int m5, String tn) {
System.out.println("In TeamMgr.createTeam()...");
System.out.println("Persisting team name: " + tn);
TeamBean tb = new TeamBean(tn, m1, m2, m3, m4, m5);
manager.persist(tb);
System.out.println("Leaving TeamMgr.createTeam()...");
}
}
我的persistence.xml文件看起来是这样的：
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence
http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">
<persistence-unit name="team_workouts">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<jta-data-source>java:MySqlDS</jta-data-source>
</persistence-unit>
</persistence>
最后，我有一个mysql-ds.xml文件：
<?xml version="1.0" encoding="UTF-8"?>
<datasources>
<local-tx-datasource>
<jndi-name>MySqlDS</jndi-name>
<connection-url>jdbc:mysql://mysql-hostname:3306/team_workouts</connection-url>

<metadata>
<type-mapping>mySQL</type-mapping>

</datasources>
当我尝试运行我的JBoss服务器上的应用程序，我得到了Eclipse控制台以下错误消息：
