当我从我的web应用程序执行按钮时，我有以下错误:

我认为这个问题是由于无法访问EntityManagerFactory而产生的。persistence.xml是下一个:
<persistence 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_2_0.xsd"
version="2.0">
<persistence-unit name="gestionalumnos" transaction-type="JTA">
<jta-data-source>java:jboss/datasources/NotaneitorDS</jta-data-source>
<properties>
<property name="hibernate.dialect" value="org.hibernate.dialect.HSQLDialect"/>
<property name="jboss.entity.manager.factory.jndi.name" value="java:/JpaFactory"/>
</properties>
</persistence-unit>
</persistence>
负责获取EntityManager的类是Jpa.java:
package impl.sdi.persistence;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;
import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
public class Jpa {
private static EntityManagerFactory emf = null;
private static ThreadLocal<EntityManager> emThread =
new ThreadLocal<EntityManager>();
public static EntityManager createEntityManager() {
EntityManager entityManager = getEmf().createEntityManager();
emThread.set(entityManager);
return entityManager;
}
public static EntityManager getManager() {
return emThread.get();
}
public static EntityManagerFactory getEmf() {
if (emf == null){
emf = jndiFind("java:/JpaFactory");
}
return emf;
}
private static EntityManagerFactory jndiFind(String name) {
Context ctx;
try {
ctx = new InitialContext();
return (EntityManagerFactory) ctx.lookup(name);
} catch (NamingException e) {
throw new RuntimeException(e);
}
}
}
我想知道我是否做得很好，或者相反，我必须修复一些代码行。
由于将META-INF(包含persistence.xml)放在错误的目录(/WebContent)中而导致的错误。
