JBoss AS 7.1.1的Persistence.xml

Question

我有一个客户端和服务器设置与JBoss AS 7.1.1一起运行,我有一个关于我的persistence.xml的问题.目前它看起来像这样:

<persistence>
    <persistence-unit name="GrahamsProj">
        <provider>org.hibernate.ejb.HibernatePersistence</provider>
        <jta-data-source>java:jboss/datasources/WorkCenterDS</jta-data-source>
        <properties>
            <property name="hibernate.dialect" value="org.hibernate.dialect.HSQLDialect"/>
            <property name="hibernate.hbm2ddl.auto" value="create-drop"/>
            <property name="hibernate.connection.driver_class" value="oracle.jdbc.OracleDriver"/>
        </properties>
    </persistence-unit>
</persistence>

我的服务器的META-INF文件夹中有persistence.xml.我必须缺少一些属性,因为当我尝试查询我连接的数据库时,我收到此错误.

11:35:07,840 ERROR [org.jboss.ejb3.invocation] (EJB default - 1) JBAS014134: 
EJB Invocation failed on component GrahamsProjBean for method public abstract 
void grahamsprojserver.session.interfaces.GrahamsProjBeanRemote.test(): javax.ejb.EJB
Exception: java.lang.IllegalArgumentException: org.hibernate.hql.internal.ast.QuerySyntaxException: 
Schemas is not mapped [FROM Schemas s]

有什么我想念的吗？

您需要在persistence.xml中包含所有模型类.例:

<persistence>
    <persistence-unit name="GrahamsProj">
        <provider>org.hibernate.ejb.HibernatePersistence</provider>
        <jta-data-source>java:jboss/datasources/WorkCenterDS</jta-data-source>
        <class>your.class.model.Example</class>
        <properties>
            <property name="hibernate.dialect" value="org.hibernate.dialect.HSQLDialect"/>
            <property name="hibernate.hbm2ddl.auto" value="create-drop"/>
            <property name="hibernate.connection.driver_class" value="oracle.jdbc.OracleDriver"/>
        </properties>
    </persistence-unit>
</persistence>
