Question

我正在使用在TomEE上运行的Java编写的WebApp。作为持久层，我使用Hibernate。已配置Persistence.xml，实体管理器由TomEE在@PersistenceContext(name = "persistentUnitJndi", unitName = "docTracingPU") EJB中使用@Stateless(name = "utenteFacade", mappedName = IUtente.MAPPED_NAME)实例化。

它似乎工作正常，但所有查询都返回一个空结果（空列表）。 DB是PostrgeSQL，我试过8.4和9.2但结果总是一样。

我在postrges（postgresql.conf）上登录，我只读Could not receive data from client: Unknown winsock error 10061。

我尝试关闭防病毒软件和/或防火墙....没有任何变化。

怎么办？

编辑：

我在Win8.1机器上尝试过相同的项目。我得到user lacks privilege or object not found

我找到了：

hibernate.cfg.xml不是neede
仅需要persistence.xml和tomee.xml

我举了我的例子：

<persistence version="1.0"

    <jta-data-source>java:comp/env/jdbc/docTracing</jta-data-source>
    <non-jta-data-source>java:comp/env/jdbc/docTracing</non-jta-data-source>

    <class>com.emaborsa.doctracing.core.persistentobject.UtentePO</class>

        <property name="hibernate.hbm2ddl.auto" value="validate" />
         <property name="hibernate.transaction.flush_before_completion" value="true"/>

        <property name="hibernate.transaction.manager_lookup_class" value="org.apache.openejb.hibernate.TransactionManagerLookup" />
         <property name="hibernate.transaction.flush_before_completion" value="true"/>
         <property name="hibernate.transaction.auto_close_session" value="true"/>

        <!-- Print SQL to stdout. -->
        <property name="hibernate.show_sql" value="true" />
        <property name="hibernate.format_sql" value="true" />
    </properties>
</persistence-unit>
