我有要保存在Postgres DB中的EJB3 Entity bean。我正在使用Glassfish 3 App服务器来部署EJB。

当我使用我的Web层调用EJB时​​,会调用DB调用,但Glassfish会抛出以下异常

  javax.enterprise.system.std.com.sun.enterprise.server.logging|_ThreadID=135;_ThreadName=Thread-1;|javax.persistence.PersistenceException: org.hibernate.exception.JDBCConnectionException: could not inspect JDBC autocommit mode

at org.hibernate.ejb.AbstractEntityManagerImpl.find(AbstractEntityManagerImpl.java:589)
at com.cricinfo.session.service.PlayerService.getPlayer(PlayerService.java:41)

的根本原因是

与Postgres DB的连接已启动,我可以使用pgAdmin工具查看数据。我可以在日志中看到正在执行的查询。从日志中我们可以看到Glassfish正在使用derby客户端来获取连接。

我需要在Glassfish中进行任何配置吗?

persistence.xml是:

<persistence-unit name="PlayerApp" transaction-type="RESOURCE_LOCAL">
    <provider>org.hibernate.ejb.HibernatePersistence</provider>
    <class>com.cricinfo.domain.Player</class>
    <properties>
         <property name="hibernate.connection.driver_class" value="org.postgresql.Driver" 
            /> <property name="hibernate.dialect" value="org.hibernate.dialect.PostgreSQLDialect" 
            /> <property name="hibernate.hbm2ddl.auto" value="update" /> <property name="hibernate.connection.url" 
            value="jdbc:postgresql://localhost:5432/PlayerAppDB" /> <property name="hibernate.show_sql" 
            value="true" /> <property name="hibernate.format_sql" value="true" /> <property 
            name="hibernate.connection.username" value="postgres" /> <property name="hibernate.connection.password" 
            value="postgres" /> 
    </properties>
</persistence-unit>

我可以使用直接使用EntityManagerFactory的独立类来持久化并获取数据。

编辑:解决方案

我更多地阅读了它,并意识到我在persitence.xml中犯了一个错误。现在persistence.xml看起来像这样:

<persistence-unit name="PlayerApp" transaction-type="JTA">
    <provider>org.hibernate.ejb.HibernatePersistence</provider>
     <jta-data-source>jdbc/DefaultDS</jta-data-source>
    <class>com.cricinfo.domain.Player</class>
</persistence-unit>

交易类型是 JTA ,并且使用了数据源而不是连接属性。

我还登录了Glassfish管理控制台,并从树CommonTasks-&gt;树中配置了JDBC连接池和JDBC资源。资源 - &gt; JDBC

我现在能够获得详细信息。
