Question

我们正在将服务器从Jboss 5.1升级到Jboss 7.1 Final。但并非所有服务器都会立即转向新技术。

我正在升级Hibernate 4.0和Jboss 7.1上的第一台服务器。但是无法通过JNDI连接到位于Other Jboss Server（5.1）上的Datasource。

数据源（* -ds.xml）

<?xml version="1.0" encoding="UTF-8"?>
<datasources>
  <local-tx-datasource>
    <jndi-name>jdbc/wc-mysql</jndi-name>

    <connection-url>jdbc:mysql://XXX:3306/wellclub</connection-url>
    <driver-class>com.mysql.jdbc.Driver</driver-class>
    <user-name>myclub</user-name>
    <password>myclub</password>

    <exception-sorter-class-name>
          org.jboss.resource.adapter.jdbc.vendor.MySQLExceptionSorter
    </exception-sorter-class-name>

    <!-- The minimum connections in a pool/sub-pool. 
         Pools are lazily constructed on first use -->
    <min-pool-size>50</min-pool-size>
    <!-- The maximum connections in a pool/sub-pool -->
    <max-pool-size>200</max-pool-size>
    <!-- setting java context as Global so outsider can also use it. -->
    <use-java-context>false</use-java-context>
    <metadata>
       <type-mapping>mySQL</type-mapping>
    </metadata>
  </local-tx-datasource>
</datasources>

的hibernate.cfg.xml

<hibernate-configuration>
    <session-factory>
        <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>

        <property name="hibernate.connection.datasource">jdbc/wc-mysql</property>
        <property name="hibernate.jndi.url">jnp://jndi.wellclub.me:1099</property>
        <property name="hibernate.transaction.factory_class">org.hibernate.transaction.JTATransactionFactory</property>
        <property name="hibernate.jta.UserTransaction">UserTransaction</property>

        <property name="hibernate.show_sql">true</property>
        <property name="hibernate.current_session_context_class">jta</property>
        <property name="hibernate.transaction.manager_lookup_class">org.hibernate.transaction.JBossTransactionManagerLookup</property>
    </session-factory>
</hibernate-configuration>

在Hibernate Utility类中，我将SessionFactory作为

启动

Configuration configuration = new Configuration().configure();

// Add all the Annotated classes here...

ServiceRegistryBuilder builder = new ServiceRegistryBuilder();
builder.applySettings(configuration.getProperties());
serviceRegistry = builder.buildServiceRegistry();

sessionFactory = configuration.buildSessionFactory(serviceRegistry); <== Error

错误行

org.hibernate.service.jndi.JndiException: Unable to lookup JNDI name [jdbc/wc-mysql]

请告诉我我错过了什么。如果我以正确的方式这样做，我也想要一个指导。

Answer 1

我注意到可能是原因的两件事，

 1. <use-java-context>false</use-java-context>   - set it to true

 2. hibernate.jndi.class is different for Jboss 4 and 7 atleast.

那些事情可能会成功。

但我强烈建议你在JBoss 7上创建本地数据源。

Answer 2

可能你应该尝试查找像这样的数据源jndi名称

<property name="hibernate.connection.datasource">java:jboss/datasources/jdbc/wc-mysql</property>

在Jboss服务器管理控制台的配置文件选项卡下

连接器中的

- ＆gt; DataSources部分列出了数据源的JNDI名称

在升级到JBoss 7.1和Hibernate 4.0时无法连接到JNDI
