Question

我在Jboss 7服务器中配置了容器管理数据源（“myDataSource”）。数据源似乎正确部署（我从管理控制台检查）我构建并部署了Spring示例webflow-primefaces-showcase应用程序到jboss，该演示已部署并正常工作。我想在演示中使用jboss数据源，但我无法使用它。此时我没有任何可以访问数据库的支持代码，我只想正确配置数据源。

我为oracle驱动程序

添加了对pom.xml的依赖

<dependency>
<groupId>com.oracle</groupId>
<artifactId>ojdbc6</artifactId>
<version>11.1.0.7.0</version>
</dependency>

我创建了META-INF / persistence.xml

<persistence-unit name="myDataSource-emf" transaction-type="JTA">
        <provider>org.hibernate.ejb.HibernatePersistence</provider>
        <jta-data-source>java:/myDataSource</jta-data-source>
      <properties>
         <property name="hibernate.dialect" value="org.hibernate.dialect.OracleDialect"/>
         <property name="hibernate.hbm2ddl.auto" value="validate"/>
         <property name="hibernate.show_sql" value="true"/>
         <property name="hibernate.format_sql" value="true"/> 
         <property name="hibernate.use_sql_comments" value="true"/>
         <property name="hibernate.default_schema" value="schemaUserName"/>
      </properties>
   </persistence-unit>

将此添加到web.xml：

 <persistence-unit-ref>
  <persistence-unit-ref-name>persistence/myDataSource-emf</persistence-unit-ref-name>
  <persistence-unit-name>myDataSource-emf</persistence-unit-name>
 </persistence-unit-ref>

当我现在部署时，我得到：

    "JBAS014771: Services with missing/unavailable dependencies" => 
    "jboss.persistenceunit.\"webflow-primefaces-showcase-1.0.0-BUILD-SNAPSHOT.war#myDataSource-emf\
    "jboss.naming.context.java.myDataSourceMissing
[jboss.persistenceunit.\"webflow-primefaces-showcase-1.0.0-BUILD-SNAPSHOT.war#myDataSource-emf\
    "jboss.naming.context.java.myDataSource]"]}

某处我必须添加jndi参考：

<jee:jndi-lookup id="entityManager" jndi-name="java:comp/env/persistence/myDataSource-emf" 
            expected-type="javax.persistence.EntityManager"/>

但我不知道在哪里。我是否需要创建ApplicationContext.xml？我可以把它放在rootContext.xml中吗？

如何让这两个人在一起玩得很好？

我的配置：

JBoss 7.1
Spring 3.1.2
Spring Web Flow 2.3.1

问题出在persistence.xml中我更改了这一行：

<jta-data-source>java:/myDataSource</jta-data-source>

为：

<jta-data-source>java:jboss/datasources/myDataSource</jta-data-source>

我把jndi查找放在servlet-context.xml中：

<jee:jndi-lookup id="entityManagerFactory" jndi-name="java:comp/env/persistence/myDataSource-emf" 
            expected-type="javax.persistence.EntityManagerFactory"/>

编辑架构引用以添加jndi标记：
