如何在WildFly中将DataSource资源引用名称映射到EJB 2.x中的JNDI名称？

Question

如何在WildFly中将DataSource资源引用名称映射到EJB中的JNDI名称？

我知道在JBoss 4.2.3中，它在jboss.xml中完成，但它在WildFly中不起作用。

这里是我的测试：

我与Java 1.7，XDoclet的1.2.3，WildFly 8.2.1.Final，动态Web模块2.5，EJB 2.1在Eclipse月神工作。

在WildFly中，我有一个名为SchedulerDS的数据源，其JNDI名称为java:jboss/datasources/SchedulerDS。它使用jTDS JDBC驱动程序并连接到MS SQL Server 2008 R2数据库。

在Eclipse中，我创建这些项目：一个名为Z01_EAR

1. 的企业应用程序项目。
2. 一个名为Z01_WAR的动态Web项目。
3. 一个名为Z01_EJB的EJB项目。
4. 名为Z01_EJBClient的EJB客户端项目。

在Z01_EJB项目中，我创建了一个名为SLS01的XDoclet无状态会话Bean（EJB 2.1）。其中我定义了名为jdbc/chumbo的DataSource资源参考。我将其映射定义为JNDI名称java:jboss/datasources/SchedulerDS。

这是ejb-jar.xml：

<?xml version="1.0" encoding="UTF-8"?> 
<ejb-jar id="ejb-jar_1" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/ejb-jar_2_1.xsd" version="2.1">

    <assembly-descriptor id="AssemblyDescriptor_1"> 
    </assembly-descriptor> 
    <ejb-client-jar>Z01_EJBClient.jar</ejb-client-jar> 
</ejb-jar> 

这是jboss.xml：

<?xml version="1.0" encoding="UTF-8"?> 
<!DOCTYPE jboss PUBLIC "-//JBoss//DTD JBOSS 4.0//EN" "http://www.jboss.org/j2ee/dtd/jboss_4_0.dtd">

    </enterprise-beans> 
    <assembly-descriptor> 
    </assembly-descriptor> 
    <resource-managers> 
    </resource-managers> 
</jboss> 

在EJB我写测试

public void testRetrieve() { 

    String dataSourceLookupString = null; 
    InitialContext initialContext = null; 
    DataSource dataSource = null;  
    Connection connection = null; 
    String sql = null; 
    Statement statement = null; 
    ResultSet resultSet = null; 
    long employeeId = -1; 


    try { 
     dataSourceLookupString = "java:comp/env/jdbc/chumbo";   
     initialContext = new InitialContext(); 
     dataSource = (DataSource) initialContext.lookup(dataSourceLookupString); 
     connection = dataSource.getConnection(); 
     sql = "select top 1 employee_id from employee"; 
     statement = connection.createStatement();   
     resultSet = statement.executeQuery(sql);    
     if (resultSet != null && resultSet.next()) { 
      employeeId = resultSet.getLong(1); 
      System.out.println("testRetrieve(): employeeId=" + employeeId); 
     }   
    } catch (NamingException e) { 
     e.printStackTrace();    
    } catch (SQLException e) { 
     e.printStackTrace(); 
    } finally { 
     try { 
      if (resultSet != null) { 
       resultSet.close(); 
      } 
     } catch (SQLException e) { 
      e.printStackTrace(); 
     } 

     try { 
      if (statement != null) { 
       statement.close(); 
      } 
     } catch (SQLException e) { 
      e.printStackTrace(); 
     } 

     try { 
      if (connection != null) { 
       connection.close(); 
      } 
     } catch (SQLException e) { 
      e.printStackTrace();     
     } 
    }  
} 

它没有工作的方法和我此错误：

现在我改变我的代码查找直接JNDI名称：

dataSourceLookupString = "java:jboss/datasources/SchedulerDS"; 

和它的工作完美。所以这意味着jboss.xml不适用于我的情况。在这种情况下，如何将DataSource资源引用名称映射到JNDI名称？

弄清楚，而不是jboss.xml我必须使用jboss-ejb3.xml为WildFly。
