在Jboss服务器中配置的数据源JDNI名称由属性指定hibernate.connection.datasource。

基本hibernate.cfg.xml应如下所示：

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
        "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
        "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

<hibernate-configuration> 
    <session-factory>

        <!-- Database connection settings -->
        <property name="hibernate.connection.datasource">java:comp/env/jdbc/EmployeeDB</property>

        <!-- SQL dialect -->
        <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>

        <!-- Mapped annotated entity-->
        <mapping class="org.hibernate.tutorial.domain.Event"/>

    </session-factory> 
</hibernate-configuration>
