JNDI Sample

    //载入jboss的SPI相关参数,包括初始上下文工厂，服务URL，等等
    env.load(new FileInputStream("jbossJndi.properties"));

    //通过JNDI api 初始化上下文

上述示例程序在jboss服务器的jndi树上建立了几个上下文,并bind了几对象,
结果为：
-----------------------------
/sylilzy/sily
-----------------------------
/sylilzy/sily/b:I am sily b!
/sylilzy/sily/a:I am sily a!
/sylilzy/sily/g1:this is g
-----------------------------
