EJB3嵌入式：J2SE工程调用

自:http://hi.baidu.com/jt618/blog/item/e495164f69a47c33aec3ab2f.html

 

在JOBoss官网下载嵌入式开发包：

jboss-EJB-3.0_Embeddable_ALPHA_9

将jboss-EJB-3.0_Embeddable_ALPHA_9\bin\开发包导入到J2SE工程的Bin目录下

将jboss-EJB-3.0_Embeddable_ALPHA_9\ conf\开发包导入到J2SE工程的src目录下

将src目录引入数据源引用：META-INF\ persistence.xml
