Jbuider2006 作EJB使用Entity Bean时,数据源连接出问题
使用jbuilder 按照建工程,建Ejb module,建CMP及web module,使用默认值,不改变设置和方法,不增加任何代码,完全是自动生成,可是调试时,提示说数据源未连接...(见messenge,附后),但是我用data source时,检测并载入了数据库,这是什么原因呢?请大家帮忙!!!!

操作步骤：
数据库驱动：sun.jdbc.odbc.JdbcOdbcDriver； url为jdbc:odbc:jspTest
1. 在JBuilder2006中配置Jboss4.x+后,新建一个项目，名称为EjbTest，目录为EjbTest，点击Finish完成。
2. 在左边的导航中，选中EjbTest项目，点击鼠标右键，选择属性。在EjbTest属性对话框中，选择Server标签，选择Single server for all services in project，然后在下拉列表中选择Jboss4.x＋，确定。
3. 在JBuilder的菜单中选择File | New，在Object Gallery对话框中选中Enterprise标签，并选中EJB Module，确认。
4. 在EJB Module Wizard对话框中，一切默认，确定。数据源设定如下：
5. 创建EJB Module后，创建CMP2.x Entity Bean
6. 创建会话代理，参数选择默认，其中创建Webmodule
7. 完成，编译，调试
8. 启动Jboss，运行客户端
