applet作为UI页面，数据处理层使用EJB3，这个方案是否可行？

[SW13968086129]

applet的init函数如下：
public void init() {
super.init()
try {
String jndiPath = "ManageIndexDAOBean/remote";
Properties props = new Properties();

/* JBOSS 服务器 */
props.setProperty("java.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory");
props.setProperty("java.naming.provider.url", "localhost:1099");
props.setProperty("java.naming.factory.url.pkgs", "org.jboss.naming:org.jnp.interfaces");
InitialContext ctx = new InitialContext(props);
ManageIndexDAO dao = (ManageIndexDAO)ctx.lookup(jndiPath);
if (dao != null) {
}
} catch (NamingException e) {
e.printStackTrace();
}
}

调用Applet的html内容如下：
<applet codebase="."
code="cn.hz.epower.applet.ManageIndexApplet.class"
name="ManageIndexApplet"
archive="Client/jbossall-client.jar,
Client/jboss-ejb3-client.jar,
Client/jboss-aop-jdk50-client.jar,
Client/jboss-aspect-jdk50-client.jar,
Client/PlanStatManageLocal.jar"
width="520"
height="240">
</applet>
</body>

RMI似乎可以实现的

最后说明：
1、EJB3类没有问题，在客户机器上测试通过。
2、部署EJB3的服务器采用jboss-4.2.1.GA

苦恼了我好多天了，不知道有没有高手能帮我解决一下，或者提供给我一个思路，对回贴的人不胜感激

不用applet不行吗？ 直接用jsp或者html

[jeff2033333]

applet是在用户的jre上跑的，访问EJB组件只能用远程方式，性能上恐怕会比jsp/servlet差很多。
