我正在关注我从 The Server Site 网站下载的 MasteringEJB4thEdition 书。
有一个 HelloBean 的简单示例，它与 GlassFish V3 应用服务器完美配合。由于 JNDI 名称查找，部署在 JBOSS 上的相同示例失败。
如果我们不提供任何规则，是否有任何规则如何决定 JBOSS 中的 JNDI 查找名称？我在谷歌搜索时发现它是“ear-file-name/Bean-class-name/remote”，但它对我不起作用。
这里是豆
1. package com.hardik.stateless;
2. import javax.ejb.Stateless;
3. import javax.ejb.Remote
4.
5.
6.
7.
8. @Stateless
9. @Remote(Hello.class)
10. public class HelloBean implements Hello {
11.
12. public String hello() {
13. System.out.println("hello()");
14. return "Hello, World!";
15. }
16.
17. }
这是我正在使用的客户端：
1. package com.hardik.stateless;
2.
3. import javax.naming.Context;
4. import javax.naming.InitialContext;
5.
6.
7. /**
8. * This is an example of client code which invokes
9. * methods on a simple, remote stateless session bean
10. * @author hardik
11. *
12. */
13. public class HelloClient {
14.
15. public static void main(String[] args) throws Exception {
16.
17. Context ctx = new InitialContext();
18. // works for Glassfish
19. //Hello hello = (Hello) ctx.lookup("com.hardik.stateless.Hello");
20. // doesn't work for JBOSS
21. Hello hello = (Hello) ctx.lookup("hello-bean/HelloBean/remote");
22.
23. System.out.println(hello.hello());
24. }
25.
26. }
这是我在执行客户端时遇到的错误
