java - Websphere 7 上的 EJB @Stateless 和 @WebService

Question

我四处寻找，试图找出如何将无状态 session bean 转变为 JAX-WS 网络服务(我使用的是 WAS 7、Websphere Integration Developer、EJB 3)。不是 Jax-RPC。我正式厌倦了摆弄 WID 附带的向导。出于某种原因，它根本不会让我这样做......我已经尝试从 Java bean 创建一个 JAX-WS webservice，换句话说，我创建了一个 Java 类并在那个东西上运行向导，它创建了一个全新的项目...

是否有某个地方的教程可以告诉我创建此 Web 服务所需的知识，而无需使用向导？

Answer 1

从 Java EE 5 教程尝试 A Web Service Example: helloservice - The Java EE 5 Tutorial .
