Question

我正在寻找各地试图找出如何将无状态会话bean转换为JAX-WS Web服务（我使用的是WAS 7，Websphere Integration Developer，EJB 3）。不是Jax-RPC。我正式厌倦了与WID附带的向导搞乱。出于某种原因，它根本不会让我这样做...我尝试从Java bean创建一个JAX-WS Web服务，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......

是否有某个教程可以在不必使用向导的情况下向我提供创建此Webservice所需的知识？

Answer 1

从Java EE 5教程中试试A Web Service Example: helloservice - The Java EE 5 Tutorial。

我写了一个小样本应用程序。
