我正在使用 JAX-WS (JSR 224) 的@WebService 和@WebMethod 注释创建一个网络服务。虽然我找到了the specification ,我找不到任何记录在案的我遇到的限制。
到目前为止,这是我使用 JDK 6 提供的 JAX-WS 2.1.6 时偶然发现的内容:
- 您不能将接口(interface)用作参数、返回值或对象成员
- 所有类都必须提供无参默认构造函数
wsgen 的局限性是什么?我应该避免哪些结构?
我也偶然发现了一些奇怪的错误,所有这些错误看起来都类似于以下内容,并且可能是一个错误:
Note: ap round: 1

最佳答案
看看这是否有助于解决奇怪的错误(我通过适当的类路径设置解决了与您类似的错误): http://eskatos.wordpress.com/2007/10/16/glassfish-hibernate-and-webservices-wsgen-classpath/
