wsgen限制:要避免什么构造

wsgen soap web-services java

Kaleb Pederson · 技术社区 · 16 年前

我正在使用JAX-WS(jsr224)@webservice和@WebMethod注释创建一个web服务。虽然我发现 the specification

到目前为止,我在使用JDK 6提供的JAX-WS 2.1.6时偶然发现:

不能将接口用作参数、返回值或对象成员
所有类都必须提供无参数的默认构造函数

wsgen的局限性是什么?我应该避免哪些构造?

我还偶然发现了一些奇怪的错误,所有这些错误看起来都与以下类似,而且可能是一个bug:

看看这是否有助于解决奇怪的错误(我用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/
