我第一次使用apache CXF。我试图根据CXF simple front end（Configuration notes）技术建立连接。我无法真正看到我做错了什么，但我得到一个奇怪的错误（见下文）。我也发布了这个问题到[email protected]，但我还没有收到答复。也许这里有人可以帮忙。Apache CXF（简单前端）中的问题：'已连接'
这里包装的服务bean是Spring/JPA服务，它不知道任何有关Web的内容，我想用简单的前端将它作为Web服务发布，而不必使用Jax-ws等进行注释。 （这在理论上是有效的）。下面是我的配置：
服务器：

在客户端，我注入了生成的服务到我的web应用程序（我我使用wicket，但这应该是无关紧要的），当我打电话给服务方法时，我得到了一个来自java.net.HttpURLConnection的IllegalStateException表示连接已经打开。这里的堆栈跟踪：

这种情况在第一时间拨打服务电话是由，那就是之前打开的唯一的URLConnection是在WSDL的。
我在网上搜索了类似的问题，但是我发现所有的问题都是使用已经修复的问题。我正尝试使用简单的前端，因为我的服务没有使用jax-ws注释进行注释，我想保留它。
有人可以帮忙吗？提前致谢。
