需要帮助将简单WS WebApp部署到ServiceMix

所以，我正在尝试将一个简单的Web Service Web应用程序部署到ServiceMix中。

SMX版本：5.4.0， Java版本：1.7.0_75

代码位于： https://github.com/yngwietiger/HelloWebService.git

我的应用包含2个servlet：HelloWebService（公开简单的Web服务）和MyServlet（非常基本的servlet）

我执行 mvn clean install 来构建war / bundle。

如果我运行 mvn tomcat：运行，它可以正常工作，我可以点击两个servlet。

e.g。 http://localhost:8080/HelloWebService/myservlet

和

http://localhost:8080/HelloWebService/helloWebService?wsdl

但是当我部署到SMX时，我收到以下错误：

所有代码都在顶部的GITHUB链接，如果有人想尝试的话。

如果我注释掉了WS servlet和listener，我可以在SMX中部署并点击简单的servlet（MyServlet）。但我无法让WS servlet工作。

任何想法/想法？

我认为这很容易，但这真的很痛苦。

我怀疑这是我的maven-bundle-plugin配置，但我真的不知道。

非常感谢任何帮助。

感谢。

来自太阳的普通jax ws在OSGi中不能很好地工作。您应该尝试使用Apache CXF。
