需要帮助将简单 WS WebApp 部署到 ServiceMix答案

【问题标题】：Need Help Deploying Simple WS WebApp into ServiceMix需要帮助将简单 WS WebApp 部署到 ServiceMix

【问题描述】：

所以，我正在尝试将一个简单的 Web Service webapp 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

我的应用程序包含 2 个 servlet：HelloWebService（公开一个简单的 Web 服务）和 MyServlet（非常基本的 servlet）

我执行 mvn clean install 来构建战争/捆绑包。

如果我运行 mvn tomcat:run，它可以正常工作，我可以同时访问两个 servlet。

例如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 链接中，如果有人想尝试。

如果我注释掉 WS servlet 和侦听器，我可以在 SMX 中部署并点击简单的 servlet (MyServlet)。但我就是无法让 WS servlet 工作。

有什么想法/想法吗？

我认为这很容易，但它真的很痛苦。

我怀疑这与我的 maven-bundle-plugin 配置有关，但我真的不知道。

任何帮助将不胜感激。

谢谢。

【问题讨论】：

嗯，解决了。只需要更新版本的 jaxws-rt.jar。

标签： java osgi jax-ws apache-servicemix

【解决方案1】：

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

见： Karaf Tutorial Part 4 - CXF Services in OSGi

【讨论】：

你知道，我刚刚开始怀疑这一点。我实际上认为我做了一个没有问题的示例 CXF 服务。我会查看您的链接并尝试一下。感谢您的回复！
事实证明，我只需要更新版本的 jaxws-rt.jar（例如 2.2.8 或 2.2.10）。希望我早点想到这一点。但它在 Tomcat 中工作的事实让我怀疑它是另外一回事。但是，我也确实让它与 CXF 一起使用。再次感谢。
