Java 获取Web服务端口时的NPE

我正在调用使用CXF Codegen插件为maven自动生成的WebService客户端：

return  edicionService.getEdicionWebPort().getEdicionWebOperation(detailOp(), id);

现在，当使用以下堆栈跟踪调用

getServicePort（）

时，这给了我一个NullPointerException：

java.lang.NullPointerException

有趣的是——它在我队友的几个环境中都有效，但在我的环境中却不行！我试着在我的环境中通过SOAPUI直接调用Web服务，结果它成功了。由于rt.jar类没有附加源代码，所以我无法准确地指出到底发生了什么。。。有什么我可能遗漏的吗？为什么它可以在某些计算机上工作，而不能在其他计算机上工作

---

顺便说一句，我们都在使用Liferay 6.1.1附带的JDK 1.6.0.20进行编译，这是一个迟来的答案，但希望能对其他人有所帮助。我也有同样的错误，这归结为编译和运行时之间jaxws rt库的不同版本：

• Maven构建中的JAXWS-RT 2.1生成SOAP客户端库
• JAXWS-RT 2.2.10在运行它的web容器（Weblogic）中

---

它通知我堆栈跟踪中使用了2.2.10版本。我将Maven构建更改为参考版本2.2.10，嘿，presto

代码中没有任何关于getServicePort的想法，它在GetDictionWebPort失败了吗？
