Java SOAP 客户端抛出异常 "Call to a member function setValue() on a non-object"

Question

我使用 Eclipse 的内置 Web 服务客户端创建器创建了一个 Web 服务客户端(我相信它使用 Apache Axis 生成代码？)，但我遇到了一个我似乎无法弄清楚的错误。以下是异常情况:

Exception in thread "main" AxisFault
 faultCode: {http://schemas.xmlsoap.org/soap/envelope/}Server
 faultSubcode: 
 faultString: Call to a member function setValue() on a non-object

我正在使用OppsPlace提供的API (一个招聘网站)，具体来说，我使用了这个 WSDL为他们的测试环境构建客户端。

基本上，我创建一个 Job 对象和一个 Contact 对象(从 WSDL 生成的类)，它们与我的唯一 ID 一起传递到服务中。无论我尝试在代码中进行什么更改，它都会因同样的异常而爆炸。

正如我们所看到的，异常发生在 Apache 代码的深处，而我一生都无法弄清楚为什么。有什么想法/想法吗？

它提到了“成员函数”，而Java官方没有函数，只有方法。该错误消息看起来像 PHP“调用非对象上的成员函数”。 OppsPlace API 用 PHP 实现可能并非巧合。

恭喜，您在调用的 API 中遇到了错误。
