使用JaxWsDynamicClientFactory的动态客户端生成java.lang.IllegalArgumentException错误

Question

我是Web服务编程中的另一个noobie，他遇到一个未知错误：

我正在尝试使用JaxWsDynamicClientFactory来动态调用所请求的服务（该服务的地址及其参数是从文件中读取的，但这与此处无关）。

该问题是由JaxWsDynamicClientFactory的此标准初始化引起的。

JaxWsDynamicClientFactory dcf= JaxWsDynamicClientFactory.newInstance();

执行此行后，Karaf（Felix）返回以下错误：

实际上，我对以下执行没有任何问题（程序继续运行不会产生任何影响），但是我想从屏幕上删除此讨厌的错误堆栈。 我试图通过try-catch环境隐藏该错误，但是Karaf只是忽略了该错误（即，虽然会打印整个堆栈，但不会触发catch部分）。

您能帮我解决问题吗（或者至少可以帮助您理解为什么这条简单的代码会产生问题）？

一般来说。 代码是在Eclipse Kepler中创建的，并使用Maven 2构建，并在Karaf（felix）中执行。 这是pom文件中的依赖项：

Answer 1

如CXF网站所述 ！

请注意，通常，CXF仅支持WSI-BP服务。 如果尝试为使用WSI-BP之外功能的WSDL创建动态客户端，则CXF可能会引发异常。

这可能是您的问题。 使用SOAPUI之类的工具进行检查，是否右键单击绑定并选择：检查WSI符合性

Answer 2

当为符合WS-I的WSDL创建动态客户端时，我遇到了相同的异常java.lang.IllegalArgumentException。 我相信这里报告的问题：

使用JaxWsDynamicClientFactory时发生IllegalArgumentException

是原因。
