java - 从简单的 Java 客户端调用 Web 服务

Question

在 Eclipse 中，我在客户端编写此代码，从 wsdl 文件生成...

TravelAssistServicesStub t = new TravelAssistServicesStub();
ConversionRateByCountry c = new ConversionRateByCountry();
c.setCountry("India");
c.setUser_Id("satya");
ConversionRateByCountryResponse ccy = t.conversionRateByCountry(c);

System.out.println("Conversion: " + ccy.get_return());

...我得到以下异常:

Answer 1

您缺少 apache httpcomponents jar。确保它在运行时位于您的类路径中。
