我在创建 Java 客户端并将其连接到正在运行的 Web 服务时遇到问题。
我使用以下代码:
Service myService = null;
URL wsdlLocation = new URL("http://myservice?wsdl");
QName serviceName = new QName(wsdlLocation, "MyService");
Service myService = new Service(wsdlLocation, serviceName);
其中 Service 类是使用以下命令创建的:
wsimport -d gen -keep http://myservice?wsdl
我也尝试过使用 Apache cxf 2.4 的 wsdl2java 生成的客户端,但得到了相同的结果。
(我只为这篇文章更改了 WSDL 位置和服务类名称,在我使用原始代码的代码中。)
但是,当我调用部署在应用服务器上的 Web 服务时,使用 new Service() 命令创建服务时出现异常。但是:我已经使用 SOAP UI 测试了 wsdl 位置,它运行良好。另外,我使用 Soap UI 创建了一个模拟服务,我的 Java 客户端可以连接到它,调用它并返回结果。当我想调用在应用服务器上运行的 Web 服务时,就会出现问题。
