Java Web服务 java.lang.ClassCastException : org. apache.cxf.jaxws.ServiceImpl

Question

我正在使用 Maven、CXF 2.2.7、JBoss 4.2.3 和 JRE 1.5 已更新

我有一个 Web 服务，可以使用 URL myURL/myService?wsdl 在服务器上查看该服务

我正在尝试开发一个 Web 应用程序，通过在我的 bean 中调用它来 ping 该 Web 服务:

MyWebService webservice = new MyWebService();

但是，它死了并抛出以下错误，该错误非常模糊:

Answer 1

我使用以下代码解决了这个 JBoss 类加载器问题:

import javax.xml.ws.Service;
import javax.xml.ws.soap.SOAPFaultException;
import javax.xml.ws.spi.ServiceDelegate;
import org.apache.cxf.Bus;
import org.apache.cxf.BusFactory;
import org.apache.cxf.jaxws.ServiceImpl;

Bus bus = BusFactory.newInstance().createBus();
ServiceDelegate service = new ServiceImpl(bus, url, portName, null);
Dispatch<Source> dispatch = service.createDispatch(portName, Source.class, Service.Mode.MESSAGE);
