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，可以通过使用 URL myURL/myService?wsdl 在服务器上看到它

我正在尝试开发一个 Web 应用程序，通过在我的 bean 中调用以下命令来 ping 该 Web 服务：

MyWebService webservice = new MyWebService();

然而，它死了并抛出以下错误，该错误非常模糊：

我希望有人以前见过这个异常并可以帮助我。

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);

Answer 2

这很可能是一个类加载器问题，其中多个类加载器正在加载 jaxws api 类。我的主要想法是检查任何 jaxws-api jar 的类加载器、战争和认可区域等，并确保它只在一个地方找到。
