MyWebService WebService = new MyWebService () ؛
ومع ذلك ، فإنه يموت ويلقي الخطأ التالي ، وهو غامض للغاية:

المحلول
من المرجح أن تكون هذه مشكلة في برنامج تحميل classload حيث يقوم متعددون بتحميل فئات API Jaxws. تتمثل فكرتي الرئيسية في التحقق من محولات الدرجة والحروب والمناطق المعتمدة ومثل أي من الجرار Jaxws-Api وتأكد من العثور عليها فقط في مكان واحد.
نصائح أخرى
لقد عملت حول مشكلة jboss classloader باستخدام الكود التالي:
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);
