我正在尝试像这样调用 jax ws 操作:
MyService myProxy = getProxy();
boolean gmFlagUpdated = false;
GmFlagUpdate gmFlagUpdate = new GmFlagUpdate();
gmFlagUpdate.setPoint("Point1");
gmFlagUpdate.setMyID("ID1");
gmFlagUpdate.setGMFlag("true");
try {
gmFlagUpdated = myProxy.setGMFlag(gmFlagUpdate);
log.info("IsgmFlagUpdated-->"+gmFlagUpdated);
} catch (OperationFaultException e) {
e.printStackTrace();
} catch (SystemFaultException e) {
e.printStackTrace();
}catch(Exception e){
e.printStackTrace();
}
问题是它给了我以下错误:
java.lang.NullPointerException
at $Proxy28.setGMFlag(Unknown Source)
at com.kunal.gm.MyServiceFacade.main(MyServiceFacade.java:84)
行 : 84 是gmFlagUpdated = myProxy.setGMFlag(gmFlagUpdate);
try 块内的这一行。
奇怪的是,我已经尝试了同一个 WS 的另一个操作,它给了我一个完美的响应。
我在这里做错了什么吗?还是因为我正在使用的 WSDL 最近可能已更新/更改?
编辑 :
getProxy() 实现:
public static MyService getProxy() {
URL url = null;
try {
URL baseUrl = com.kunal.gm.service.MyService_Service.class.getResource("/com/kunal/gm/");
url = new URL(baseUrl, "file:./MyWSDL.wsdl");
} catch (MalformedURLException malformedURLException) {
System.out.println(malformedURLException.toString());
}
QName serviceName = new QName("http://com.host.provider/deploy/service","MyService");
MyService_Service service = new MyService_Service(url, serviceName);
MyService myPort = service.getPort();
BindingProvider bp = (BindingProvider) myPort;
bp.getRequestContext().put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY,"https://endpoint.com.myWSDL");
bp.getRequestContext().put(BindingProvider.USERNAME_PROPERTY,"username");
bp.getRequestContext().put(BindingProvider.PASSWORD_PROPERTY,"password");
return myPort;
}
非常感谢任何建议/帮助。
