请教webservice的问题，我的错误在哪里？

Question

public class YakWebServiceClient {
    private static JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
    private static FileService client;    private void Config(){
     try{
     factory.setServiceClass(FileService.class);
                  //webserviceAddress这个变量是我从配置文件里取得值，也就是http地址。
     factory.setAddress(webserviceAddress);
     client = (FileService) factory.create();
    
                  <以下省略……>
     }catch(Exception ex){
     Log.singleton().error(LOG_PREFIX + "Config function is false!");
     Log.singleton().error(ex);
     }
  
    }    <以下省略……>
}
我在调用Config这个函数时，出现了exception，也就是在执行factory.create()这段代码时报错。错误如下：

还是这个错误，就是在factory.create()时候报的错误。
我公司有代理，是不是和这个有关系？
