CXF的server端可以調用外部的webserver嗎?
想在server端調用外部的wevserver如 .net或axis2等server 回傳值
在cxf server端進行運算，不知是否可行?
有嘗試調用，卻出現錯誤

Java code

import javax.jws.WebService;   
  
import org.apache.cxf.endpoint.Client;  
import org.apache.cxf.jaxws.endpoint.dynamic.JaxWsDynamicClientFactory;  
  
class WebServiceClientHelper {  
    public static String callService(String wsUrl, String method, Object... arg) {  
        JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory.newInstance();  
        Client client = dcf.createClient(wsUrl);  
        Object[] res = null;  
        try {  
            res = client.invoke(method, arg);  
        } catch (Exception e) {  
            e.printStackTrace();  
        }  
        return (String) res[0];  
    }  
}  
  
@WebService  
public class CXFtestImpl implements CXFtest {  
  
    @Override  
    public String sayCXF(String name) {  
        // TODO Auto-generated method stub  
          
        String str = WebServiceClientHelper.callService("http://localhost:8080/axis2/services/Version?wsdl", "getVersion", "");  
        //System.out.println(str);  
          
        return "Hello " + name;   
    }  
} 

調用時出現的錯誤如下：
