我使用Google GWT和RPC。在客户端是类SplitDatenhalter。这工作正常：Google GWT RPC Vector
Vector <SplitDatenhalter> vec = new Vector<SplitDatenhalter>();
vec.add(new SplitDatenhalter("a", "b", "c","D"));
vec.add(new SplitDatenhalter("ab", "bc", "dc","Dee"));
如何发送到服务器端？
更新
我在客户端类SplitDatenhalter。见下文，
public class SplitDatenhalter implements Serializable{
private static final long serialVersionUID = 1L;
String name ;
String vorname;
String nachname;
String email;
public SplitDatenhalter(String name, String vorname, String Nname, String Email) {
this.name = name;
this.vorname = vorname;
this.nachname = Nname;
this.email = Email;
}
public String getName() {
return name;
}
//others setter and getter Function
客户端侧具有MyService：
public interface MyService extends RemoteService
{
public void myVector(Vector<SplitDatenhalter> vec);
}
另一个接口：
public interface MyServiceAsync {
public void myVector(Vector <SplitDatenhalter> vec,
AsyncCallback <Void> callback);
}
这是服务器侧：
public void myVector(Vector <SplitDatenhalter> vec)
{
// TODO Auto-generated method stub
System.out.println("vector");
for (int i = 0; i < vec.size(); i++) {
this.name = vec.get(i).getName();
this.name = vec.get(i).getVorname();
this.name = vec.get(i).getNachname();
this.name = vec.get(i).getEmail();
}
}
此代码部分来自客户端：
Vector<SplitDatenhalter> vect = new Vector<SplitDatenhalter>(); // TODO Auto-generated method stub
MyServiceAsync svc = (MyServiceAsync) GWT.create(MyService.class);
ServiceDefTarget endpoint = (ServiceDefTarget) svc;
// endpoint.setServiceEntryPoint("/myService");
// define a handler for what to do when the service returns a result
@SuppressWarnings("rawtypes")
AsyncCallback callback = new AsyncCallback()
{
@Override
public void onFailure(Throwable caught) {
// TODO Auto-generated method stub
System.out.println("Fehler");
}
//@Override
public void onSuccess(Object result) {
// TODO Auto-generated method stub
System.out.println(result.toString());
}
};
this.vect.add(new SplitDatenhalter(this.name, Vname, Nname, Email)); //this a part from Function
我需要这部分代码
public static MyServiceAsync getService()
{
MyServiceAsync svc = (MyServiceAsync) GWT.create(MyService.class);
ServiceDefTarget endpoint = (ServiceDefTarget) svc;
endpoint.setServiceEntryPoint("/myService");
return svc;
}
最后一部分：执行此函数
@ SuppressWarnings("unchecked")
public void vectorExe()
{
System.out.println("vectorExe befor");
getService().myVector(this.vect, callback);
}
后，我从onFailure(Throwable caught)得到一个错误。我哪里做错了？
