自從我一直在做GWT以來，我一直需要做一些很快完成的小事情。我設置了一些東西，現在我有一個我需要的RPC，但它失敗了。GWT - RPC序列化異常
RPC應該給我一個ArrayList，空缺位於＃projectname＃.client.model中。 調用在#projectname＃.client.model中進行。
我的服務的接口位於＃project＃name.client.Service中。
最後，當然的調用轉到#projectname＃.server。
空缺實現了IsSerializable。我從運行我的RPC得到例外的是以下內容：
Starting Jetty on port 8888
[WARN] Exception while dispatching incoming RPC call
com.google.gwt.user.client.rpc.SerializationException: Type 'firsteight.client.model.Vacancy' was not included in the set of types which can be serialized by this SerializationPolicy or its Class object could not be loaded.

我所做的RPC如下：
void getVacs() {
try {
homeService.getVacancies(new AsyncCallback<ArrayList<Vacancy>>() {
public void onFailure(Throwable caught)
{
RootPanel.get("grayblock").add(new HTML("Failed:" + caught.getMessage()));
}
public void onSuccess(ArrayList<Vacancy> result)
{
RootPanel.get("grayblock").add(new HTML(result.get(0).getTitle()));
}
});
} catch (IllegalArgumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
我想我已經做了所有我需要做出空缺序列化，和一個ArrayList的空缺作爲RPC的返回類型算作空閒爲返回類型..對嗎？我究竟做錯了什麼？
在此先感謝！
你確定你在'Vacancy'類中實現了'com.google.gwt.user.client.rpc.IsSerializable'嗎？ – 2012-03-02 14:09:04
'import com.google.gwt.user.client.rpc.IsSerializable;' 'public class空缺實現IsSerializable {' 絕對。 – 2012-03-02 14:10:42
