自从我一直在做GWT以来，我一直需要做一些很快完成的小事情。我设置了一些东西，现在我有一个我需要的RPC，但它失败了。GWT - RPC序列化异常
RPC应该给我一个ArrayList，空缺位于＃projectname＃.client.model中。 调用在#projectname＃.client.model中进行。
我的服务的接口位于＃project＃name.client.Service中。
最后，当然的调用转到#projectname＃.server。
空缺实现了IsSerializable。我从运行我的RPC得到例外的是以下内容：
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();
}
}
我想我已经做了所有我需要做出空缺序列化，和一个ArrayList的空缺作为RPC的返回类型算作空闲为返回类型..对吗？我究竟做错了什么？
在此先感谢！
你确定你在'Vacancy'类中实现了'com.google.gwt.user.client.rpc.IsSerializable'吗？ – 2012-03-02 14:09:04
'import com.google.gwt.user.client.rpc.IsSerializable;' 'public class空缺实现IsSerializable {' 绝对。 – 2012-03-02 14:10:42
