Привет. Я новичок в Java и GWT.
У меня есть вызов RPC для получения некоторых значений из Filenet, я использую GWT, где я использую вызов RPC,
У меня есть 3 метода в FcInterface.java, который расширяет удаленные сервисы. 2 метода в интерфейсе работают нормально, возвращая значения клиенту от serber. Но есть проблема с третьим методом, я не могу вернуть значение со стороны сервера на сторону клиента.
Присоединение кода n стека трассировки.
Code:
public class FilenetCmisServiceImpl extends RemoteServiceServlet implements FcInterface {
...
...Some codes
public Map<String, Object> getContentOfRootFolder(String RepositoryId) {
Map<String, Object> ContentOfRootFolder = new HashMap<String, Object>();
ItemIterable<CmisObject> children = root.getChildren();
for (CmisObject o : children) {
FilenetFolderImpl folder= new FilenetFolderImpl();
folder.setFolderName(o.getName());
folder.setFolderId(o.getId());
folder.setFolderModifiedBy(o.getLastModifiedBy());
folder.setFolderClass(o.getBaseTypeId().toString());
folder.setFolderModifiedOn(o.getLastModificationDate());
System.
out.println("name : " + o.getName());
ContentOfRootFolder.put(o.getName(), folder);
}// every thing is fine till here
return ContentOfRootFolder;
}
}
Код для класса FilenetFolderImpl
public class FilenetFolderImpl {
private String FolderName;
private String FolderSize;
private String FolderModifiedBy;
private GregorianCalendar FolderModifiedOn;
Folder root;
private String FolderId;
private String FolderClass;
public FilenetFolderImpl( String Foldername){

Я думаю, что есть проблема с сериализацией, или я не могу отправить объект FilenetFolderImpl с использованием ContentOfRootFolder, который имеет тип
Map<String, Object> ContentOfRootFolder = new HashMap<String, Object>();
В любом случае мне нужно вернуть значения FilenetFolderImpl.
Пожалуйста, помогите мне решить эту проблему.
Благодарю.
