안녕하세요. 나는 자바와 GWT를 처음 사용한다. Filenet에서 GWT를 사용하여 RPC 호출을 사용하는 RPC 호출이 있습니다.들어오는 RPC 호출을 디스패치하는 동안 예외가 발생했습니다.
remoteservices를 확장하는 FcInterface.java에는 세 가지 메소드가 있습니다. 인터페이스의 2 메서드는 serber에서 값을 client에 반환하는 작업을 잘 수행하고 있습니다. 하지만 세 번째 방법에는 문제가 있습니다. 서버 측에서 클라이언트 측으로 값을 반환 할 수 없습니다.
스택 추적 코드를 첨부하십시오. 클래스에 대한
는Code:
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;
}
}
코드 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){
this.FolderName=Foldername;
}
public FilenetFolderImpl(String name, String id, String baseTypeId,
GregorianCalendar lastModificationDate, String lastModifiedBy) {
// TODO Auto-generated constructor stub
this.FolderName = name;
this.FolderId = id;
this.FolderClass = baseTypeId;
this.FolderModifiedBy = lastModifiedBy;
this.FolderModifiedOn = lastModificationDate;
}
public FilenetFolderImpl() {
// TODO Auto-generated constructor stub
}
public String getFolderName() {
return FolderName;
}
public void setFolderName(String FolderName) {
this.FolderName=FolderName;
}
public String getFolderId() {
return FolderId;
}
public void setFolderId(String FolderId) {
this.FolderId=FolderId;
}
public String getFolderClass() {
return FolderClass;
}
public void setFolderClass(String FolderClass){
this.FolderClass=FolderClass;
}
public String getFolderModifiedBy() {
return FolderModifiedBy;
}
public void setFolderModifiedBy(String FolderModifiedBy) {
this.FolderModifiedBy=FolderModifiedBy;
}
public GregorianCalendar getFolderModifiedOn() {
return FolderModifiedOn;
}
public void setFolderModifiedOn(GregorianCalendar gregorianCalendar) {
this.FolderModifiedOn=gregorianCalendar;
}
protected Map<String, String> addFolder(){
Map<String, String> newFolderProperties = new HashMap<String, String>();
newFolderProperties.put(PropertyIds.OBJECT_TYPE_ID,"cmis:folder");
newFolderProperties.put(PropertyIds.NAME,FolderName);
return newFolderProperties;
}
}

가 직렬화에 문제가 아니면 내가 유형 인 ContentOfRootFolder를 사용 FilenetFolderImpl의 obect을 보내 질수 Map<String, Object> ContentOfRootFolder = new HashMap<String, Object>(); 어쨌든 FilenetFolderImpl의 값을 반환해야합니다.
이 문제를 해결하는 데 도움을주십시오. 감사합니다. .
