Need to access message received on a page

[Nitin Tomer]

Hi,

I have created a page on my facebook account, and need to access messages received on this page using restfb. I am able to retrieve the messages received on my account, but I am not able to retrieve from the page. I am able to retrieve the posts from the same facebook page. Here is the code snippet -

While using the below code to get private messages from a facebook page, we get following errors :
 
Code  1 :
 
String strFbQuery = "select name,total_count,unread_count from mailbox_folder where viewer_id=" + strPage_ID;          
List<JsonObject> strFbQueryResult = facebookClient.executeQuery(strFbQuery, JsonObject.class);
 
throws exception :
 
Received Facebook error response (code 606): You can only fetch messages for one user
