Method Details

clientDeleteRequest

public static void clientDeleteRequest(ClientView clientViewBean,
 ClientViewHelper clientViewHelper)

Handles a client's request to delete a document. If its a data document, it removes the Doc Id from the FGDC metadata in the Metacat database. It determines what metadata Doc ID is including this Doc Id. It then queries metacat for the parent FGDC document and removes the Doc Id from it, and reloads the new version with a new revision number. If its a metadata document, it deletes any related data documents, then it deletes the metadata. In either instance, it sets the server feedback in the session ("updateFeedback").

Parameters:

request - HttpServletRequest which contains docId parameter.

 HashMap dataDocIDs,
