How to delete secondary content items attached to a WTDocument using Api?

[JarrettOberg · Accepted solution]

Hi Vineeth,

Here is an example:

document = (WTDocument)ContentHelper.service.getContents(document);

String number = document.getNumber();

/* Get the list of ContentItem out of the passed ContentHolder This should be done after a call to ContentHelper.service.getContents( ContentHolder ). Note this will NOT return the primary content for a FormatContentHolder.*/

Vector contents = ContentHelper.getContentList(document);

int num_of_files = contents.size();

System.out.println("Removing " + num_of_files + " content items from " + number);

for (int i = 0; i < num_of_files; i++)

{

ContentItem ci = (ContentItem)contents.elementAt(i);

System.out.println("Removing content item: " + ci.getDescription());

ContentServerHelper.service.deleteContent(document,ci);

}

Thanks,

Jarrett

Also you may have to check out the object to avoid locks.

My requirement is to create a EPMDoc and Iterate it.as like below.

EPMDocA.prt  -- A.1 -- epmdcoa.prt (50kb Size file )

again itrate it to become,

EPMDocA.prt  -- A.2 -- epmdcoa.prt (100kb Size file ).

now i am able to create EPMDocA.prt  -- A.1 -- epmdcoa.prt (50kb Size file ) with my program. and also able to check out the EPMDocA.prt for updating its content with modified cotent file for A.2 version.

but i am facing below error,
