How to programmatically change the status of some document in liferay 7?

[Abhishek Jain，修改在7 年前。]

I want to change the status of some document to approved in the Documents and Media portlet in liferay 7. For that I am using the below function in some jsp file:-

DLFileEntryLocalServiceUtil.updateStatus(themeDisplay.getUserId(), fileEntry1.getFileVersion().getFileVersionId() ,0, null, null);

But doing so I am getting the NullPointerException as follows:-

java.lang.NullPointerException

Here when I change the status of document to a non-zero value it is successfully updated but when I change the status to 0, I am getting the NPE. Can you tell me why and how to remove it? Thanx in advance..

Did you get any solution ??

Even i have same requirement .

[Abhishek Jain，修改在7 年前。]

I just passed the value as non null for servicecontext and workflowcontext in updatestatus() . The reference for servicecontext is by the following code :-

serviceContext = ServiceContextFactory.getInstance(com.liferay.document.library.web.internal.portlet.DLAdminPortlet.class.getName(), renderRequest);

whereas I got reference of workflowContext by the folowing code:-

Map<string, serializable> workflowContext =
			(Map<string, serializable>)serviceContext.removeAttribute(
				"workflowContext");
	if (workflowContext == null) {
		workflowContext = Collections.emptyMap();
	}</string,></string,>

And called the updateStatus() method as follows:-

DLFileEntryLocalServiceUtil.updateStatus(themeDisplay.getUserId(), fileEntry.getFileVersion().getFileVersionId() ,102, serviceContext, workflowContext);

Hope this helps..

Hi Abhishek ,

Thanks a lot for your suggestion . Its worked .

I have one more concern .
As soon document uploaded via Custom portlet , we are uploading document with status as "draft" .
draft records are not getting index , hence its not available for search ( we are retrieving documents using indexer ).
I have also tried do reindex as soon document uploaded still records are not getting indexing .

If You want to changes your document and media status programmatically from draft to Approved.Follow below code
long companyId = PortalUtil.getDefaultCompanyId();
Company companyObj = CompanyLocalServiceUtil.getCompany(companyId);
Group group = GroupLocalServiceUtil.getGroup(companyId, String.valueOf(companyId));

DLFolder folder = DLFolderLocalServiceUtil.getFolder(group.getGroupId(), PARENT_FOLDER_ID,
"SirswaPartnerDocuments");
int workFlowStatus = WorkflowConstants.STATUS_APPROVED;

dlFileEntry = DLFileEntryLocalServiceUtil.updateStatus(folder.getUserId(),dlFileEntry.getFileVersion().getFileVersionId(),workFlowStatus, serviceContext,new HashMap<String, Serializable>());
