Answer 1

I know it's an old question, but I had similar issue today. I used DLFileEntryLocalServiceUtil, and I had to call both addFileEntry() and updateFileEntry() in order to correctly create the asset.

See Liferay DLFileEntryLocalServiceUtil.addFileEntry does not create AssetEntry record

Answer 2

Try this code snippet

ThemeDisplay themeDisplay = (ThemeDisplay) actionRequest.getAttribute(WebKeys.THEME_DISPLAY);
ServiceContext serviceContext = ServiceContextFactory.getInstance(actionRequest);

File file = uploadRequest.getFile("file");
String contentType = MimeTypesUtil.getContentType(file);

InputStream inputStream  = new FileInputStream(file);

Folder folderName = DLAppLocalServiceUtil.getFolder(parentRepositoryId, 
                                                    parentFolderId, 
                                                    "Folder Name");
long folderId = folderName.getFolderId();
long repositoryId = folderName.getRepositoryId();

FileEntry fileEntry = DLAppLocalServiceUtil.addFileEntry(themeDisplay.getUserId(), 
                                                         repositoryId, 
                                                         folderId, 
                                                         file.getName(), 
                                                         contentType, 
                                                         "File Name", 
                                                         "description", 
                                                         "changeLog", 
                                                         inputStream, 
                                                         file.length(), 
                                                         serviceContext);
