if (MultipartFormDataRequest.isMultipartFormData(request)) {
                        // Uses MultipartFormDataRequest to parse the HTTP request.
                        MultipartFormDataRequest mrequest = new MultipartFormDataRequest(request);
                        String todo = null;
                        String filename=null;
                        String description=request.getParameter("txtDesc");
                        String checkfilename=mrequest.getParameter("uploadfile");
                        if (mrequest != null) todo = mrequest.getParameter("todo");
                        if ( (todo != null) && (todo.equalsIgnoreCase("upload")) ) {
                            Hashtable files = mrequest.getFiles();
                            if ( (files != null) && (!files.isEmpty()) && (description!=null)) {
                                UploadFile file = (UploadFile) files.get("uploadfile");
                                if (file != null){
                                    filename=file.getFileName();                                    if(checkfilename==null){
                                        filename="";
                              upBean.store(mrequest, "uploadfile");  // Uses the bean now to store specified by jsp:setProperty at the top.
                                         else out.println("<BR> todo="+todo);

Thanks for reply.
I replaced messageFileUpload (binded to blob table column) with messageStyledText (binded to filename attribute). Above the table placed single messageFileUpload and submitButton nearby. After user select file on submit I do:
*if (pageContext.getParameter("DoUploadButton") != null) {*
.. DataObject fileUploadData = pageContext.getNamedDataObject("FileData");
.. *if (fileUploadData != null) {*
.... String fileName = (String)fileUploadData.selectValue(null, "UPLOAD_FILE_NAME");
.... String contentType = (String)fileUploadData.selectValue(null, "UPLOAD_FILE_MIME_TYPE");
.... BlobDomain fileContent = (BlobDomain)fileUploadData.selectValue(null, fileName);
.... String seqNumber = pageContext.getParameter("seqNumber");
.... am.insertInstanceAttachRowBlob(seqNumber, fileName, fileContent, contentType);
.... pageContext.removeNamedDataObject("FileData");
.. return;
