<%response.setContentType("text/html");
String pid = request.getParameter("id");
System.out.println(pid);
int propid=Integer.parseInt(pid);
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection conn= DriverManager.getConnection("jdbc:odbc:rama");
String contentType = request.getContentType();
if ((contentType != null) && (contentType.indexOf("multipart/form-data") >= 0)) {
DataInputStream in = new DataInputStream(request.getInputStream());
int formDataLength = request.getContentLength();
byte dataBytes[] = new byte[formDataLength];
int byteRead = 0;
int totalBytesRead = 0;
while (totalBytesRead < formDataLength) {
byteRead = in.read(dataBytes, totalBytesRead, formDataLength);
totalBytesRead += byteRead;
String file = new String(dataBytes);
String saveFile = file.substring(file.indexOf("filename=\"") + 10);
saveFile = saveFile.substring(0, saveFile.indexOf("\n"));
saveFile = saveFile.substring(saveFile.lastIndexOf("\\") + 1,saveFile.indexOf("\""));
saveFile=saveFile.substring(saveFile.lastIndexOf("."),saveFile.length());
saveFile= pid + saveFile;
//out.print(dataBytes);
int lastIndex = contentType.lastIndexOf("=");
String boundary = contentType.substring(lastIndex + 1,contentType.length());
int pos;
pos = file.indexOf("filename=\"");
pos = file.indexOf("\n", pos) + 1;
pos = file.indexOf("\n", pos) + 1;
pos = file.indexOf("\n", pos) + 1;
int boundaryLocation = file.indexOf(boundary, pos) - 4;
int startPos = ((file.substring(0, pos)).getBytes()).length;
int endPos = ((file.substring(0, boundaryLocation)).getBytes()).length;
String saveFilepath="upload/" + saveFile;
FileOutputStream fileOut = new FileOutputStream(saveFilepath);
//fileOut.write(dataBytes);
fileOut.write(dataBytes, startPos, (endPos - startPos));
fileOut.flush();
fileOut.close();%>

Hi Sandesh,
this is simply not supported, not in WebDynpro nor in standard HTML.
A workaround is to upload a ZIP with all files and on server side unpack the ZIP and operate on the single files.
I hope it will  help u..

As you know using File upload UI element we can upload only one file at a time. There may be a scenario where user may want to upload any no of files at a time which is not determined at design time. This can be acheived using the ACF UpDownload UI element which requires a security whiltelist to be created

You can use Table UI element.
