To Upload and insert the file  into Database with Current Date and Time In JSP


In this tutorial, you will learn how to upload a file through JSP and insert it into the database. For this, we have created two jsp pages page.jsp and upload_page.jsp. The page.jsp is created for presentation where a file component is created to let the user select the file to be uploaded and a button to submit the request. The action is performed on upload_page.jsp. Before proceeding further, we need table in database. We created table named 'file' for our example.

Step 1 : Create a Table structure for file

CREATE TABLE `file_tbl` (
`id` bigint(20) NOT NULL auto_increment,
`file_data` text,
`file_date` datetime default NULL,

Table "file" is created.

Step 2:Create a Page ("page.jsp") To Upload a file. 

<%@ page language="java" %>
<HEAD><TITLE>Display file upload form to the user</TITLE></HEAD> 

<BODY> <FORM ENCTYPE="multipart/form-data" ACTION=
"upload_page.jsp" METHOD=POST>
<table border="0" bgcolor=#ccFDDEE>
<td colspan="2" align="center"><B>UPLOAD THE FILE</B><center></td>
<td colspan="2" align="center">&nbsp;</td>
<td><b>Choose the file To Upload:</b></td>
<td><INPUT NAME="file" TYPE="file"></td>
<td colspan="2" align="center">&nbsp;</td>
<td colspan="2" align="center"><INPUT TYPE="submit" VALUE="Send File" ></td>

Step 3: Create a page of upload_page.jsp to upload and insert the file in database with current date and time.

<%@ page import="*,java.sql.*,java.util.*,java.text.*,java.text.SimpleDateFormat" %>
int val =0;
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 =, totalBytesRead, formDataLength);
totalBytesRead += byteRead;
String file = new String(dataBytes);
String saveFile = file.substring(file.indexOf("filename=\"") + 10);
System.out.println("saveFile=" + saveFile);
saveFile = saveFile.substring(saveFile.lastIndexOf("\\")+ 1,saveFile.indexOf("\""));
System.out.println("saveFile" + saveFile);
saveFile = file.substring(file.indexOf("filename=\"") + 10);
saveFile = saveFile.substring(0, saveFile.indexOf("\n"));
saveFile = saveFile.substring(saveFile.lastIndexOf("\\")+ 1,saveFile.indexOf("\""));
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;

FileOutputStream fileOut = new FileOutputStream(saveFile);
fileOut.write(dataBytes, startPos, (endPos - startPos));

Connection con=null;
PreparedStatement pstatement = null;
String line = null;
String value=null;
String url = "jdbc:mysql://localhost:3306/";
String dbName = "file_upload";
String driver = "com.mysql.jdbc.Driver";
String userName = "root"; 
String password = "root";
StringBuilder contents = new StringBuilder();
BufferedReader input = new BufferedReader(new FileReader(saveFile));
while (( line = input.readLine()) != null){
value = contents.toString();
con = DriverManager.getConnection(url+dbName,userName,password);
java.util.Date now = new java.util.Date();
String DATE_FORMAT = "yyyy-MM-dd hh:mm:ss";
SimpleDateFormat sdf = new SimpleDateFormat(DATE_FORMAT);
String strDateNew = sdf.format(now) ;

String queryString = "INSERT INTO file_tbl set file_data='"+value+"',file_date='"+strDateNew+"'";



val = pstatement.executeUpdate();

<b>File <% out.println(saveFile); %> has been uploaded and inserted into Database at <%=strDateNew%>.</b>

catch(Exception e)

This file upload and insert into database with current date and time using JDBC database.  This can be done

(i). To import*,java.sql.*,java.util.*,java.text.*,java.text.SimpleDateFormat  packages. Packages is used to read and write the file uploaded having classes like DataInputStream, FileOutputStream etc.  java.util.*,java.text.*,java.text.SimpleDateFormat is used to retireve the current Date and Time. 
(ii). Prepared Statement is used to insert the data into database having used pstatement=con.prepareStatement(queryString);
(iii). Using a Query "INSERT INTO file_tbl set file_data='"+value+"',file_date='"+strDateNew+"'" to insert the data into database.

Step 4: Output when file upload and insert into database with current date and time.

Table Structure after file Upload : 

A message has been displayed on the browser.

The file  is inserted into the database with current date and time.
