    Default The method getPart(String) is undefined for the type HttpServletRequest

    my servlet code is:

    package Servlet;
    import java.io.IOException;
    import java.io.InputStream;
    import java.sql.Connection;
    import java.sql.DriverManager;
    import java.sql.PreparedStatement;
    import java.sql.SQLException;
    import javax.servlet.ServletException;
    import javax.servlet.annotation.MultipartConfig;
    import javax.servlet.annotation.WebServlet;
    import javax.servlet.http.HttpServlet;
    import javax.servlet.http.HttpServletRequest;
    import javax.servlet.http.HttpServletResponse;
    import javax.servlet.http.Part;
    * Servlet implementation class FileUploadDBServlet
    @MultipartConfig(maxFileSize = 10177215) // upload file's size up to 16MB
    public class FileUploadDBServlet extends HttpServlet {
    private static final long serialVersionUID = 1L;
    * @see HttpServlet#HttpServlet()
    public FileUploadDBServlet() {
    private String dbURL = "jdbc:mysql://localhost:3306/ecomtest";
    private String dbUser = "root";
    private String dbPass = "admin";
    protected void doPost(HttpServletRequest request,
    HttpServletResponse response) throws ServletException, IOException {
    // gets values of text fields
    String firstName = request.getParameter("firstName");
    String lastName = request.getParameter("lastName");
    InputStream inputStream = null; // input stream of the upload file
    // obtains the upload file part in this multipart request
    Part filePart = request.getPart("photo");
    if (filePart != null) {
    // prints out some information for debugging
    // obtains input stream of the upload file
    inputStream = filePart.getInputStream();
    Connection conn = null; // connection to the database
    String message = null; // message will be sent back to client
    try {
    // connects to the database
    DriverManager.registerDriver(new com.mysql.jdbc.Driver());
    conn = DriverManager.getConnection(dbURL, dbUser, dbPass);
    // constructs SQL statement
    String sql = "INSERT INTO datawithimage (first_name, last_name, photo) values (?, ?, ?)";
    PreparedStatement statement = conn.prepareStatement(sql);
    statement.setString(1, firstName);
    statement.setString(2, lastName);
    if (inputStream != null) {
    // fetches input stream of the upload file for the blob column
    statement.setBlob(3, inputStream);
    // sends the statement to the database server
    int row = statement.executeUpdate();
    if (row > 0) {
    message = "File uploaded and saved into database";
    } catch (SQLException ex) {
    message = "ERROR: " + ex.getMessage();
    } finally {
    if (conn != null) {
    // closes the database connection
    try {
    } catch (SQLException ex) {
    // sets the message in request scope
    request.setAttribute("Message", message);
    // forwards to the message page
    getServletContext().getRequestDispatcher("/submit.jsp").forward(request, response);
