    Default How to get the values from one jsp page to another jsp page

    I have one jsp page with two text fields and one file upload button. Successfully i can upload the file to a specific folder.

    But the problem is when i am trying to get the values from those textfields in another jsp/servlet, i got null values for the textfields. I have written the code in second jsp page for both uploading and get the values of textfields.Please help me.

    Thanks in Advance.

    My second jsp page code is below:

    import com.ajel.Getcon;
    import java.sql.Connection;
    import javax.servlet.ServletException;
    import javax.servlet.http.HttpServlet;
    import javax.servlet.http.HttpServletRequest;
    import javax.servlet.http.HttpServletResponse;

    * Servlet implementation class Upload
    public class Upload extends HttpServlet {
    private static final long serialVersionUID = 1L;

    protected void doPost(HttpServletRequest req, HttpServletResponse res) throws ServletException, IOException {
    PrintWriter out=res.getWriter();
    String rname=req.getParameter("recruiter");
    String contentType = req.getContentType();
    try {
    Connection con=Getcon.getConnection();
    } catch (Exception e) {
    // TODO Auto-generated catch block
    if ((contentType != null) && (contentType.indexOf("multipart/form-data") >= 0)) {
    DataInputStream in = new DataInputStream(req.getInputStream());
    //we are taking the length of Content type data
    int formDataLength = req.getContentLength();
    byte dataBytes[] = new byte[formDataLength];
    int byteRead = 0;
    int totalBytesRead = 0;

    //this loop converting the uploaded file into byte code
    while (totalBytesRead < formDataLength) {
    byteRead =, totalBytesRead,formDataLength);
    totalBytesRead += byteRead;
    String file = new String(dataBytes);
    //for saving the file name
    String 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;
    //extracting the index of file
    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;
    // creating a new file with the same name and writing the content in new file
    saveFile="E:\\workspace\\Ajelsite\\Resumes\\"+save File;
    FileOutputStream fileOut = new FileOutputStream(saveFile);
    fileOut.write(dataBytes, startPos, (endPos - startPos));


    out.println("File saved as " +saveFile);

    Use opensource fileupload apis like cos.jar or apache-commons-fileupload which allow you to read both the file and the parameters submitted with the file.
    To get the parameters to display on the second JSP you'd need to set them in some scope (request or session) in the servlet before forwarding to that second JSP.
