hi dear’s

I am caught in the problem that when i use “Form ENCTYPE=”multipart/form-data” and Method=”Post” and ACTION=”FileProcess.jsp” then i am get the file on FileProcess.jsp but i can’t get the other data

like example Problem Post by that Some Person

http://www.velocityreviews.com/forums/t137597-html-file-upload-using-enctype-multipart-form-data-in-form.html

Should we use enctype=multipart/form-data in the form, I know it is recommended
if the form has <input type=”file”>. My form has and other
html controls.

I tried the following,

form.html
=========
”

POST” enctype=multipart/form-data>”
”

 

<input type=text name=”name” size=80>”
”

filename” size=80>”
”

<input type=”submit” value=”Upload File Test”>’
“</FORM>”

test.jsp
=========
<p><%= “filename = ” + request.getParameter(“filename”) %>
<p><%= “name = ” + request.getParameter(“name”) %>

It will output
filename = null
name = null

I don’t understand why, but if i remove enctype=multipart/form-data in the form,
then I am able to get the data.
Please advise. Thanks!!

Now i think you Have Clear Picture in Your Mind …….

Now i am going to tell you solution which i get From My RND and Try………..

1)Test.jsp

"!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
html
 "   head
script
             var e="";
function selValue(){
                //  alert('me there');
                e = document.getElementById("name");
                //   alert('me there ='+e);
                if(e=="")
                {
                    alert('Please Select');

                }else{

                    window.location.replace("Accountdetials.jsp?value="+e);
                }//  window.location="<%= request.getContextPath() + "/Test.jsp"%>"+"?value="+e;

            }
/script
<scriplet 
String selectedindex = "";

            String AccountStatus = request.getParameter("value");
            if (AccountStatus != null) {

                System.out.println("value=" + AccountStatus);
                session.setAttribute("AccountStatus", AccountStatus);

            } else {
                session.setAttribute("AccountStatus", null);
            }
/secriplet

body
FORM ENCTYPE="multipart/form-data" ACTION="FileProcess.jsp" METHOD=POST>

center>
table border="0" bgcolor=#ccFDDEE>
tr>UPLOAD THE FILE
tr> 
INPUT NAME="name" TYPE="text"
Choose the file To Upload:
INPUT NAME="file" TYPE="file"

input type="submit" value="Send File"

 In above page you see one is <input and="" other="" input="" now="" when="" we="" use ="" "form="" enctype="multipart/form-data" then="" can't="" get="" data="" on="" page="" like="" that 
 boz now you data is send in multiparts for that reason we get file data like that which i tell in the below  FileProcess.jsp  now get the file data in the below page but not get the intput Type="text" data ..... now for that i use JAVASCRIPT like that now you can see the above Javascript function selValue(); then scriptlet of jsp how i put it in the session now when 
you press the Submit button the value of input text is all ready in the session .... now on next action jsp page just 
get that value from session 
I can do this on the Select Option tag ...... 

2)FileProcess.jsp

<scriplet
int totalRows = 0;
    String saveFile = "";
    String contentType = request.getContentType();
    if ((contentType != null) && (contentType.indexOf("multipart/form-data") >= 0)) {
        DataInputStream in = new DataInputStream(request.getInputStream());
        System.out.println("dddda  === \n " + in.toString());
        int formDataLength = request.getContentLength();
        pi_filesize = formDataLength / 1024;        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);
        saveFile = file.substring(file.indexOf("filename=\"") + 10);
        //System.out.println(saveFile + "\t 1" + file.toString());
        saveFile = saveFile.substring(0, saveFile.indexOf("\n"));
        // System.out.println(saveFile + "\t 2");
        saveFile = saveFile.substring(saveFile.lastIndexOf("\\") + 1, saveFile.indexOf("\""));
        // System.out.println(saveFile + "\t 3");
        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;
        // saveFile = "C:/" + saveFile;
        File f = new File(saveFile);
        FileOutputStream fileOut = new FileOutputStream(f);
        fileOut.write(dataBytes, startPos, (endPos - startPos));
        fileOut.flush();
        fileOut.close();
