Need to help to retrieve the value of forms
Hi
I have confronted by a problem to retrieve the value of form where the type is -> enctype:"multi/form-data"
i can't use the method request.getParameter("valueOfForms") ;
i don't know Why ... the result of this method is null.
If i use the type by defaut that means : enctype:"application/x-www-form-urlencoded" i can retrieve the value of Form
Have you got an idea how can i resolve my problem?
thanks you

i don't use common.fileUpload i use an program which was coded by developor. That program works correctly , i can upload through the server.
My problem is how can i retrieve value of my forms with form type= enctype: "multipart/form-data"
im going to illustrate by sample code :
< fom action="valid.jsp" name="general" enctype="multipart/form-data">
Name of File = < input type ="file " name =" fileUpload">
<input type="submit" value="ok">
</form>
< -file valid.jsp-->
<% String fileUpload = request.getParameter("fileUpload");
out.print(fileUpload);
%>

Hi ,
It didn't work because the HTML is not valid - it needs to be valid at least to a certain degree.
A few problems I found:
opening < fom tag is misspelled, it should be <form ,
There's a space inside the type attribute and the name attribute, remove all spaces inside html attributes to ensure consistency in naming of request parameters and form fields.
Try this modified code it should work:
index.jsp
--
><%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head><title></title></head>
<body>
<form action="valid.jsp" name="general" enctype="multipart/form-data">
Name of File = <input type="file" name="fileUpload"/>
<input type="submit" value="ok"/>
</form>
</body>
</html>
valid.jsp
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head><title></title></head>
<body>
<% String fileUpload = request.getParameter("fileUpload");
out.print(fileUpload);
%>
</body>
</html>

You can use any attribute name you want, as long as the HTML input text field name , and the one used by request.getAttribute are exactly the same - no spaces , also the case should match.
I've tried the above code, and it prints the full path of the file bieng uploaded, it did not show null after I made the corrections.
If you are still having problems, create a fresh new file and copy the code exactly as you see it above and try it out.
