and

http://www.mail-archive.com/[email protected]/msg08090.html

The problem is, I am sumitting other fields along with file field as listed below

<form action="index.jsp" method="post" enctype="multipart/form-data">
    <input name="name" type="text" value=""> <br/>
    <input name="imageField" type="file" size="30"> <br/>
    <input name="Submit" type="submit" value="Sumbit">
</form>

In my servlet I am getting null when querying

name = request.getParameter("name");

Why it is so? Is there a way to retrieve text field value?
