Getting "not a multipart request" even though the image is being saved.

[chaitanya karthikk]

Hi everybody, I am chaitanya, I have developed a small application to register users. The form sends a multi part request.

Here the server is able to catch the image and is saving the image in c:\vitsimages\

But after that it is saying the request is not a multipart request.

the code goes like this

new_faculty.jsp

<c:choose> 
	<c:when test="${sessionScope.admin!=null}">
		<form method=post name=myform action=newFac onSubmit='return valid()' method=get enctype="multipart/form-data">

please anyone tell me what is the mistake in it. I am trying to figure it out from morning. But all my tries failed

Thank you all in advance.

I am extremely sorry, I figured the problem out. I am sending request to the same servlet again. So I got that error.

response.sendRedirect("newFac"); //the problem lies here

response.sendRedirect("new_fac.jsp"); //it must be something like this
