Am getting java.lang.IndexOutOfBoundsException while I try to uplaod a file to server.
I checked the code at loaclhost and it was working fine,
but after uploading it to the server am getting the error.
upload.jsp
<form action="UploadServlet" method="post" enctype="multipart/form-data">
<input type="file" name="select" value="" />
<input type="submit" value="Select Profile Pic" />
</form>
