If all you want to do is validate form fields, JavaScript is probably the

Subject: Re: Getting form parameters
Could you tell me how i can use the two forms??
basically i am having this problem becos i need to validate the text fields
before i go ahead and upload the file to the database and so the multipart
request which goes through the inputstream doesnt work well.
Maybe i can use the two forms too?
Thanks.
