How to access teh form field in JSP

Can you provide a code snippet on how to access the form field in the JSP page. It doesn’t seem to be coming as part of request. There is a FileItem with field name as the one i send but how to get that value?

This is my JS code.

vault.setFormField(“FORWHAT”, forWhat);


there was a sample below in this forum, i will find it now for you, one moment.
