Subject Re: Passing parameters to a bean from a JSP
Date Mon, 03 Apr 2000 15:56:41 GMT
The request.getParameterNames() and request.ParameterValues() are returning 
null. I am pulling values from the FORM using JavaScript so I know that the 
fields are there and that they have values. How do I initialize the request 
object so that I can pull FORM values from it?
