use struts framework and eclipse[to genrate get/set methods]
else you can use req.getParameterNames() or getParameterMap() .. but still I think you have to write those 60+ html elements at some point of time.

Adopting a framework just to auto-generate a handful of statements seems a bit extreme.
It might be helpful if you'd let on just what is you need to do with the 60+ parameter values.

Hi Dolly,
Here are 2 ways from my code-snippet-collection to simplify checking parameters for null:

There is one other way that I use a LOT when handling big requests likle this. Use:
req.getParamterNames() which returns an Enumeration of the incoming names along with a Hashtable to grab the incoming values like this:
Enumeration enum = req.getParameterNames();
Hashtable myInfo = new Hashtable();
while (enum.hasMoreElements()) {
String name = enum.nextElement();
myInfo.put(name, req.getParameter(name));
}
This is great when you have a ton of paramaters coming in & dont want to go thru the manual grabbing of every last one (OH what a pain)
Once you have everything in the Hashtable you can test & run thur them in a loop & away you go!....hope this helped.

i was just wondering whether ur field names are more or less the same.
If they r X1,X2... then u could loop them thru a for loop and pass it to request.getparameter();
for( int i = 0; i < 60 ; i++ )
{
S.O.P( request.getparameter("X"+i) );
}
This is just the skeleton,does it help??

Dolly,
May be using a javabean for the display is a good idea to populate all the form fields.
