import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionMapping;

public class LookupForm extends ActionForm{
private String symbol=null;

public String getSymbol(){
return (symbol);
}
public void setSymbol(String symbol){
this.symbol=symbol;

}
public void reset(ActionMapping mapping, HttpServletRequest request) {

this.symbol=null;
}
}

and Action class is:
package com.struts;
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;

public class LookupAction extends Action{
LookupForm lookupForm = null;

protected Double getQuote(String symbol){

if(symbol.equals("SUNW")){
return new Double(25.00);
}
return null;
}

public ActionForward execute(ActionMapping mapping, ActionForm form,
     HttpServletRequest request, HttpServletResponse response)
     throws IOException, ServletException {

Double price=null;
//default target to success
String target= new String("success");
if(form!=null){
//use the lookup form to get the request parameters
 lookupForm = (LookupForm)form;
String symbol= lookupForm.getSymbol();
price= getQuote(symbol);
}
//set the target to failure
if( price==null){

target = new String("failure");
}
else{
request.setAttribute("PRICE",price);
}
//forward to the appropriate view
return(mapping.findForward(target));

}
}
