Your form should have a way to initialize the
Form. Some people call an initialize method in the Form class from the
Action class like this:
myPageAction?do
where myPageAction.do calls a method from
myPageForm.java like this:
myForm.initializeVariables();
return
mapping.findForward("refresh");
This would essentially load up the arraylist and
any variables you want from the DB and then return control to the JSP in the
refresh.
Alternately, you could have a method in your JSP
that calls the initializeVariables(); function. That way, you could just
call the JSP (hyperlink to it) and it would call the initializeVariables()
method to load up the arraylist.
Either way, you would put the code listed below in
a method in your Form (ie. initializeVariables(); )
Hope this helps :-)

Subject: RE: Does anyone have a example
to generate a drop down list?
Thank you very much, Spencer,
I tried it out, it is working.
I
don't know where to put the code in the FORM, so I put it in the action
class. And I had to add this line of code in my
request.setAttribute("org.apache.struts.taglib.html.BEAN",
form)
to
make it working.
So
where should I put the code to create the arrays? Why did I have to put
the line in?
THanks a lot,
Joyce

IN FORM:
// Get all xxx Values
for DropDown.
xxxDropDown[] results =
profileSession.getxxxValues();
//
Create the arrays for the labels and values.
xxxLabels
= new ArrayList();
xxxValues = new
ArrayList();
// For each value
returned...
for (int i = 0; i < results.length; i
++)
{
// Add a label and a
value to the corresponding
list.
xxxLabels.add(new
String(results[i].getLabel()));
xxxValues.add(new
String(results[i].getValue()));
}
IN JSP:
<html:select
property="selectedValue">
<html:options property="xxxValues"
labelProperty="xxxLabels"/>
</html:select>
Make sure to define the xxxLabels and xxxValues
as type ArrayList and import the class.
Hope this helps! :-)

Assuming I have a object method returning a list of
values. Does anyone have a example to generate a drop down
list?
