Do it in the action?

Hi,
 
Looking for  aeasy way to sort entries in the drop down in my jsp, that
are populated using the bean and html: select tag with options:
collection:
 
my code as of now is below:

select name=fullName style=width:225px

logic:iterate id=teacher name=teachers option value=bean:write
name=teacher property =employeeID/

bean:write name=teacher property =fullName/

/option

/logic:iterate

/select

 

 

My other approach to create same drop down is:

html:select style=width:225px property=fullName 

html:options collection=teachers property=teacher
labelProperty=fullName/

/html:select

Thanks in advance

 Looking for  aeasy way to sort entries in the drop down in my

 with options: collection:
 my code as of now is below:
 html:select style=width:225px property=fullName 
 html:options collection=teachers property=teacher 
 labelProperty=fullName/
 /html:select

I do this to display a bunch of checkboxes sorted by either the account
number or the cost center. 

In the Action:
  HttpSession session = request.getSession();
  Map accountMap = (Map) session.getAttribute( accountMap );
  Map newMap = new TreeMap( new CostCenterComparator() );
  newMap.putAll( accountMap );
  session.setAttribute( accountMap, newMap );
  accountMap = null;

And now the Map sitting in session scope is sorted by cost center.
Sorting it by Account is the natural order, so I just make a new TreeMap
with no Comparator, and dump the items in.

It's a little different with List than Map.  What type of Collection is
'teachers'?

And you don't have to put it in the session, it might be in the request,
or be a form property.

You can also use the BeanComparator class from the commons package instead 
of writing your own Comparator class.

It's pretty fast and allows for more flexibility (i.e. passing in the sort 
property, etc etc)
