I have been facing problems populating drop-downs using dummy stub classes .I have used a function to populate the page containing the drop-down and thrown the Action Form type object into the session.
Well you didn't create a function(method) for populating the dropdowns. You created some kind of method that is returning an ActionForm. Create a method called populate(..) that returns a Collection in your Action go do what you want and call that from your action methods. (If you arne't using a DispatchAction then just put the populate method in a base class or else maybe in some Helper class). I describe more here

Now how do I retrieve the values on to my jsp screen. Here is the code snippet..
*_Action Class_*:
………………
form = populate(request, iFlag);
session.setAttribute("com.itest.web.form.SelectionForm", form);
………………….
…………………..
*public* ActionForm populate(HttpServletRequest request)
{
SelectionForm form = *new* SelectionForm();
ArrayList arlproject = ProjectData.getProjects();
ListIterator iter = arlproject.listIterator();
*while* (iter.hasNext())
{
Project proj = (Project) iter.next();
System.out.println("++++++++++++++++" + (String)proj.getProjectcode());
form.setProjects((String)proj.getProjectcode());
}
*return* form;
}
*_SelectionForm.java_*
*_ _*
*public* *void* setProjects(String strProject) {
System.out.println("rrrrrrrrrrrrrrrrrr");
String strKey="proj"+index;
System.out.println("rrrrrrrrrrrrrrrrrr"+strKey);
*if* (*this*.htbSelect.containsKey(strKey))
{
index++;
strKey="proj"+index;
}
//this.htbSelect.remove("proj");
*this*.htbSelect.put(strKey,strProject);
System.out.println("rrrrrrrrrrrrrrrrrr"+index);
System.out.println("iiiiiiiiiiiiii"+htbSelect.get(strKey));
}
*public* ArrayList getProjects() {
ArrayList arlProject=*new* ArrayList();
System.out.println("111111111111111111111111111"+index);
*for*(*int* i=0;i<index;i++)
{
String strKey="proj"+i;
String proj=(String)*this*.htbSelect.get(strKey);
arlProject.add(proj);
}
*return*(arlProject);
}
