How Do I Create This Drop-Down List in Struts?
My ArrayList is a collection of bean object. The
ArrayList is created this way:
public Collection findEditors( String userrole, String
category )
{
..........
EditorBean editorBean = null;
ArrayList editors = new ArrayList();
// database access code
while( rs.next() )
{
editorBean = new EditorBean(
rs.getString("user_name") );
editors.add( editorBean );
}
return editors;
.......
}
and my EditorBean is like:
public class EditorBean
{
private String name;
public EditorBean() {}
public EditorBean( String name )
{
this.name = name;
}
public String getName() {
return Name;
}
public void setName( String name ) {
this.name = name;
}
}
After "editors" is returned, I create a session
object:
session.setAttribute( "EDITORS", editors );
How do I create a drop-down list for this collection
of editors?
<html:select size="1" property="??????"
multiple="false">
<html:options collection="??????" property="name"
labelProperty="name"/>
</html:select>

The collection that you want to iterate through and the form property
aren't linked as such only when you nest the html:options tag in the
html:select tag
So your html:select form property is like any other form property, and
when submitted will only the form property will be set to only one
value from the list.
<html:select property="editor">
//now the list in the options tags is only really associated
//with the form property as its nested in the html:select
<html:options collection="mycollection"
the property attribute in the html:options tag is to drill to the
property of the bean thats exposed during the iteration and hasn't much
to do with the form itself.

You should have a property in your form bean where the user selection will
go. In this case the property is "name"
<html:select size="1" property="Property in the form bean to hold the
selection"
multiple="false">
<html:options collection="EDITORS" property="name"
labelProperty="name"/>
</html:select>
