hi,
<html:select > works best with a collection of
dataobjects.
use
<html:select property="sdf">
<html:optionsCollection property="arrList"/>
</html:select >
here arrList could be arraylist of name value pairs,
something like
ArrayList arrList = new ArrayList();
arrList.put(new LabelValueBean("label","value"));
arrList.put(new LabelValueBean("label1","value2"));
arrList.put(new LabelValueBean("label2","value2"));
LabelValueBean class is provided by struts
AFAI hashtable does't fit in here.
u will have to iterate thro' the hashtable , if u want to still use
the hashmap
or go by arraylist to make things easier

Subject: doubt with
dropdown list box
hi,
I'm a newbie to STRUTS.
I have a doubt in
pre-populating a dropdown listbox in Struts ..while
loading the JSP
itslef the listbox has to be populated.
I have a JavaBean wich has a
method called getDetailsinHt() which is
returning hashtable
its
something like this- ht.put((new Long(LoginId )),sDetails);
sDetails is
a String array - String[] sDetails = new String[4];
this string array
contains first,middle and last names
How canI do this.I havebeen doing
this since hours but in vain..:(
someody plez help me.
The code
is like this:
Test
{
public Test{}
public long
id;
public String name[];
public long getId() {
return
(id);
}
public void setId(long id) {
this.id =
id;
}
public String[] getNames() {
return
this.name;
}
public void setName(String[] name) {
this.name =
name;
}
public Hashtable getDetailsinHt()
{
Hashtable ht=new
Hashtable();
String[] sDetails = new String[4];
sDetails[0] =
"Name";
sDetails[1] = "Name";
sDetails[2] = "Name";
ht.put((new
Long(LoginId )),sDetails);
return ht;
}
}
in my
ActionForm I'm writing theget andset methods like
public Hashtable
getUserId() {
return userId;
public void setUserId(Hashtable
userId) {
this.userId= userId;
}
public Hashtable
getList()
{
UserList iab=new UserList();
try
{
Hashtable
users=iab.getUserList(0);
}catch(Exception e){}
return
users;
}
and in my JSP
I'm giving as
<bean:define
id="list" name="createIssueForm"
property="userId"
type="java.util.Hashtable"/>
<html:select
property="users" size="1">
<html:options collection="list"
property="id"
labelProperty="name"/>
</html:select>
but
I'm not able to populate the list box.....here I guess I'm
doing
something wrong with the
------ property="id"
labelProperty="name"/>
Can somebodt plez tellme where I'm
wrong??
Thanx
