Hi Stefan
I think this is how u should do it
<bean:define name="YourFormName" id="names"
property="nameArrayList" />
<html:select property="selectedName">
<html:options collection="names" property="value"
labelProperty="label" />
</html:options>
Here retrieve the names in your Action class using -ArrayList getAllNames().
Set that ArrayList to your ActionForm . Then in Jsp file use <html:select>
amd <html:options> tag to show those Names present in your ActionForm as
ArrayList
Here create <bean:define> tag which will expose ur ArrayList present in the
ActionForm as a scripting variable - "names"
Then give that as the collection attibute value to <html:options > tag .
Here U need to mention the value and labelProperty attributes.
I mean the ArrayList contains the objects say - NameLabelValue And in that
have getter "value" and " label" methods
like
Class NameLabelValue implements Serializable {
private String name;
public String getValue( ) {
return name; // this will displayed in the drop down list
as option
}
public String getLabel() {
return name; // this is label corresponding to above option
which will be send to server when u select a option
}
}
So basically the ArrayList called "nameArrayList" present in your
ActionForm should contain objects of above classes .
Please contact me if u need any help in this

Subject: Problems with select ans iterate
When I start the site, I get the fallowing error message:
"Cannot find bean mitarbeiter in scope null"
The code I wrote is:
<select name="select" size="7" class="textbox">
<logic:iterate id="mitarbeiter" name="allMitarbeiter" >
<option><bean:write name="mitarbeiter" property="value"/></option>
</logic:iterate>
</select>
The JSP-Site has the name verwaltung.jsp and allMitarbeiter is an Attribute
in the VerwaltungForm.java and in this file there is an getAllMitarbeiter()
methode which returns a ArrayList. This ArrayList includes some Strings.
How can I do this?
I hope someone can help me
Stefan
