If nay boy needs all code for above I can send all with java class and config file .
<html:options>
ARRAY information
ArrayList prod = new ArrayList();
prod.add( new org.apache.struts.util.LabelValueBean( "Widget", "20" ) );
prod.add( new org.apache.struts.util.LabelValueBean( "Sprocket", "29-2a" ) );
prod.add( new org.apache.struts.util.LabelValueBean( "Cog", "29s" ) );
prod.add( new org.apache.struts.util.LabelValueBean( "Dunsel", "943" ) );
LabelValueBean takes the first String argument as the displayed name and the second as
the value returned. We’ll see more about this in a bit.
Now that you have prod set up, you pass that as a session or request bean to the JSP.
request.setAttribute( Constants.PRODUCT_KEY, prod );
(the Constants.PRODUCT_KEY is set to our bean name: "products"; we use this to
centralize bean name management)
To use the data in the JSP, add the following code:
<html:select property="product_id" styleClass="prodselect" >
<html:options collection="products" property="value" labelProperty="label" />
</html:select>
Notes: product_id is the variable the JSP will set to the product ID value of the
product selected by the user. products is the name of the bean (it must match what is
in Contants.PRODUCT_KEY -- we probably could've said
... collection="<%= Constants.PRODUCT_KEY %>" ...
in place of hard-coding the name. The choice is up to you.
property="value" and labelProperty="label" are automatically set by
org.apache.struts.util.LabelValueBean, so only use the values shown here.
The resulting HTML will look something like:
<select name="product_id" size="1">
<option value="20">Widget</option>
<option value="29-2a">Sprocket</option>
<option value="29s">Cog</option>
<option value="943">Dunsel</option>
</select>
