How to fetch object properties from selected object in Struts 2

Question

I have a list of City objects with name and id fields. I use Struts2 and I a have jsp page with a select tag.

Answer 1

To set id to the value of the select tag you should use additional attributes

<s:select label="Source city" 
          list="cities" 
          listKey="id"
          listValue="name"
          name="sourceId"/>
