Question

I am using hashmap and set it in session.in s:select tag.

<s:select name="language" id="language" headerKey="-1"   headerValue="All Languages" cssStyle="width:210px" list="#session.languages"  />

While accessing map in jsp using getting following error sometime,

org.apache.jasper.JasperException: org.apache.jasper.JasperException: tag 'select', field 'list', name 'language': The requested list key '#session.languages' could not be resolved as a collection/array/map/enumeration/iterator type. Example: people or people.{name} - [unknown location]

Please advice on the issue.

Answer 1

struts2 doesn’t recognize your object type, you should do this.

<s:select name="language" list="#session.languages" listKey="id" listValue="name" />
