I have a Struts2 application. On jsp page I use selectbox to populate ArrayList from database:

<s:select name="country" list="countryList" listKey="countryId" listValue="countryName" headerKey="0" headerValue="Country" label="Select country" />

But I need to store in listKey not an id but index of ArrayList. So then I read this index, find the appropriate country in ArrayList and retrieve it. Is it possible?

    Try using countryList.indexOf(country) as below:

    <s:select name="country" list="countryList" listKey="countryList.indexOf(country)" 
                                           listValue="countryName" headerKey="0"  
                                   headerValue="Country" label="Select country"/>
