Question

How to populate ddropdown list in a web page in struts2 from database. The items of the drop down will be taken from database.

Answer 1

For creating list in struts2, we can use implement Preparable.

public class CountryListAction extends ActionSupport implements Preparable {

 private List<String> country;
 getters and setters 

 public String prepareCountryList() throws Exception{

  country=new ArrayList<String>();
  country=fill country from database;

 }

 public String countryList() throws Exception{
  return SUCCESS;
 }

} 

For jsp, use:

<s:select label="Select Country"
   name="country"
   headerValue="Select Country"
   list="%{country}"
/>

Preparable interface will call prepareCountryList method before calling countryList and jsp will be prepopulated. You can populate as many drop down list using single method in struts2.
