Thread: FAILED TO OBTAIN COLLECTION

I was developing a standalone application under struts 1.x framework.
I need to do create dropdowns in jsp using struts tags.I have created using <options:collection>tag and created getters and setters for the property in form also.But the dropdown was not getting populated with all data.only some data was getting populated at last it showing an servlet exception :Failed to obtain collection in the dropdown.Can anyone please look into my issue....

--- Update ---

Experts,please look into my issue.I need to solve this as soon as possible Thanks in advance

This is the jsp code...


<html:select property="market" name="createcountryform" title="Please select Country" onchange="PopulateStatezone();">
<htmlption value="">Select One</htmlption>
<htmlptionsCollection name="createcountryform" property="countryList" value="countryCode" label="countryName" />
</html:select>



Form---
public class CreateCountryForm{

private List<CountryInfoDTO> countryList = null;

/**
* @return Returns the countryList.
*/
public List<CountryDTO> getCountryList() {
return countryList;



/**
* @param countryList
* The countryList to set.
*/
public void setCountryList(List<CountryDTO> countryList) {
this.countryList = countryList;
}
}





DTO---

public class CountryDTO{

private String countryCode = null;
private String countryName = null;


public String getCountryCode() {
return countryCode;
}
/**
* @param countryCode The countryCode to set.
*/
public void setCountryCode(String countryCode) {
this.countryCode = countryCode;
}
/**
* @return Returns the countryName.
*/
public String getCountryName() {
return countryName;
}
/**
* @param countryName The countryName to set.
*/
public void setCountryName(String countryName) {
this.countryName = countryName;
}
}

Action---

CreateCountryForm createCountryForm = new CreateCountryForm();
List<CountryDTO> countryList = new ArrayList<CountryDTO>();
createCountryForm.setMarketList(marketList);

Sorry for the wrong data in action..This is the code in action

Action----

CreateCountryForm createCountryForm = new CreateCountryForm();
List<CountryDTO> countryList = new ArrayList<CountryDTO>();
createCountryForm.setCountryList(countryList);
