pls help me to solve the above problem

following is my coding detail..
method code for this is:-

public String execute() {
    	
    	if(this.username.length()==0){
    		addFieldError("username", "Please enter the First name User");
    	}
            return "success";
        
            
        }
    	
public String populate(){
    	
    	countryList = new ArrayList<Country>();
        countryList.add(new Country(1, "India"));
        countryList.add(new Country(1, "Shri Lanka"));
        countryList.add(new Country(1, "USA"));
        countryList.add(new Country(1, "Pakistan"));
        countryList.add(new Country(1, "NewsLnad"));
        
        zList =new ArrayList<String>();
        zList.add("Information Tech.");
        
        zList.add("Computer Eng.");
        zList.add("Mechnical.");
        zList.add("Civil");
        zList.add("Electrical");
        
        community = new String[]{"Information Tech.","Computer Eng."};
     	    	
		return "populate";
    	
    	
    }

and my struts.xml part is following for the above action..

<action name="formdataaction"
            class="UiAction" method="populate">
            <result name="populate">/Register.jsp</result>
        </action>
        <action name="registeraction"
            class="UiAction" method="execute">
            <result name="error">/Register.jsp</result>
            <result name="success">/sucess.jsp</result>
        </action>
    </package>
