Create a Read Only VO CountriesLookup.

Query : SELECT distinct(loc_name) FROM country.
Bind Variable :     Name="SearchCriteria"
    Kind="viewcriteria"
    Type="java.lang.String"/>

View Criteria :
    Name="CountriesLookupCriteria"
    ViewObjectName="neelmani.model.queries.CountriesLookup"
    Conjunction="AND">
   
     
                  Name="displayOperators"
          Value="InAdvancedMode"/>
                  Name="autoExecute"
          Value="false"/>
                  Name="allowConjunctionOverride"
          Value="true"/>

          Value="true"/>
                  Name="mode"
          Value="Basic"/>
     
   
          Name="vcrow39"
      UpperColumns="1">
              Name="CountriesLookupCriteria_vcrow39_LocName"

        Operator="STARTSWITH"
        Conjunction="AND"
        Value=":SearchCriteria"

        Required="Optional"/>
   
 

---------------------------------------------------------
Put the bellow code in CountriesLookupImpl.(countriedLookup View Object)

    /**
     * Returns the variable value for SearchCriteria.
     * @return variable value for SearchCriteria
     */

    public String getSearchCriteria() {

        return (String)ensureVariableManager().getVariableValue("SearchCriteria");

    }

    /**
     * Sets value for variable SearchCriteria.
     * @param value value to bind as SearchCriteria
     */
    public void setSearchCriteria(String value) {

        ensureVariableManager().setVariableValue("SearchCriteria", value);

    }

Select and sattle right the  setSearchCriteria from Client Interface of View Object.
