Highlight the currently selected row with a different color in ADF table

The following styleClass EL expression would achieve the required functionality

<af:table value="#{bindings.EmployeeDetailsVO.collectionModel}"
          var="row" rows="#{bindings.EmployeeDetailsVO.rangeSize}"
          styleClass=#{row.row ==  bindings.EmployeeDetailsVO.currentRow ? 'background-color:Green;' : 'default'}
          emptyText="#{bindings.EmployeeDetailsVO.viewable ? 'No results'  : ' Denied.'}"
          fetchSize="#{bindings.EmployeeDetailsVO.rangeSize}" rowSelection="single"
          rowBandingInterval="1" columnStretching="last" autoHeightRows="-1" id="t2"
          disableColumnReordering="true">

convert java.util.Calender to java.util.date

import java.text.SimpleDateFormat;

import java.util.Calendar;
import java.util.Date;

public class DateUtils {
    public static void main(String [] args) {
        Calendar cal = Calendar.getInstance();
        Date d =  cal.getTime();

        SimpleDateFormat sdf = new SimpleDateFormat("MMM dd, yyyy HH:mm aa");
        String documentDate = sdf.format(d);

        System.out.println(documentDate);
    }
}
