1.Utility Classes should have constants for variable

public class PolicyUtils 
{
 public static final String TOTAL_POLICY_LIMIT = "totalpolicylimit";
 requestHelper.setRequestAttribute(TOTAL_POLICY_LIMIT, policyLimit);
}

Since multiple Users can access the JSP page at same time assigning variable name to constant and changing it later makes it easy to change the actual variable name in case needed in future.
