Error in Unique Bill Number alg using SDK

Question

Hi friends,
I am trying to generate unique bill no by taking InstallationDocumentNumberAlgorithmSpot i added pluged this algorithm (admin->installation options framework)
But i am getting some error ,pls help me how to solve this.
public class CMBillNumber_Impl extends CMBillNumber_Gen implements
          InstallationDocumentNumberAlgorithmSpot {
     private static final Logger logger = Logger
     .getLogger(CMBillNumber_Impl.class);
     private Bill bill;
     private String docNumber;
     @Override
     public void invoke() {
          validateInput();
          Premise prem = bill.getAccount().fetchMailingPremise();
          Premise_Id premise_Id = prem.getId();
          GeographicType_Id geotype = new GeographicType_Id("SECTION");
          Query query = createQuery("from PremiseGeographicLocation pgl where pgl.premise.id= :premiseid and pgl.geographicType=:pgeocd ");
          query.bindId("premiseid", premise_Id);
          logger.warn("Premise id Number is "+premise_Id);
          query.bindId("pgeocd", geotype);
          query.addResult("geographicValue", "pgl.geographicValue");
          logger.warn("Premise id Geo is "+geotype);
          Iterator it= query.iterate();
          String sectionValue = "";
          while(it.hasNext())
               sectionValue=it.next().toString();
          // PremiseGeographicLocation PrGeo=
          // pr.getGeographicLocations()pr.getCharacteristics().
          docNumber= sectionValue+"12345";
          logger.warn("Bill Number is "+docNumber);
          // TODO Auto-generated method stub
     private void validateInput() {
          if (this.bill == null) {
               logger.warn("this.bill is nill");
               addError(com.splwg.base.domain.StandardMessages
                         .fieldMissing("BILL_ID"));
     @Override
     public String getDocumentNumber() {
          // TODO Auto-generated method stub
          return docNumber;
     @Override
     public DocumentTypeLookup getDocumentType() {
          // TODO Auto-generated method stub
          return null;
     @Override
     public void setBill(Bill bill) {
          this.bill = bill;
          // TODO Auto-generated method stub
     @Override
     public void setPaymentEvent(PaymentEvent arg0) {
