hi am in jdeveloper 11.1.1.9  I have a situation where I have to navigate to next page based on the condition how can I do that

this is what I have done so far

hi in my AppModuleTstImpl class the have this

    protected Object callStoredFunction(int sqlReturnType, String stmt, Object[] bindVars) {
            CallableStatement cst = null;
            try {
                //Creating sql statement
                cst = this.getDBTransaction().createCallableStatement("begin ? := " + stmt + ";end;", 0);
                //Register dataType for return value
                cst.registerOutParameter(1, sqlReturnType);
                //Pass input parameters value
                if (bindVars != null) {
                    //for (int z = 0; z < bindVars.length; z++) {
                    for (int z = 0; z < bindVars.length; z++){                                               
                        cst.setObject(z + 2, bindVars[z]);
                    }
                }
                cst.executeUpdate();
                //Finally get returned value
                return cst.getObject(1);
            } catch (SQLException e) {
                throw new JboException(e.getMessage());
            } finally {
                if (cst != null) {
                    try {
                        cst.close();
                    } catch (SQLException e) {
                        e.printStackTrace();
                    }
                }
            }
        }


public String getUsrStstus(String UsrId) {
            String UserSts = "No Status found";
            Object UsrStatus = callStoredFunction(Types.VARCHAR, "Cal.Usr_status(?)", new Object[] { UsrId });
            if (UsrStatus != null) {
                UserSts = UsrStatus.toString();
            }
            return UserSts;


       public String ExecUsrPswd(String SignId,String Spswd) {
        DBTransactionImpl dbti = (DBTransactionImpl)getDBTransaction();
        CallableStatement statement =
          dbti.createCallableStatement(("BEGIN "+"cal.Pswd(?,?);" +
                                        "END;"), 0);
        try {
            statement.setString(1,SignId);
            statement.setString(2,Spswd);
            statement.registerOutParameter(2, Types.VARCHAR);
            statement.execute();
            return statement.getString(2);
        } catch (SQLException sqlerr) {
            throw new JboException(sqlerr);
        } finally {
            try {
                if (statement != null) {
                    statement.close();
                }
            } catch (SQLException closeerr) {
                throw new JboException(closeerr);
            }
        }
    }
in my bean i have this

     public void PswdValidator(FacesContext facesContext, UIComponent uIComponent,
                                  Object object) {
          //   String msg =null;
                OperationBinding oBindings = getOperationBinding("ExecUsrPswd");calling a procedure
                OperationBinding oBindingsUsr = getOperationBinding("getUsrStstus");//calling a function
                oBindings.getParamsMap().put("signid",object); 
                oBindings.execute();
              
        Object o = oBindings.getResult(); //if the validation paase i what navigate to next inputtext and able to navigate to othe page
                                    //i what to call another screen if the function return status Open this screen is diffirent from the sccren if validation paased
        if(o != null) {
           String msg = o.toString();
                          FacesMessage fm = new FacesMessage(msg);
                          throw new ValidatorException(fm);

              }
                                  }

<af:inputText value="#{bindings.Password.inputValue}"
                                label="Password:"
                                columns="#{bindings.Password.hints.displayWidth}"
                                maximumLength="#{bindings.Password.hints.precision}"
