  public static Integer getStock(String strdate, Long orgId, Long productId){

  if(strdate==null||orgId==null||productId==null)

  throw new IllegalArgumentException();

  Integer stock = null;

  //DataAccess da = DataAccessFactory.create(BPMConstant.ERP_DATABASE);

  Connection conn=null;

  CallableStatement fun = null;

  try {

  String callSQL = "{?=call getstock(?,?,?)} ";

  //Connection conn = da.getConnection();

  conn=DBUtil.getConnection(BPMConstant.ERP_DATABASE);

  fun = conn.prepareCall(callSQL);

  fun.registerOutParameter(1, oracle.jdbc.OracleTypes.NUMBER);

  fun.setString(2, strdate);

  fun.setLong(3, orgId);

  fun.setLong(4, productId);

  fun.execute();

  stock = fun.getInt(1);

  }catch(Exception e){

  e.printStackTrace();

  }finally{

  DBUtil.closeCallableStatement(fun);

  DBUtil.closeConnection(conn);
