通过Kettle自定义jar包供javascript使用

public class PaginationUtils {

 /
   计算得到总页码
   @param totalRecords 总记录数
   @param pageSize 分页大小
   @return 总页码
  /
 public static int totalPage(String totalRecords,String pageSize){
  int totalPage=0;
  try{
   BigDecimal records=new BigDecimal(totalRecords);
   BigDecimal size=new BigDecimal(pageSize);
   BigDecimal _tmp=records.add(size).subtract(new BigDecimal(1));
   BigDecimal _tp=_tmp.divide(size).setScale(0,BigDecimal.ROUND_HALF_UP);
   totalPage=_tp.intValue();
  }catch (Exception e){
   //error
  }
  return totalPage;
 }
}

//计算总页码
var totalPage=.study.spring.Utils.PaginationUtils.totalPage(countBySql,pageSize);

不能编译 javascript: .mozilla.javascript.EcmaError: TypeError: Cannot call property totalPage in object [JavaPackage .study.spring.Utils.PaginationUtils]. It is not a function, it is "object". (<cmd>#22)
