在JSP页面里,能点出来,运行的时候报错,在.java文件里能运行
An error occurred at line: 43 in the jsp file: /userInfo.jsp
The method getUserPageBySel(String, String, int, int) is undefined for the type CustomerDaoImpl
40: List<Customer> list = null;
41:
42: if(whe == null)
43: list = cusImpl.getUserPageBySel("allUsers", "", 3, 1);
怎么解决啊?
