关于jsp分页问题

Question

不好意思，是这样的。直接把函数写在jsp页面里，然后调用。
public  void showcontent(int p){}
public void showpage(int totalnumber,int maxperpage,String filename){}这两个函数出错，出错信息

Answer 1

提示的是很清楚嘛
/bm_cqgd2006/jhgl_zhjh.jsp line 128有非法的表达式

Answer 2

就是调用两个函数出了问题，请问一下，jsp写函数是不是要用〈%！ %〉包起来。我没加！所以出现那些问题，但是包了之后也不行，请问我的两个函数这样写可以吗？<%!
