Calendar cal = Calendar.getInstance();

int month = cal.get(Calendar.MONTH) + 1;

initMaxCols();

return SUCCESS;

}

public String dateCellClick(){

return SUCCESS;

}

}

action配置：

HTML代码：

<%@ page language="java" contentType="text/html; charshttp://et=utf-8"

pageEncoding="utf-8"%>

<%

String path = request.getContextPath();

String basePath = request.getScheme() + "://"

+ request.getServerName() + ":" + request.getServerPort()

+ path;

%>

<%@taglib prefix="s" uri="/struts-tags"%>
