JasperException:NullPointerException StringUtil BaseTag


出现个问题：用户免登陆访问的页面，会报这个错，但如果用户登录了网站，session中有用户时，此session 下打开的页面就正常。
求教各位大咖！！！

问题：lanCode为空，应该是js插件适用XX-en.js还是XXX-zh-cn.js的后缀叫langCode.
解决方法一：不要调用<t:base 标题来加载
<%--<t:base type="jquery,easyui,tools,DatePicker"></t:base>--%>
解决方法二：
在具体页面调用的方法的HttpServletRequest的参数里里加“lang”值
req.getSession().setAttribute("lang","zh-cn");//HttpServletRequest req或request
