In my jsp page some pure java code there i.e, scriptlet. After a long time when refresh it then it is throwing
org.apache.jasper.JasperException: java.lang.NullPointerException
sometimes not for a long time also it is throwing same Exception. and the JSP page is displaying empty page. So the user have only one option is Logout. So to avoid that and redirect him to one page that is error page. How to do it??
Any idea???
