Welcom to JavaRanch.

hi,
iam new to java,
iam not doing any authentication,
simply wrote html and jsp pages and all my coding is working.
for ex:http://localhost:2020/ukalthy/example/search2/adminindex.jsp
actually this page comes after successful login.
but by copying this url and paste in another webpage then also iam getting output as iam getting in previous senario.
how to solve this...

thanks,
kalthy

You should be checking for the authentication on every request using a filter, or configure container-managed authentication.
