i have made a little webapp in Java using jsp and am having a little problem with Login Authentication..
i have 4 different users. have 4 tabs in a jsp page
i need to give them the limited access to Tabs.
eg-director (can see all the tabs) officer 1 (can see only have accesses to 3 of tabs ) officer 2 (can see only have accesses to 2 of tabs ) officer 3 (can see only have accesses to 1 of tabs )
it is like a security clearance i tried to so many ways and failed and i am thinking to do that with passing a Boolean to Database and give the access levels for that i need a help if it is with a small sample log in project that will be very help full for me

Try this way out,
After successful login, save user type in session. Then in jsp add following conditions for role.
let's say for example, We want to block access of Tab 4 for 'officer 2'.
Then in jsp for Tab 4 , add below condition. and like wise in other jsp's also.
<c:if test="${role== 'officer 2'}">
<jsp: forward page="../invalidAccess.html"/>
</c:if>
alternatively, You can make use of Filters to do same. Filters are more preferred over earlier way.
