I have created a login page in ADF and now my sir has asked me to maintain session for user such that if a user is already logged in and tries to login again from different tab or browser then he is prompted that u are already logged in / please logout before login. My sir told me that it requires minute changes in configuration file but i can't find any example on internet. Kindly help me with descriptive steps.
I am using JDeveloper 11g release 2
