We are using Jboss 3.2.7 with multiple projects deployed on jboss server.
Recently we have started getting more and more session log out instances from client side.This generally happen while we do export process from client side which are heavy processes and take around 10-15 min to complete.
We have checked the HttpSessionTimeout setup in JBoss at following location:
1) default timeout value for every web application : deploy/jbossweb-tomcat55.sar/conf/web.xml is set to 30 min.
2) To override the default HttpSession timeout on a per-webapp basis we have entries in defined it in every project WEB-INF/web.xml , which is also set to 30 min.
3) Also checked that we are not setting HttpSession.setMaxInactiveInterval(int seconds) in code manually.
In-spite of 30 min timeout defined in for syetem, we are facing session log out problem frequently.
Need help in rectifying this problem with solution.
