I have a struts based J2ee app which displays data from DB in the results.jsp page. For DB data access, I use a DAO which returns a serialized object. This serialized object, I set it to request object using setAttribute and retrieve it using <bean:write> tag i n jsp page.
 
My question is: if users try to open another window and do simultaneous tasks, how can I avoid same user from working in two or more different windows in a Struts based j2ee application ?
 
Any thoughts..
