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 ?
If your worry is that someone might submit changes to an object that has changed since the generation of the form (and therefore overwrite previous changes), maybe a simple solution would be a "version" column in your table, only persisting submitted changes where the version still matches what's in the DB.
You don't need to use hibernate to do this, but here's their take on this: http://www.hibernate.org/hib_docs/v3/reference/en/html/mapping.html#mapping-declaration-version
