Hi Vaclav: Thanks for your reply.
HttpSession is a defined standard interface in JEE. The standard doesn't ask developers for explicitly calling HttpSession.setAttribute. The GAE/J provides a servlet container implementation which utilize datastore and memcache to store session data. It is supposed that the underlying implementation detail should be transparent to developers. The bottom line is that Google should document it clearly. But I didn't see any document about this issue. : ( -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
