Handling session in ADF application

Question

We're going to develop an application using ADF BC, JDev 11.1.1.2.0 and Weblogic 10.3. My idea is to put user specific information in a bean with session scope. I have couple of stored procedures to do some DML operations for user related data like profile, order information, etc. User logins first and multiple users may call the same procedure to insert or update or delete something. How ADF handles this scenario? Do I have to handle locking manually? If yes where and how? Thanks.

Hi,
ADF has the web session managed by the container. This means that a managed bean is available to the user for as long the session does not expiry (web.xml configuration) or is getting invalidated. ADF does nothing specifcally here
if you use prepared statements to access the database then locking is not automatically handled, same for releaing the database connect. You don''t give more hints in your question, so I can't give more information in my answer. Note that if you need to make resources or information available to all usres of an application, then application scope may be better to use than a session scope. E.g. the database access could be coded in a managed bean in application scope so that the acces is shared betwene users (just no user specific state should be saved in there)
