J2EE Web application
Posted on 2010-08-24
I have an existing web application writen in JSP/JAVA running under JBOSS server. Since many users access the application, a session is generated after user logs into the application.
I would like to replace this existing web application with a brand new application to be written in JSF/Spring running under JBOSS server. Since the applicatin is large, the application under new tech. stack will be completed over some period of time but I would like the end-users to be able to use the transactions in new application i.e. use new application for the transactions that have been completed but use the existing application for whatever hasn't been completed. Both applications (existing and the new) require log in and session will be generated after successful login.
I want to know whether it is plausible/feasible? How will the two application be able to share the transactional information? If the user is logged into one application and the transaction being processed needs to go to the other applicatoin, how will this happen or can it happen?
