Hi, I have 5 years of experience in Java, EJB, JMS, JBoss AS etc . I have migrated JBoss 4.1 to JBoss 5 and experience in JBoss JMS server(HornetQ). Also experience in other JMS servers like ActiveMQ and Fiorano. It will take around 20 days becuase the some major changes are done in JBoss Microcontainer, JBoss Web, EJB3, JBoss Messaging etc. I can give you an exact delivery time once you give a high level view of the application. Looking forward to hearing from you.
Thanks
CRS
