IBM 287 & 484

Hi,
For these two exams, apart from knowing EJB, JSP & Servlets and studying Kushner's book, would you recommend any other book? If possible please list the materials one need to use for both the exams.
Do we know how long the voucher program will be available(is it open now?)?
Which of the exams is best taken first?
Do we need hands-on with Websphere or just the knowledge would be sufficient to answer the questions?
Thank you.

All the technologies, required in this tests are mentioned in the goals. So, for 484 apart from Servlets/JSP and EJB you need to know JMS, JDBC, JAAS, JAXP and Connector. You can use any books covering them.
I am going to take 484 first, then to play with Websphere and go for 287. For 484 you don't need the knowledge of WS.
The voucher program will be open till March but the number of vouchers is limited

There are still some though, I've received a one recently.

Thank you Serge for the info!
