Hi Jayadev,
For 484 I used the following resources:
EJB - Mastering Enterprise
Java Beans - Ed Roman - 2ed
JAAS - "Java security, Part 2: Authentication
and authorization" found in DeveloperWorks
JAXP - "All about JAXP" and "JAXP revisited" from DeveloperWorks plus the JAXP 1.1 specification
JCA - "Introduction to the J2EE Connector
Architecture" - found in DeveloperWorks
JMS - "Introducing the Java Message Service" form DeveloperWorks and the "JMS Tutorial" form Sun
JNDI - Four part article from JavaWorld should be enough
JDBC - Sun Tutorial
JSP &
Servlets - Read some chapters from "SCWCD Exam Study Guide" just to refresh some points
By the time i took the exam (02/2004) I had enough time of experience in EJB, JAXP, JAAS, JDBC, JNDI, JSP and Servlets, so my study has focused in JCA and JMS, some quite new to me by that time.
Regards,
