Hi, Nicholas,
Apart from web components and EJB, you need to have knowledge of
JDBC, JMS, JAAS, Connectors and JAXP for this exam.
You might pass the exam without this knowledge, but the score at least willn't be high.
Also, there's a great deal of architectural questions in the 484 exam, uniting different J2EE layers together. For my money, this is the hardest part of the
test.
You should be familiar with GoF and Core J2EE
patterns.
Hope this helps
