Hello!
Yesterday I passed the SCJWD with 94%.
I will post some experience since there is not so many information available about the certificate.
Good books that I read were:
Sun Blue Prints Designing Webservices with
J2EE 1.4
And the RMH book.
Additionally I read the link about security from the Security Section of xyzws.com.
Then I read some articles about UDDI , SOA and Security from msdn.
This was all. But i made EJB Certificate and Web Certificate first so this knowledge was already in my mind.
There were only a few code samples and lots of architecture, so it
is rather concentrated on overall understanding
regards.
