Just back from Prometric, passed the 288 exam with 68% Preparation time was of two weeks, 2 hours per day. Percentage: Architecture and Core Concepts - 62% Develop Web Services - 71% Access Web Services - 60% Package, Deploy, and Publish - 62% Testing and Validation - 50% Security - 66% Web Services and Java - 100%
Just used the redbook of WebServices, but the other resources indicated in the certification site seems to be of great value. On my personal view, you only need to read chapters 1 to 6, 11, 13 to 16 and 20. A Lot of questions about the use of WSAD Wizards, Web Services Explorer and UTC, some SOAP and WSDL, ugly questions about UDDI , tons of JAX-RPC and one about projects for Java Sources That is all Folks. Next target is WAS 252, and submit my Part II assignament of SCEA.
