Finally, I passed the 158 test. The exam is realy very surpring. It is lengthy (every question) and more complicated than ICE test. WhizLab's mock exam only contributes a little to the final result. In my opinion, people should spent more time in IBM's Redbooks than in the designated reading materials. John Chien
SG 246176 - IBM Websphere V 4.0 Advanced Edition Handbook. SG 246124 - Programming J2EE APIs With Websphere Advanced. SG 246134 - Websphere version 4 Application Development Handbook. SG 246144 - EJB Developmentwith Visualage for Java for Websphere Application Server. You can purchase the mock exam from Whitzlab. However, their mock exam can only correct some of your basic concepts. Besides that, it is quite useless in term of taking 158. The real exam is much complicated than the mock exam. There are a lot of exhibits. Each question is lenghthy in comparison with ICE exam and mock exam. If you purchase the mock exam, you are wasting your money. Read the redbook, especially the SG246144. The indicated 3 exam preparation textbooks are not that helpful. I hope this will be of help to you.
