I took the exam on September, 14th!!
Tips:
Book: Head First
EJB (read twice)
Mocks: from the HFEJB book and EJB Plus
Study an example of Deployment Descriptor:
http://www.valoxo.ch/jr/DeploymentDescriptor.pdf Read the EJB Spec chapter about "Portability: What
you should do to guarantee portability" (something like that)
