BEA 8.1
Certified Developer: Build Solutions
Examination
Study
Guide
The BEA 8.1 Certified Developer: Build Solutions examination is designed to assess the critical areas of knowledge needed to successfully build custom solutions using BEA technologies, especially Workshop and Server, but also Integration and Portal.
The skills and knowledge certified by the examination represent a professional level of expertise at which a certified individual can:
§ Effectively perform the key job tasks required of their job role, using BEA WebLogic Platform 8.1
§ Apply a sophisticated knowledge of application servers with J2EE programming
§ Apply key concepts and implement best practices that are optimal for creating custom Web applications
The examination is designed to assess real-world job functions. To ensure the validity of the certification exams, a thorough exam-development process was conducted.
This examination concentrates mainly on Workshop-based development. Although some fundamental J2EE concepts and APIs are tested in this examination, it would be more accurate to view all questions as deriving from the use of Workshop to develop applications specifically for the WebLogic platform. Although the examination covers more than Workshop alone, no preparation will prove more helpful than using and studying Workshop extensively.
The BEA 8.1 Certified Developer:
Build Solutions examination is targeted towards developers with six to
twe
Number of Questions: 69
Time Allowed: 120 minutes, maximum

BEA recommends preparing for the certification exams by attending education training courses, reviewing on-line documentation and getting hands-on, real-world experience. Appropriate courses and documentation references are listed.
Course attendance is not required for attaining certification; however, it is strongly recommended, as training is the shortest path to competency. Industry studies show that a combination of training course attendance and self-study maximizes the likelihood of passing a certification exam on the first attempt.
Summary of recommended training courses:
