Preparation for the RHCJD exam
Experience is the best preparation for Red Hat's performance-based exams. However, even experienced people sometimes have gaps in their knowledge, so Red Hat encourages all candidates for RHCJD to consider taking the JBoss Enterprise Application Development (JB225) course. This course is a good introduction to the topic and can help you prepare for the exam. Attendance in this class is not required, and one can choose to take just an exam. While attending Red Hat's classes can be an important part of your preparation, it does not guarantee success on the exam.
RHCJD exam environment
You will be working on a Red Hat Enterprise Linux® 6 system using JBoss Developer Studio 5 during the exam, so prior experience using Linux or UNIX is helpful, but not required. You will have a full desktop environment in which to work, and we will provide a list of basic commands for your reference in addition to the man pages and other documentation that come with Red Hat Enterprise Linux.
Audience
- Java™ EE application developers
