Sun Certified Java Developer (or SCJD) is the advanced Java programmer certification level. Unlike the easier SCJP, this level is intended to verify that the participant is able to write a real-world commercial application, solving all typical problems. It is the highest qualification that Sun confirms for the Standard Edition Java programmer.
The certification consists of the practical programming task and the subsequent written theory exam. The participant must write the described application, extensively using custom file formats, distributed computing (JRMP) and advanced Swing features that are not fully accessible from the popular rapid development tools (JTable, component data models and so on). The code must be documented, and the user manual must be supplied. The task itself is written in the form of a PRD for a non-programming end user. Apart from one or two interfaces, no technical details are given.
The participant is not allowed to use CORBA, RMI-IIOP, web browsers and third party libraries of any kind, because these might make a task too easy and are also subject of other certifications. He or she is allowed to use any preferred Java IDE. There is no strict time limit for this exam. A participant in this program is expected to spend several weeks writing the program. The main disadvantage of this certification is that the participant must invest the considerable amount of work (at least several weeks) in writing that program.
It takes up two months for the certification to be approved to allow time for the source code to be thoroughly examined.
