Well the overall exam is not very difficult. Just follow the syllabus on SCJA and go through the basics on various java technologies as well. All the best

Well all the beta exams require you to wait for around 4-6 weeks before the results are released. But once SCJA is out of beta u will get the results immediately.

I took my SCJA today. You just have to follow the given objectives and I think you can do well on the exam. Parts of the exam that are difficult to me are the Server Side technologies since I don't have much experience on those. I think I did well on the Client Side. Some programming items are much difficult compare to SCJP. But in general, the language fundamentals is easy.

Tip: Study all the terminologies and the high-level description of the J2EE technologies.

Good luck to those who will take the exam.

God Bless,
Chris

No, result of beta exams will be announced 6-8 weeks after the beta exam concluded (i.e. 6-8 weeks after 15 July 2005).

Prometric will send you the score report via mail.

You need to identify the usage of them, for example, what is the usage of JNDI.

You also need to know the pros and cons of various technologies, like what are the advantages of RMI over sockets, or Swing over AWT. You need to have basic ideas on the mentioned technologies.

For RMI over sockets, I found the following pretty useful in this link...

RMI vs. Sockets and Object Serialization
The Remote Method Invocation (RMI) is a Java system that can be used to easily develop distributed object-based applications. RMI, which makes extensive use of object serialization, can be expressed by the following formula:

RMI = Sockets + Object Serialization + Some Utilities

The utilities are the rmi registry and the compiler to generate stubs and skeletons.

If you are familiar with RMI, you would know that developing distributed object-based applications in RMI is much simpler than using sockets. So why bother with sockets and object serialization then?

The advantages of RMI in comparison with sockets are:

Simplicity: RMI is much easier to work with than sockets
No protocol design: unlike sockets, when working with RMI there is no need to worry about designing a protocol between the client and server -- a process that is error-prone.
The simplicity of RMI, however, comes at the expense of the network. There is a communication overhead involved when using RMI and that is due to the RMI registry and client stubs or proxies that make remote invocations transparent. For each RMI remote object there is a need for a proxy, which slows the performance down.


And this for AWT versus Swing...

Hope these help...
