Hello there! I've just cleared part one (45/48 - 93%). As SCEA is an "old" technology speaking exam. I'd like to build my project based on new stuff like SOA. Am I free to use new stuff like Webservices, SDO, JBI & JPA?

I'm kinda confused on this. Also, am I free to choose the project subject?

Regards

Vinicius,

The project is given to you - no choice there. About the technology; as long as it's J2EE, it should be ok.

However, the assignment says:

Create a Component diagram that shows all of the J2EE components used in the system and their interaction. For example, what EJBs, Servlets, and/or JSPs might be needed?


So, it seems that these 'old' components are expected to be part of your solution.

Regards,
Dan

Hi Vinicius,

The subject assignment is defined from Sun Microsystems. When you do the assignment download, it is given you instructions about what should be produced and the nature of the assignment, which is, the use cases and scenarios itself.

In the given instructions, an small application is mensured to be designed, and the uses cases driven you about what to do.

Sun ask for j2ee as the main technology to be used, and you're free to use anything you want in the assignment, even you choose some cool and newly technologies as SOA or J2EE 5.0, you're free for that.

For example, in my assignment, I'd have to access an subsystem based on XML-RPC to validate and process a credit card. I have choose to use web services from my business tier.

If your assignment justify, you could use an ESB infrastructure to channel your incomming and outcomming services to integrate the application's subsystem's.

But don't worry, the technology choose is made by yourself!
