Can any one explain DAO design pattern with example? (please dont give me the urls by searching google)


What is the difference between giving a web (can be search by Google), and explaining here?
Just declare a parameter, Spring will bind a request to a command object automatically.
Read Javadoc for more details.

We aren't allowed to create a instance directly because the constructor is private or protected so we have to use a public static method to get the instance.
You have to be a project manager at least 3 years to be eligible to take the PMP exam.
MIDP 3 is released now. And Sun is updating certifications for Java EE 6.
Is there any news about the next version of SCMAD?

So what's your opinion about upgrade exams for JEE6, how will they parallel those exams with the newly introduced exams as you mentioned JSF,JPA 2.0


I don't know for sure. But I guess that:
- Next SCBCD will focus less on JPA and focus more on other features of EJB
- Next SCWCD will be updated to cover Servlet 3.0 and JSP 2.2/EL 2.0
- Next SCDJWS will cover JAX-RS
- Next SCEA Part 1 will cover the new specifications in Java EE 6
I have no idea about Telecommunication field certifications so I cannot give any suggestions.
Many thanks for the information.

Interesting. They separate JPA as a new certification, it's probably based on JPA 2.0 and the JSF certification is finally added.
Actually I hoped they to revise SCEA or introduce a more advanced level of SCEA, but it might not happen anytime soon .
You might be interested in Microsoft Certified Architect program.

Many people misunderstand Composition, the Composition concept is very important and it has nothing to do directly with memory management. Software is a model of real-world object, composition is the concept of real world that we're modeling.



Oh, I think we are in violent disagreement here!

Software is not a model of real world objects. Software is a model of the *solution* to a problem. And it needs to be a model that takes into account the forces of being implemented in a computer. As one consequence, this model will look significantly different based on, for example, the language used to describe the implementation.


You're right. My statement was misleading. Actually I didn't want to mean that software is a model of real world objects as they are. Because the problem is what is the true definition of real world objects? Different people will see the same thing differently. Modeling a real world object as it is (from the eyes of the modeler) in software or in any forms is narrow and limited.

It was misleading nevertheless. I should improve my communication skills . Thanks for pointing out.

Anyway, model of the solution is only a description from a single viewpoint. To me, as a DDD guy, software is also a model of "domain concepts" of the system.
