Congratulation !

May I ask is the Upgrade Exam IZ0-805 only test those topics of new Java 7 ? or it is actually like the normal exam which test the entire topics just like the IZ0-804?

I am a Developer who have 3-4 year experience, I see problem on the software development process from initiation till release (e.g. business value of the software, quality of the developed product from user view and from developer view, etc.), and I am keen and have interest to gain knowledge/experience and improve the process and product.

I don't want to keep writing code just to fulfill requirements, I wish to do things which bring business value. (to avoid misunderstand, I didn't mean that coding doesn't bring business value)

Does all this related to Project Consultant / Project Coordinator ? How to move into this kind of Role ?

Thanks !!

Well, not sure what is your expectation on the answer for this question ...

For JDBC,
- security: SQL Injection (solution: PreparedStatement)
- performance/resource: connection/resultset/statement not close properly (solution: properly close in multiple finally{} of exception handling for each closing)
- design: repeating code (solution: Template Design Pattern, or use Spring JDBC Template)

... etc.

For Servlet/JSP,
- design: abuse MVC (solution: use framework, e.g. Struts ... but still able to abuse by sucks developer)

... etc.

Thanks for reply.

Realize that they are using C related programming if not wrong.

Well, so for those Enterprise Level Application, the most valuable application to be embarked on is SAP ? Any others ?

I have 3 years of Java/J2EE Development experience, and have partial ACCA.

Will all this help me to move into JD Edwards related job ?

Anyone is currently working on JD Edwards related job give me some advice ?

Sorry, I can't do that ... may improve interview skills to ask and make sure you get what you want.

(A)Suppose your question is about Java Interface:
thus,
1) you have many subclasses that implement the Java Interface provided in jar file
2) you are using coding to interface (e.g. InterfaceABC abc = new ClassMyImpl(); )
3) so polymorphism happening around all your client code


Suppose some x only change the Java Interface name , and method name left unchanged
Old Java Interface name: InterfaceABC
so your implementation classes name: ClassMyImpl implements InterfaceABC

now some x change the Interface name to: InterfaceXYZ

you create a new Interface with name: InterfaceABC extends InterfaceXYZ
you don't need to change your implementation classes name and all the client code that using polymorphism.
(BUT this will break polymorphism which calling method of implementation classes in jar file, because different class hierarchy)



(B)Suppose your question is about interface (means method definition) instead of the Java Interface:
Solution: use Design Pattern "Adapter Pattern"

Now started to create a checklist of what I can accept and what I can't for my next job search, and reading this book "Land the Tech Job You Love" ... learn from mistake

When they first come to interview, don discuss about the job scope first, give a test paper for them to work on it

1) if your company software is already up there and just need a programmer to write Java code to change some Change Request
and your company just need Java programmer who don't know Object-Oriented and code like a C programmer
a) a question on simple logic ( for...loop, if...else, switch...case, etc.)
b) give a Class with static and non-static method, ask them to write their own class to call the method

2) if your company software development follows good practice, design pattern, architecture, layering
a) prepare MCQ which similar to those SCJP , and only test those question related to what your company need
b) get a technical strong staff to interview that guy on all those concept (and HOW did they use it practically in past experience)

... what I am trying to say is ask and test them on what your company WANT and NEED

I have go through companies which give those MCQ test up to SCJP standard, test OO concept, and talk about MVC, multi-tier, layering ... but end up their code using Map/Vector as a Class to store attribute and value (argue that it is for flexible), getting to see presentation layer code call stored procedure directly, business logic in controller .... So, if your company doing all those things (which I don't want to argue whether it is right or wrong), you need to discuss all this with the candidate, and find out whether they feel that they are suitable for this ... but not trying to hide it.

Similar situation, anyway team lead told me just follow as is every time I raise a question, because decision is from management level. For example, prepare Detailed Design Documentation by changing code into pseudo code.

Good Luck

Thanks for your wishes.

But I have no idea to carry out the transition. Is it that difficult for a Developer to transit to other career ?
