Hiya everyone,

I have a question from the OCA study guide, chapter 5 question 15:

Which of the following is true about concrete subclass?
b. A concrete subclass must implement all inherited abstract methods.
c. A concrete subclass must implement all methods defined in an inherited interface.


I don't understand why option B is correct whilst C is incorrect. According to the book option C is incorrect because a superclass could have implemented the methods. But wouldn't the same also apply to option B? All methods in interfaces are abstract and they can could be implemented by the superclass (whether concrete or even abstract) rather than the subclass. Would someone be able to explain this one?


Thanks.

Hi guys,

I am new to OSGi and I am having some troubles getting the Spring Web MVC framework working with OSGi.

A few questions:
- Firstly I assume I should be using Eclipse Gemini Blueprint and NOT Eclipse Equinox?

- Since Spring MVC uses a front controller/servlet, Dispatcher, I cannot seem to find an appropriate class for this. Spring DM used a different different class for the Dispatcher, since the original class did not support the OSGi framework. Any suggestions on what this class should should be?

- Do I need an Activator class? Some websites suggests I do not in this architecture, but they all seem out of date supporting Spring DM.

- Lastly, is there any up to date tutorials for using Spring Web MVC with OSGi? I can only seem to find tutorials based on Spring DM which is no longer supported.

Thanks in advance!





Hi guys,

Im not sure if this is the right place, but it seems to fit in here than anywhere else.

Anyway, my question is what is viewModel?? It quite confusing, I would just like to confirm my understanding of it. Is it the layer that converts the Model from one format or object into another for the View to render?

Edit: sorry I meant viewModel and not model view.


Thanks in advance.

Hi

I was wondering are there any popular tools that is useful in creating a java source code generation tool based on templates?

Also, since I am new to this, is there any tutorials or articles on the web about generating the business logic? As of right now, I cannot see how you could generate business logic code, but I know its related to Model driven architecture.

Thanks.

Hi

I was wondering is there anything equivalent of partial views in ASP.NET in Spring MVC?? A partial view is where only a part of the page gets updated, I assume using Ajax?

Thanks.

I actucally just figured it out a few minutes ago haha. I placed them in a new folder under WebContent. Thanks for the reply though.

Hi

I am trying to create a web application using the Spring MVC framework, but I am not sure where Javascript files go within the folder structure. Does it go within the WEB-INF folder or else where??

Thanks!
