I have learned so much from you Koushik... Thank you! A suggested topic would be to cover securing the application/securing the REST methods.

Are the getters and setters used internally as well?? I forgot to add for the links in the code, it didn't show any error, but obviously, didn't show the links in the output as well.
Does Jersey call them during conversion?

Thanks for the awesome tutorial! What I dont get is why not add the links when you add messages, if we add links like this when we get one message, the links are not gonna show up when we try to get all messages. Anyone please lemme know.

why not just use getAbsolutePathBuilder()
instead of

hello what is the use of @xmltransient on comments list in message model. How do we use it ? It is clear that comments is a sub res of messages but how does it work ? I also found that you haven't declared comment model as @XmlRootElement

Hi i need help with jboss + oracle + simple call stored procedure web service or restful

[vipulthakur]

i didn't get the links as json response and there were couple of warnings too,
is it because of that or some other error

[geoffgriffiths]

I am getting a java.lang.ClassCastException:
java.util.ArrayList cannot be cast to ...model.Message

any ideas?

Great tutorials BTW.

[yingcai]

Is there any way to add the links without modifying the model classes ? What I mean is that in the case that we already have the model classes implemented and not editable for some reasons, is there a way to add the links in the response without changing the actual model classes ? 
BTW, great tutotial !

[ruixue]

1:56 The links could be sth like this ...
2:38 create a new model class called Link

[iandmetick]

you should publish a book for all topics of your tutorial.

[shivaprabhagar]

Hi Sir, the very good tutorial I ever seen, thank you very much, sir, if u have any Github link this source code, please provide this, thx again

Hi, I like your tutorials but you are teaching bad code practices.
For example, why should our MODEL Message contain Links, that are related to web part only. It required at least some decorator.
And a "helper" method in Message that takes 2 string args insted of Link. So, if iternal Link representation changes, we have to change Message class?

I understand that this is a tutorial on REST API, not design consepts, buy each time you do dirty :) things, you could just say: "I'm doing this just to be quick, but you shouldn't do this".

Anyway, thanks for your tutorials.
