#5 Restful Web Services Tutorial | Mock Repository

RESTful Web Services are basically REST Architecture based Web Services.
A REST API defines a set of functions to process requests and responses via HTTP protocol.
Rest is just a concept to use that we need an implementation.
To create an appliaction for REST you can use Maven Project with Jersey implementation.

In this video we will see how to
-Create separate class that returns data from database.
This class will create a list of object, and retun those list of objects
-Then we will fetch the result form our main class.

Trust me, I went through whole YouTube for web services tutorial and wasted my time. But, found the best content and explanation here. Thanks :)

[kamnijaiswal]

Hi Naveen! I really like the way you explain things, i knew nothing about REST earlier but after watching your videos i learnt some.But my query is - i tried to create a jersey project and i checked all 4 boxes as you mentioned in Preferences but still i am not getting any jersey archetype. Please let me know what can be the issue?? I kept it for whole night but still it did not loaded.

Congratulations, your example was the only one I did and it corresponded: theory and practice.
They were missing: example of request / response in JSON.
And examples with: @QueryParam and @PathParam

you created getAlien to get one alien object based on its ID. But you did not call it from your code

[MsWonderlands]

Yes I second Raju Siripuram.... Okay I tried calling that getALien from my Resource but how do we call individual/selective ids from the client? Please let me know. TIA

HI Naveen,
I have tried the same code that you have explained, but while trying to display the list I am getting 500-Internal Error.
Can you please give few possibilities why I am getting that error.
