General

Hi,
I am new backendless.
Where can i download sample ShoppingCartService.jar, i would like to decompile and use it to get started with my own API.
Specifically, I would like to know how to store/retrieve data from persistence storage.
Also , i would like to know how to make calls to external REST services from this service class.
HelloWorldService does not show much…
Can you please help?

Hi!

Go to Files page on Backendless console -> servercode folder -> you can download ShoppingCartService-src.zip.

Specifically, I would like to know how to store/retrieve data from persistence storage.
You can use our documentation http://backendless.com/documentation/data/rest/data_overview.htm.
Or use video tutorials https://www.youtube.com/user/Backendless/videos

Also , i would like to know how to make calls to external REST services from this service class.
I think it will help http://backendless.com/documentation/business-logic/java/bl_external_hosts.htm

Regards,
Kate.
