ABAP Mentor

Overview

In the last few lessons, we talked about the BSP application itself, the data retrieval in JSON, and how to handle URL parameters. Today, I want to give some help to the developers, who want to retrieve their data simply in XML. To achieve this, we are going to perform a few modifications only.

How to retrieve data in XML format

Overview

In the previous posts, we built a very simple BSP application that we used to retrieve a simple, hard-coded JSON. Then we went ahead, and we replaced this hard-coded JSON in code using a simple SELECT statement, and a JSON transformation.

Today, we move on and talk about how to pass parameters to our web service in order to pass a filtered data back to the client. We are going to solve these requirements using Page Attributes.

Overview

In the previous post, we built a very simple BSP application that we used to retrieve a simple, hard-coded JSON. Today, we go ahead, and talk about how we can produce this hard-coded JSON in code. In order to do this, I'm going to introduce you the Event Handlers in Pages with Flow Logic.

Overview

Today, I want to share a very handy approach with you about building simple web services in SAP. It's a lightweight alternative to the SOAP web services. I mostly try to avoid building SOAP web services, since they provide very thick interfaces, always need to regenerate the proxies and so on, so it can be a nightmare in complex cases (at least for me). I usually prefer building RESTful web services using the SAP Netweaver Gateway, but what if I don't have it?

To demonstrate the approach, we are going to build a simple web service that uses JSON format and deals with flight schedules.

Build native iOS, Android, and Windows apps using C#

Nowadays, our team is working on projects that deal with cross-platform native mobile developments both on iOS, Android, and Windows Phone. So, over the last couple of weeks, we spent our time in Xamarin Studio, but I didn't mind that, sometimes the changes are good. :)

This week I had to finish the communication bridge between Xamarin and our SAP BW system, so I build a SOAP proxy in Xamarin Studio based on the SOAP Endpoint that I created earlier. I was really surprised by the results, it was very easy. In this demo, I want to share you my experiences. Enjoy it!

Practical Guide for Developers

I am proud to announce that from now on I'm going to share my experiences, tips & tricks in this blog that I face during my work. Besides you can check my timelapse videos also that I create in my free time.

This video is the part of our recent Pluralsight course that is going to be published in July 2014. You can check our courses here:
