First Steps with SAP River RDE

DevWorkbench    Freitag, der 22. August 2014   

As promised, today we’re going to look at SAPUI5 application development with SAP River RDE, and we will take out first steps towards building a multi-million-dollar app. But before we can do that, we need to learn the basics.

Registering for SAP River RDE

Before you can register as a test user for SAP River RDE, you need access to the SAP HANA Cloud. This can either be your personal test account (you can register anytime you like, I’ve written a post about SAP HCP already), or your company’s account. Whichever way, you need to open your cloud cockpit and change to the Subscriptions tab. Click New Subscription to be presented with this popup, where you have to select rde.

After you’ve done that, rde will show up as a subscription in your account cockpit. To open it SAP River RDE, click on it in the list of subscriptions, and click again on the application URL that is shown to you in the next screen. You should now be taken to the SAP River RDE interface.


SAP River RDE User Interface

Creating your first project

After you’ve looked around the user interface a bit, it’s time to create your first project. To do that, right-click the Local folder and select New > Project from the context menu. Enter a project name and select the Empry SAPUI5 Desktop App Project template. This will generate the app descriptor as well as a controller and an XML view for you to start from.

Remember we’re building a SAPUI5 application on SAP River RDE. Don’t get confused with the names or the landscape – it’s a bit hard to maintain the overview at the beginning, especially of you’re new to both SAP River RDE and SAPUI5. Theres very good SAP documentation on River RDE as well as documentation on SAPUI5.

As our first project, all we want to do is to add some text and a link to the view file of your project. Open the view file that was generated for you – in my case it’s called main.view.xml. You want to add these lines of code to your view.

<mvc:View xmlns:core="sap.ui.core"
 <html:h1>Welcome to SAP River RDE!</html:h1>
  This is a paragraph in an XML view of SAPUI5.
  The elements are different from HTML5!
  <html:a href="">
   Go to dev-workbench

Notice that the individual elements are not XHTML or HTML5! They are dedicated XML elements that come from the SAPUI5 interface definition. Consult the API documentation to find out more about the available elements – there’s a lot of pre-built stuff, so you don’t have to invent everything from scratch.

After you’ve finished your view, the next step is to test your SAPUI5 application.
