  • SAP introduced an HTML5-based development toolkit, SAPUI5, which encourages one consistent user experience.
  • Apps built using SAPUI5 are responsive across browsers and devices – they run on smartphones, tablets, and desktops.
  • UI5 is a client UI technology based on JavaScript, CSS and HTML5.
  • Servers come into play for deploying your applications, storing the SAPUI5 libraries, and connecting to a database.
  • SAPUI5 supports the Model View Controller (MVC) concept.
    • Model: This is responsible for managing the application data in the database/backend.
    • View: This is responsible for defining the user interface to users. When a user sends a requests from his device, the view is responsible for data view as per the request submitted.
    • Controller: is used to control the data and view events as per user interaction by updating the view and model.
  • In this blog, we see, how we can create a UI5 application project and its contents.
  • This blog is part of below parent blog:


  • Eclipse having SAP UI5 Development Tool kit
    • For e.g. Eclipse Juno Service Release 2
    • To make it compatible with SAP UI5 App follow below steps:
      • Open Eclipse -> go to Menu item ‘Help’ -> ‘Install New Software’ -> type url
      • Select ‘UI Development Toolkit for HTML5’ -> install
    • Or refer below link:
  • SAP/Non-SAP’s data access medium
    • For e.g. In case of SAP, we require RFC
    • And in case of Non-SAP, web-service or other medium

Steps to create a UI5 application in Eclipse

In this SAP-UI5 application example, data is referred from a ‘JSON model file’

  1. Open Eclipse -> go to Menu ‘File’ -> select ‘New’ -> ‘other’
  2. In New Wizard pop-up, select ‘SAPUI5 Application Development’ -> ‘Application Project’ ->click on button ‘Next’
  3. Enter Project name -> select Target device as ‘Mobile’ -> select ‘create initial view’  its optional, it well create view on page -> click button ‘Next’
  4. Enter view name -> here select Development Paradigm as ‘Xml’
    • Here page view control will be defined in ‘Xml’
    • and its controller logic will be handled in JavaScript page
    • click button ‘Finish’ Button
  5. Once project gets created, we can see it in left panel explorer
  6. Here, we will re-structure created SAPUI5 project by adding few new folders/files/views under ‘WebContent’ as below,
    • When we run this UI5-App in Eclipse, its flow is as below:
      • ‘index.html’ -> ‘Component.js’ -> ‘App’ view -> ‘Master’ view -> ‘Details’ view
    • Post-deployment of this UI5-App in SAP-Fiori (Front-End) server, its flow is as below:
      • ‘Component.js’ -> ‘App’ view -> ‘Master’ view -> ‘Details’ view
    • Post creation of this UI5-App, we deploy all files/folders of ‘WebContent’ folder
  7. Details of SAPUI5 Application Project Structure:

    1. The WebContent folder contains all the folders, including Component-preload.js, Component.js, index.html, view, model, css, i18n etc..
    2. The CSS folder, which include customizing the sap ui5 application. Add any css files in this folder.
      • /* Make Text Bold */
        	font-weight: bold;
            font-size: small;
            color: red;
    3. Next is the i18n folder, which is used for Globalization purpose. It includes i18n files for particular languages.
    4. model folder consists of the local data for testing ‘sampleData.json’ file.
      • {
          "listItems" : [
              "title" : "Sales Reports",
              "MATNR" : "000000000000202031",
               "info" : "Overdue"  
              "title" : "Purchase Reports",
              "MATNR" : "000000000000202033",
              "info" : "Overdue",
              "infoState" : "Error"
              "title" : "Financial Reports",
              "MATNR" : "000000000000202036",
              "info" : "4 day ago"
    5. view -> utils folder consists the ‘connectivity.js’ file, it is used to store OdataService path details.
      • var hostPort = "";
        // this setting is required to test app with odataService in Eclipse environment
        //hostPort	 = "proxy/http/<host>:<port>";
        //Odata Service Path
        var oDataPath = "/sap/opu/odata/sap/ZTEST_ODATA_SRV/";
        // Odata Service Url
        var serviceUrl= hostPort + oDataPath;
    6. Component-preload.js file is mainly used for optimization purpose.
    7. Index.html file serves the same purpose here, we declare the shell  here. And all the library files are loaded in index.html, it also calls ‘Component.js’
      • <!DOCTYPE HTML>
        		<meta http-equiv="X-UA-Compatible" content="IE=edge">
        		<meta http-equiv='Content-Type' content='text/html;charset=UTF-8'/>
        			data-sap-ui-libs="sap.m, sap.ui.layout"
        				"ZTEST_APP": "./"
        			}' >
                        <!-- Calling Componet-name of Component.js of UI5 -->   
        			new sap.m.Shell({
        				app : new sap.ui.core.ComponentContainer({
        					name : "ZTEST_APP"
        	<body class="sapUiBody" id="content">
    8. Component.js file is used here for declaring the models, (odata, json, or i18n). Moreover, here the router initialization is also done.
        sap.ui.core.UIComponent.extend("ZTEST_APP.Component", {
        	metadata : {
                stereotype 	: "component", 
                "abstract"	: true,  
                version 	: "1.0",   
                library 	: "ZTEST_APP", 	         //required for CSS reference
                includes	: [ "css/Styles.css" ],  //CSS style reference     
                dependencies: { 			 //external dependencies
                    libs 	: ["sap.m", 
                         	   "sap.ui.layout" ], 	//the libraries that component will be using            
                    library	: "sap.ui.core",	//what library belongs your component to              
        	createContent : function() {
        		// create root view
        		var oView = sap.ui.view({
        			id 		: "app",
        			viewName 	: "ZTEST_APP.view.App",
        			type 		: "JS",
        			viewData 	: { component : this }
        		// set device model
        		var deviceModel = new sap.ui.model.json.JSONModel({
        			isPhone 	:,
        			listMode 	: ( ? "None" 	: "SingleSelectMaster",
        			listItemType: ( ? "Active" 	: "Inactive"
        		oView.setModel(deviceModel, "device");
        		// done
        		return oView;
      • As we can see, this Component.js file has created/referred App view in “createContent” function.
    9. The view folder, which the views, both xml & javascript files.
    10. Example:
      • In this UI5 App example, application will have a main page which includes two buttons and one list control.
      • On click of 1st button, list get filled with model/sapleData.json details
      • On click of 2nd button, navigation to 2nd page (Details)  is been done from 1st Main (Master) page
      • From 2nd page, back navigation to 1st page is also handled.
      • Following are the details of each page
    11. View ‘App’
      • Here ‘Development Paradigm‘ is JavaScript that means both view and controller are in javascript
      • View: ‘App.view.js’
      • Here, we can see in code, ‘Master’ view has been loaded & Empty page reference has been given.
      • sap.ui.jsview("ZTEST_APP.view.App", {
        	getControllerName: function () {
        		return "ZTEST_APP.view.App";
        	createContent: function (oController) {
        		// to avoid scroll bars on desktop the root view must be set to block display
        		// create app
 = new sap.m.SplitApp();
        		// load the master page
        		var master = sap.ui.xmlview("Master", "ZTEST_APP.view.Master");
        		master.getController().nav = this.getController();
, true);
        		// load the empty page
        		var empty = sap.ui.xmlview("Empty", "ZTEST_APP.view.Empty");
, false);
      • Controller: ‘App.controller.js’
      • Here, two navigation functions are been defined,
        • to() function for Next page navigation
        • back() function is for back page navigation
      • sap.ui.controller("ZTEST_APP.view.App", {				
        	 * Navigates to another page
        	 * @param {string} pageId The id of the next page
        	 * @param {sap.ui.model.Context} context The data context to be applied to the next page (optional)
        	to : function (pageId, context) {
        		var app = this.getView().app;
        		// load page on demand
        		var master = ("Master" === pageId);
        		if (app.getPage(pageId, master) === null) {
        			var page = sap.ui.view({
        				id 		: pageId,
        				viewName: "ZTEST_APP.view." + pageId,
        				type 	: "XML"
        			page.getController().nav = this;
        			app.addPage(page, master);
 "app controller > loaded page: " + pageId);
        		// show the page
        		// set data context on the page
        		if (context) {
        			var page = app.getPage(pageId);
        	 * Navigates back to a previous page
        	 * @param {string} pageId The id of the next page
        	back : function (pageId) {
    12. View ‘Empty’
      • This is xml view, which will be used only in Desktop Mode to overlap ‘Details’ page while navigating back to ‘Master’ page
      • View: ‘Empty.view.xml
      • <core:View
        	xmlns:core="sap.ui.core" >
    13. View ‘Master’
      • Here we create Two button and one List control
      • Button ‘GetMaterial’:  on click of this button fill List control with sampleData.json items
      • Button ‘NextPage’: on click of this button, navigate to ‘Details’ view
      • List control: where items will be filled on button ‘GetMaterial’ event
      • View: ‘Master.view.xml’
      • <core:View xmlns:core="sap.ui.core" xmlns:mvc="sap.ui.core.mvc"
        	xmlns="sap.m" controllerName="ZTEST_APP.view.Master" xmlns:html="">
        	<Page title="App Example">
        					<Button text="GetMaterial" press="pressGetMaterial" type="Accept" />
        					<Button text="NextPage" press="pressNextPage" type="Emphasized" />
        			<List id="idList1" mode="{device>/listMode}" items="{/listItems}">
        				<StandardListItem title="{MATNR}" />
      • Controller: ‘Master.controller.js’
      • here we can see three functions:
        1. pressNextPage():  which will be invoked on press event of button ‘NextPage’, to navigate to “Details” view
        2. pressGetMaterial():  which will be invoked on press event of button ‘GetMaterial’, to fill list control with data
        3. call_MoldeFile(): which will be invoked from function pressGetMaterial(),  to read ‘sampleData.json’ file and fill fill list control with data
        sap.ui.controller("ZTEST_APP.view.Master", {
        	pressNextPage: function(evt) {	
                        //Navigation to detail page
        		var context = evt.getSource().getBindingContext();
"Details", context);    //to() is defined in 'App.controller.js'
        	pressGetMaterial : function(evt) {
        	call_ModelFile: function(){		
                        //Calling model json file for data reference
        		var sample = $.sap.getModulePath("ZTEST_APP", "/model/sampleData.json");
        		var oModel = new sap.ui.model.json.JSONModel(sample);
        		//Set JSONModeloutput to ListControl
        		var list = this.getView().byId("idList1");
    14. View ‘Details’
      • Here Navigation is shown.
      • Back navigation button will take to 1st page, and in case of desktop mode, Center page gets overlapped with ‘Empty’ view
      • View: ‘Details.view.xml’
      • <core:View xmlns:core="sap.ui.core" xmlns:mvc="sap.ui.core.mvc"
        	xmlns="sap.m" controllerName="ZTEST_APP.view.Details" xmlns:html="">
        	<Page title="Detail Page" showNavButton="true" navButtonPress="backPress">
        			<Label text="Welcome to Detail Page !!" design="Bold" />
      • Controller: ‘Details.controller.js’ 
      • This has on back navigation function event backPress(), which will be invoked on press button of ‘back’ icon in ‘Details’ page
      • sap.ui.controller("ZTEST_APP.view.Details", {
        	backPress : function (event) {
        		var context = event.getSource().getBindingContext();
        		if (!{
        			this.nav.back("Empty", context);
        		this.nav.back("Master", context);
  8. Testing of SAPUI5 app in Eclipse

    • To test UI5 application in eclipse, in left pane project -> select ‘index.html’ -> right click -> ‘Run As’ -> ‘Web App Preview ‘
    • Next ‘Index.html opened as below screen
    • Perform button event like ‘GetMaterial’ and ‘NextPage’ to see the results
  9. Thus we have created one UI5 application sample which is accessing data from model json file enclosed within project itself.

    Dear Dilip

    Your series blogs are instrumental for beginners, very useful and informative.

    I habituated to develop UI using drag and drop in webdynpro Java and ABAP,  in fact it was developer friendly. I feel managing  MVC using the core code is a bit tough job now, are there any tools to develop UI5  apps using drag and drop features.



  2. Naoto Amari

    Hello! readind deeper i found your courses ! is any problem if i use eclipe oxygen ? it’s ok if i create the folder utils in the same level as  model ???

    1. Dilip Kumar KrishnaDev Pandey Post author

      Dear Naoto,

      Sorry for delayed response, I was too much busy in my current project….

      1. I have not used eclipe oxygen for Fiori App till now. I can only ensure you for eclipse-Juno/Mars/Neon which I’ve used while app development.
      2. You can create utils folder in same level as model, and then while referring in .js pages, please change respective paths too like as below:
        • instead of
      3. For 2nd point, I recommend you to follow view/utils only


      Thanks & Regards

    Hi Dilip, I have any problem with testing this app. – step 8

    HTTP ERROR 404

    Problem accessing /ZTEST_APP/WEB-INF/index.html. Reason:

        Not Found

    Can you help me?

    I am beginner with eclipse and FIORI, sorry…

    Thanks Tomas M.

      Dear Tomas,

      Sorry for delayed response, I was too much busy in my current project….

      Please correct your Fiori App Project Structure, it should be like below:

      i.e. index.html never resides in WEB-IN

      Thanks & Regards

    Hi Dilip, many thanks for your answer. I corrected my project structure and working fine, but… I created, registered and activated OData service in SAP. I try tested with TCODE /n/iwfnd/gw_client and I think that is OK. But from Eclipse I see problem:

    Can you help me again? Problem with user and password? Thanks from Czech Rep. TomasM

    1. Dilip Kumar KrishnaDeo Pandey Post author

      Dear Former Member,

      While accessing from Eclipse, give below prefix , that will resolve Cross domain issue.

      • proxy/http/<host>:<port>/<ui5 path>
      • instead of current path

      But do not forget to remove prefix while uploading app in Fiori server.

      Thanks and Regards



  5. Nelson Kharat

    Hi Dilip,

    Very nice blog.

    I could not find the file Component-preload.js in the project and it is stating 400 error when debugged with F12.

    Please let me the know the code to be added into the file.


    1. Dilip Kumar KrishnaDeo Pandey Post author

      Hi Nelson,

      Thanks for the comments.

      About ” Component-preload.js “, this we basically to improve runtime performance and to modularize UI5 App’s code/functions.

      As above was a basic test app example, so I haven’t used it but kept it blank to avoid 404 (not found) error found during debug.

      Regarding same nice explanation can be found from below blog by Mr. HP Seitz


      Thanks & Regards,
