Consuming REST webservice into SAPUI5 App.

May 05, 2017 at 10:45 AM | 453 Views

I am trying to consume REST Web service into my SAPUI5 Application.The webservice response is in JSON format. How do I bind the data coming in my application.

I get the Error : Failed to load resource: the server responded with a status of 404 (Not Found)

// The controller code is as follow :

onInit: function() {

$.ajax({

url: "http://localhost:8080/sdnext/doj/webservice/json/employees/",

type: "GET", dataType: "text",

contentType: "text/json",

success: function(data, textStatus, jqXHR) { response = data; },

error: function(xhr, status) { console.log("ERROR"); },

complete: function(xhr, status) {

var oModel = new sap.ui.model.json.JSONModel(); oModel.loadData(response); this.getView().setModel(oModel);

} });

View is in the image attached for data Binding.

    Hi Jun Wu,

    I am able to get the json data when I enter it in the browser. The webservice is working fine.

    I tried to make it work from my hana cloud web IDE but no luck there. Can you suggest any other way I can consume this web service into an SAPUI5 application? Maybe by Eclipse IDE ?

    regards,

    Sushil

      The REST web service I created and deployed it to my tomcat server , locally. (i.e localhost:xxxx). It is accessible when the tomcat server is on.

    Hello Sushil,

    Could you please show how you are binding your table. Also check in your network tab for the response. If response is coming then there is an issue with table Binding.

    Thanks,

    Vikash

      Hi Sushil,

      If in your employee json model data is coming then you will get the records in your table. Once you gets data from backend , set that data into json model and give a namespace employee.and then set the table with the jsonmodel.

      First requirement would be to get the data from the backend system.

      Thanks,
