Consume Odata Service in Eclipse HTML5

Hi Experts,
     I am trying to consume SAP Odata service. But i was stuck in one problem. While creating my model object i got following message.
This code i have written in the index.html file.
var oModel = new sap.ui.model.odata.ODataModel("",false, "[username]","[password]" );
when i trying to directly execute the same service using Google chrome it gives me data. But if the same service i was trying using the eclipse i got this message. Can u please tell how to create object for the oModel or is there any other thing  that i have missed, One thing i was noticed here that automatically $metadata is appended in the service while calling and how we can overcome this problem.
OPTIONS$metadata  datajs.js:17
(anonymous function)index.html:22
Please help me how to solve this problem. Initially, i am just trying to create the model object.

Hi Nishant,
If you are unambe to access your service from Eclipse, we need to check few point from Gateway developer.

  • Consume OData service in SUP 2.1.3

    How to consume of OData service in SUP 2.1.3 for creating MBO for HWC?
    Our OData service is having mandatory filters which needs to be passed.
    http://xxx:8000/sap/opu/odata/sap/Z_TEST_V2_SRV/Entity_Set_Name/?$filter=Filter1 eq 'value1'and Filter2 eq 'value2'
    So, while creating XSD from XML should we need to use the above URL or http://xxx:8000/sap/opu/odata/sap/Z_TEST_V2_SRV/?$format=xml
    If we are using http://xxx:8000/sap/opu/odata/sap/Z_TEST_V2_SRV/?$format=xml and convert it in XSD then we are not able to see FEED in the MBO creation.
    Also, if we are using http://xxx:8000/sap/opu/odata/sap/Z_TEST_V2_SRV/Entity_Set_Name/?$filter=Filter1 eq 'value1'and Filter2 eq 'value2' and convert it into XSD then we are able to see the FEED in MBO creation but while choosing the fields it is throwing us java.lang.nullpointer exception.
    Can anyone explain us the solution for the problem?

    Is there a particular reason why SUP 2.1.3 is used and not the latest 2.3.4?  It is recommended to move to the most recent version if possible/new project.
    For HWC consuming OData service, you can connect directly from your JavaScript without using MBOs.  Please take a look at this link:

  • Consuming oData service from SSIS 2008 R2

    Is there possibilities to consume oData service feed from SSIS 2008-R2, any component that can be used ?

    There is no such built in specific functionality, but an OData feed is typically merely a WebService which an HTTP call away that you can do using the WebServies task, download as XML and process.

  • Consume oData service in WebDynpro ABAP

    Hi All,
    Is it possible to consume a oData service from one SAP system in to another system (assume in a report program or WebDynpro application)?
    If yes, can you please guide me?
    Thanks in advance....

    Hello Chandra,
    Do u have a scenario/requirement where u want to consume a GW Service from WebDynpro screens ?
    Is it really required ? if at all you want to consume GW service from WebDynpro screens, i think using GW is not a correct solution.
    There would be some other ways to consume your Back-end business logic from WebDynpro screens.
    I don not know if we can call GW Service in a WebDynpro screens. Technically if its possible also then i think its not correct to do that.
    In my opinion GW has to be used in combination with UI5 for light weight applications.

  • SUP 2.1.3 MBO creation using ODATA service

    Hi All,
    I am using SUP 2.1.3 and trying to consume OData service created using SEGW transaction on gateway. following an older document i moved ahead by creating XSD files from the XML file.
    But,after uploading the XSD file , i chose the root element as 'feed' .
    After this , one XSLT file is generated automatically.
    But , when I click the XSLT file to edit , it shows error saying  'java.lang.NullPointerException' .
    I have to follow the methodology of creating MBO's using OData service and then deploying it on server.
    Please help me to move ahead with ODATA service in SUP 2.1.3 version. 
    Appreciate your quick help and assistance on this.

    If i ignore the Null exception error and move ahead with the XSLT format and preview the data source i receive the below error:

    These are REST services
    If you google "windows forms consuming rest services" there are a stack more hits.

  • Odata services in Design studio 1.2 ?

    Hello All,
    I am exploring Design studio at the moment and I know that we can do scripting along with drag and drop functionalities.
    But I would like to know if it also possible to consume Odata services or send Odata requests to HANA database to get data back and display on charts or tables and so on.
    Any help would be appreciated.

    Hi Sangamesh,
    Based on what you've described, I'd say it's most likely you will need to create a Calculation View.  For more general information about using HANA with Design Studio you may find the following posts useful:

  • Access cloud for customer Odata Service from HCP

    I have a UI(sapui5) which consumes ODATA Service from "cloud for customer" system.
    I am using connectivity proxy servlet(using destinations) to avoid cross origin issue.  when i deploy and access this UI from cloud, the response of the odata service is " HTTP status 500 peer not authenticated".
    I tried giving the http url and that says "502 bad gateway".
    How to resolve SSL issue for cloud.?
    Is there any other configuration that needs to be done to consume ODATA from "Cloud for customer" system

    Hi Priyal:
    For the SSL handshake at the destination level either you would have to set the property "TrustAll=TRUE" or you have to create a JKS keystore which contains the Server Certificate for the Cloud for customer system and then upload this either via the Admin cockpit (at destination level) or deploy the same via the NEO console tool.
