Hi Williams,

The error 500 indicates the internal server error.

I think you need to perform a read service like:

oModel.read('/Path', null, null, true,

function(oData, oResponse)

{

  alert("Read successful");

  },

function(error){

alert("Read failed");

}

);

Thanks,

Deepak.

Hi Deepak ,

                        i followed you my oModel giving response Failed......plz can you tell me my model is right or wrong?

Hi ,

Below code is the example for a read service by using Northwind services:

var model = new sap.ui.model.odata.ODataModel("proxy/http/services.odata.org/Northwind/Northwind.svc",false);

  model.read("/Categories",null,null,

  false,

  function(data,response)

  {

alert("success")

  },

  function(error)

  {

  alert("error");

  }

  );

Please try this code in your oninit()

and debug it weather you are getting success alert or not.

Thanks,

Deepak.

Hi Deepak,

                    i try this its working fine success message is populating but it is in the case of Northwich service only not in my service

Now you try your service URL in the place of Northwind Service URL and check it by placing a break-points.

Thanks,

Deepak.

Hi Deepak,

                  still not working....

is this the right way to access a serivce with username and passoword.

var oModel = new

sap.ui.model.odata.ODataModel("proxy/http://ugcdcc.cdccc.com:8250/sap/opu/odata/SAP/ZDEMO_PR_SRV",false,"mark","mk@1234");     

oModel.read('/PRHeaderCollection', null, null,false,

  function(oData, oResponse)

  {

   alert("Read successful");

   },

  function(error){

  alert("Read failed");

  }

  );

just a small mistake in the url

replace your URL

"proxy/http://ugcdcc.cdccc.com:8250/sap/opu/odata/SAP/ZDEMO_PR_SRV"

with:

proxy/http/ugcdcc.cdccc.com:8250/sap/opu/odata/SAP/ZDEMO_PR_SRV

OR

http://ugcdcc.cdccc.com:8250/sap/opu/odata/SAP/ZDEMO_PR_SRV

Please observe the difference

hope you will get this time.

Thanks,

Deepak.

now its giving this error.....

[former_member203031 · Accepted solution]

please check in the screen shot at the line problem access

the url is still proxy/http://somehting

Hope this is the reason for the error.

As it is saying that the connection is refused by SAP with this URL.

Once you please clear the cache and check it.

Thanks,

Deepak.

i clear the cache but still getting error.

[former_member203031 · Accepted solution]

instead of using proxy/http

Try with http://your URL

Thanks,

Deepak.

Try by making the URL dynamic:

to get the dynamic URL please follow:

var origin  = window.location.origin

var my_url = origin+"/sap/opu/odata/sap/Zdemo_pr+srv"

Thanks,

Deepak.
