Connection to ODATA service not possible from UI5

Hi Gurus,

I am new to UI5. The issue that I am facing now is I am not able to connect to ODATA service.

Previously it was working fine and all of a sudden, it stops working. One thing I noticed is that the

windows security warning that used to pop up while connecting to the web service has now vanished.

It is not showing up now.

The code I used is :

var oModel = new sap.ui.model.odata.ODataModel("http://seasrv05.applexus.com:8000/sap/opu/odata/sap/ZAPLX_TS_USER_VALIDATE",true,user,pass);

Pls help me.

Regards,

Ashish Kumar
