Call jspdynpage or Abstract Portal Component from SAPUI5

Question

Hi,
I am new to SAPUI5, so might ask basic and dumb questions.
I am trying to develop an application in sapui5 which should have the functionality to read and write a file to the server. It is different from file upload as the user wont be selecting any file, rather the data in the form should be written to a file in the server on a click of a button. After doing some research I figured out that sapui5 doesn't give an option to read/write a file to the server.
So, as an alternative I thought of developing a service, an SAP portal application (jspdynpage, WDJ, abstract portal component - or if you can suggest any other app) that can be called from the sapui5 for reading/writing purpose. The data can be received/sent as an xml, and in the sapui5 application I can parse the data and do the needful.
Now my question is how to call the portal application (that would be a url) without redirecting, and pass the necessary parameter? Sapui5 should just call that url and data should be passed or received as a parameter. I am not sure if OData model call will work, as I am getting an exception. Can you please provide a solution to this?
Ps: We are on SAP EP 7.3 and would like to stick to SAP apps, and no additional database etc.

Hi All,
I found a way to do that. I created an Abstract Portal Component application that accepts data through url parameters. Used the regular java APIs to read/write files to the server.
Now the challenge, at least to me, was to call this application from SAPUI5 application. I used ajax call.
var response = $.ajax ({
     url: "<url>",
     type: "POST"
Next, will also try to find if I could use any of the models provided by SAPUI5 to call the portal application.
Note: Make sure both your sapui5 app and the portal application is deployed on the same server, else it wont be able to authenticate (SSO wont work) and you may receive exceptions.
