Uploading a extended Fiori project

Hello,

I am following this document

https://websmp210.sap-ag.de/~sapidb/011000358700000072302014E.pdf

to extend a Fiori app.

What I did was:

1: Download the standard app from /nSE38

2: Import the downloaded code to WebContent folder

3: Create an extension project and a Launchpad sandbox

4: Extend the app in extension project and test in sandbox.

Now I want to upload the extended app to NW Gateway server. I went to /nSE38 -> /ui5/ui5_repository_load

But I do not know which folder to upload.

I tried to upload the WebContent folder of extension project, but what I saw from /nSICF service was a blank page. The 'Test Service' in browser redirected me to index.html page, which contains only a blue crystal background image.

Looking forward to your help.

Thanks in advance.

Kenny
