xpages extension library deployment in domino server

I deployed the XPages Extension library on my domino server 8.5.3 by following these steps :

1 / Download and unzip the openntf library on the server.

2 / Create an update site and import the site.xml on the server.Everything is imported, enabled and signed with the server id.

3 / In notes.ini , add the following line: = OSGI_HTTP_DYNAMIC_BUNDLES UPDATESITE.NSF (my update site)

4 / I restarted the server and got this message :nsf based plugins are being installed in the osgi runtime

5 / Check the two libraries to use in XPages application in the application properties in the library extension XPages app demo .

I still have a display like this the extension library is not recognized although it works well when the application is on my local machine (I installed the extension library also in my local machine). Is what I missed a step in my deployment ?
