How to get the URL of a process start within a JAX-RS class

Hello IvyTeam,

My Ivy Version : 7.0.3 I would like to get the url from a process in a JAX-RS Rest Resource but I get an Exception with this code:

Ivy.html().startref("Functional Processes/dis/videoIdentification/start.ivp")

The JAX-RS Resource is located in the same project as the process. It works without problem in a Process (IvyScript Step).

I can imagine that the fact the code is in a JAX-RS Resource does not allow accessing some Ivy resources like the ProjectModelVersion Provider. Is there a workaround for that? Or do I have to compute the url more manually with the InetAddress and so on ? By the way this code works in this resource: Ivy.html().applicationHomeRef()

Thanks in advance

Here the StackTrace I get:
