Access Ivy project classloader on jar

Hi all

I'm using a htmlUserDialog wich JSF and i have a jsf custom tag, i build and put it on webapp folder of server. this is a custom tag that i will use on my xhtml. this tag somehow is a jsf event listener, it listen system event of jsf (ex: PostAddToView, PreRenderView,...)

Sometime when i start ivy engine (via Windows services), i got exception:

ch.ivyteam.ivy.environment.EnvironmentNotAvailableException: Access to ivy environment outside a process request thread is not possible.

In my jar file, i need to access to ivy project class loader, so i have this line:

 ClassLoader cl = Ivy.request().getProject().getProjectClassLoader();

I have a interface in this jar so i need to get class loader to find which class (from ivy project) is implementing my interface (vis ServiceLoader)

I guess my jar is started before ivy initialize its environment. So how can i solve it ?

P/S: when i try to start some more times, my engine can start but this exception is quite annoying imo

Thanks
