[orion-dev] How to properly set {OrionHome} (WAR file issue)

[Javier H Pedemonte <pedemont@xxxxxxxxxx>]

I've been trying to get Maqetta/Orion working
when running from a WAR file [1].  We've fixed most of the Maqetta
issues and identified some Orion ones.

Now, I'm running into an issue where
the Orion client doesn't work, due to the "OrionHome" variable.
 As part of https://bugs.eclipse.org/bugs/show_bug.cgi?id=373450,
it was set to the hostname of the loaded URL.  The problem is that
when running from a WAR file, all URLs contain a base "context",
corresponding to the name of the WAR file.  In our case, with a release
named "maqetta.war", all URLs look like http(s)://[hostname]/maqetta/...
-- but Orion fails because "OrionHome" is missing the "/maqetta"
bit.

I think I should be good to go if I
can just properly set OrionHome in the 3 or 4 places it is set; most of
Orion client seems to make direct use of this variable.  The question
is how to set OrionHome correctly?  Does Orion already have some core
code that could be useful in this case?  Is there an easy way to determine
from which base URL Orion is running?

I already have some code (a bit of a
hack, really) on the server that can tell if Maqetta/Orion is running from
a WAR.  But what's the best way to get that information from the server
to the client code?  If someone could point me to the correct Orion
classes, I could get this working...
