Actually, yes you can.=A0 That's the whole point of the new resource load=
er=20
concept in XMLC 2.3.2.=A0 It's THE central location for ALL resource look=

XMLC.=A0 You can verify this yourself by using the custom document/resour=
ce=20
loader I sent you earlier and logging the paths that are requested just b=
efore=20
the URL is looked up and returned.=A0 You will find that the path for the=
 SSI=20
include is looked up.=A0 After all, there's no parsing a URL before the U=
RL is=20
obtained.=A0 And the resource loader is what obtains the URL.

So, all you need to do is let the classloader return the URL.=A0 Then che=
ck=20
URL.toExternalForm() (or URL.toString) for the path being both a "jar:" U=
RL=20
and having ".." in the path.=A0 If so, then manipulate the path resolving=
 the=20
".." bits to the canonical path without "..".

I wonder if Java 1.4+ URI class might do this for you without extra manua=
l=20
manipulation?=A0 You might want to look into that.=A0 You also might want=
 to=20
report this as a bug or feature request against JarURLConnection to Oracl=
e (I=20
wanted to say Sun).
