ant: External entity not found

[ittay.dror@gmail.com]

Hi,

I have a build.xml with the following header:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE project [
<!ENTITY configure SYSTEM "file:../../build/etc/configure.xml">
<!ENTITY % openbuild SYSTEM
"resource://com/tikalknowledge/openj2ee/openbuild/common.ent">
%openbuild;
]>

When I launch ant, the jar that holds common.ent is in the classpath
(by setting it in LOCALCLASSPATH variable).

I get:
/build.xml:4: External entity not found:
"resource://com/tikalknowledge/openj2ee/openbuild/common.ent"

Please help,
Thanx,
Ittay
