Sacha;
I am not that familiar with the client side, but in
the JBoss server code, the jndi.properties file is
loaded as a class resource, implying that it must
simply exist somewhere in the classpath. If this is
the case in the client, surely the file could simply
reside in a downloaded jar file, no ?
