Re: [jBoss-User] Naming exception in standalone Tomcat

[Aaron Mulder <am...@alumni.princeton.edu>]

	This is something that used to work and seems to have stopped
working.  It's not clear whether it was a Tomcat change or a jBoss change
that caused the problem, but we are aware of it.  As a workaround, you can
manually load the jndi.properties file into a properties object or the
system properties.  Also, the new embedded tomcat service should solve
that problem if you're running the two products in the same VM, but the
directions for that are not yet in the manual.
	For the benefit of the Tomcat folks, I think the JNDI code uses
getResources to look for jndi.properties, which is not implemented in
AdaptiveClassLoader, but I'm pretty sketchy on that, and I don't know why
it would have worked before (unless this was caused by one of the Linux
JDK 1.3 updates?).  Unfortunately the JNDI code is pretty grim.
