Here's the output: (this is what I'd expect, given that I have
D:/ejbpeople/projects/build-app/conf on the classpath.
Trying to read jndi.properties
from:file:/D:/ejbpeople/projects/build-app/conf/jndi.properties
My settings for D:/ejbpeople/projects/build-app/conf/jndi.properties are:
java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
java.naming.provider.url=localhost:1099
java.naming.factory.url.pkgs=org.jnp.interfaces
I'm still getting the same exception:
Cannot instantiate class: org.jnp.interfaces.NamingContextFactory
javax.naming.NoInitialContextException: Cannot instantiate class:
org.jnp.interfaces.NamingContextFactory. Root exception is
java.lang.ClassNotFoundException: org.jnp.interfaces.NamingContextFactory
Thanks for your help,
Rick
