May be ANT is dropping the jar you have arranged in classpath because it
points to non-existent file location. Run ant in verbose mode (ant
-verbose) and check if the required jars are infact set in classpath.

Looks like org.jnp.interfaces.NamingContextFactory is not in the classpath. Is the jar that
has this class in the classpath ?
