Re: Echoing

["Phil Wang" <pywang@nortelnetworks.com>]

Did you get my last email regarding the ANTS?

Your this problem is caused by the same reason that the JDK versions are
different for ORE and your modified example. There is actually some
incompatibility beteen JDK 1.1.7 and 1.2.2. To solve it, try to
recompile your example using JDK 1.1.7.
