in my searches it seems to be the jndicontext.lookup variable that could an issue, so
i've been trying a variety of names including (AVman is the nname of my jar & the
jndi name) "java:AVman/com/AVman/Audiorec/AVmanRemote",
"java:com/AVman/Audiorec/AVmanRemote",
"java:AVman/com/AVman/Audiorec/AVman/remote"
but no joy
my log gives me a series of these errors:
