[Jihnd]

hello all,

i'm folllowing the samples in bill burke's ejb3 book, i''ve successfully deployed my ejb bean, and i've got an simple database i've made in oracle xe as my datasource

i'm now at the stage where i'm tryng to access i through a client application - but whenever i run the client app, it hangs about 4/5 hours - after which i get these error messages:

(reconfigured port to 1201 for my install)

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:
