a server..So i am writing a j2me code to create java app. So its
basically j2se(Netbeans) - j2me socket communication.A simple hello
world communication btw them works perfectly in a simulator!!..but
when i try to deploy it in mob...its not working...i tried creating
adhoc network /9win 7)btw mob and lap..but its not communicating..then i tried
with a s/w Virtual Router..When i used it..it communicated ..but the
s/w crashed after its first use..so i m not able to proceed..my whole
project relies on this communication..if it works i have to proceed to
file and image transferring using sockets..So pl let me know where i m
going wrong..or i need to change anything..PL HELP ..
