How do call tcp java.Can u give the example?

I think the Port numbers used in your Java programs are not correct. Maybe you use the Port numbers < 1024.

这和操作系统没关系，你的程序写的有问题

oh , i forgot the port < 1024 , it's ok now .

[gzwrj]

this may be help u:
In UNIX environments port numbers below 1024 are reserved and can be bound or used only by root (superuser). So if the non-root users try to run the application they will receive an error message saying that

"java.net.BindException: Permission Denied"

There are two ways to avoid this exception. One way is to login as root and run the program. The other way is to specify a port greater than 1023
