interpreting netstat output

Yes, the port is up and waiting for connections, ie. the app/demon behind it. Connections usually are seen with client IP addresses where the *.* is and also with something like "ESTABLISHED" as status.
If you see a name at the positon where the 8090 is, this is translated from the /etc/services, where port numbers can be mapped to a service name.
Next time please checkout a more appropriate subforum since this is "Shell Programming and Scripting"

Hi there again,
Running Solaris 10 with built-in Java. Seems to compile and run fine.
Problem is: Say I want to see contents of current directory. In a shell, I'd just write "ls" and it outputs the content.
When I write a Java file, I have the following line:
System.out.println("ls");

Roland Dreier <rolandd@cisco.com> BUGS
The network synchronization between client and server instances is weak, and does not prevent incompatible options from being used on the two instances. The method used for retrieving work completions is not strictly correct, and race conditions may cause failures on some systems. libibverbs August 30, 2005 IBV_UC_PINGPONG(1)
