HeadlessException - X11 OK

[iksrazal]

Hi all,

I'm trying to run tcpmon remotely. I'm using X11 forwarding over ssh.
X11 is
working fine - I can type 'xclock' via ssh on the remote machine and it
works.

However, I get this error:

/home/iksrazal/axis-1_3/lib> java -cp axis.jar -Djava.awt.headless=true

org.apache.axis.utils.tcpmon 8090 localhost 9081
java.awt.HeadlessException

As you can see I've tried java.awt.headless=true . Any ideas?

What happens if you do not specify headless? After all, if X forwarding
works, why castrate your application in this way?

Yeah that was it. Moral of the story - X11 forwarding needs to be
turned on server-side - don't use java.awt.headless=true .
