Hello,
It's my first time to use ApachCXF-2.7.0.
I got some strange exception "HTTP response '400: Multi-Hop Cycle
Detected'" but I don't know why I got this?

The following is my code.

MyServiceService port = new MyServiceService(new URL(SERVICE_URL),
SERVICE_NAME);
MyService service = port.getMyServicePort();
service.echo("Hello World");
service.echo("Hello World again");

I found that if I use the service to call more than one time, it will raise
that exception. I mean if I only call the "service.echo(....)" once. No
exception at all.
What's wrong with it? I tried Metro and Axis2 before, it allows call multi
times with one port.
Any idea on it? Or I need to add some special configurations for that?
Please help!!!
Best regards,
Eric
