I started web service hello example in J2EE tutorial. I had a very similar problem. As I read this posting, I found a problem where sun-acc.xml in the domian1 directory did not have a correct URL to my laptop. After I corrected this wrong URL and restarted the glassfish server, the probelm was gone.
