Plugin doesn't deploy on Glassfish 2.1.1

Using Helios SR2 + Glassfish 2.1 J2EE 5 runtime and Glassfish 2.1.1 I'm trying to deploy 'hello world' dynamic web project. Server has status [Started, Republish], application [Synchronized] but nothing happens, application is not reachable and visiting url gives 404. No trace of deployment in log. I tried to put my hello world thingie into Enterprise Application Project but it doesn't fix (read somewhere here that it solved other problem with the plugin). I see no error messages in the log, nothing about deployment can be found in server log. Logging in into console shows no web applications deployed. When I export war and manually deploy it using GF admin console it's deployed properly.
I also checked Glassfish 3.1 (same project) and it's deployed properly from Eclipse. I suppose there's problem with plugin or some of my setup. What's more confusing is that I've checked that on 3 different PCs (1xCentos x86_64, 2xWXP), with newest JDK and everywhere I have the same problem.
Any suggestions? Are there any logs that plugin could produce? How to enable 'em? Where to fine 'em?
Thanks in advance
