GateIn 3.2 packaged with JBoss AS 6 has a known issue due to fetching some .xsd files from slow to respond servers on the web when it should be finding those locally.
Try to use JBoss AS 5 packaging instead - it does not have that problem.
Or, if you don't need WSRP you can disable it, and circumvent the issue that way.
You can also download GateIn 3.3.0.Final which has just been released. If you need WSRP, use JBoss AS5 packaging, otherwise give JBoss AS7 packaging a try - that one starts up pretty quickly.
