Hi, > Some said GAE did not support DWR while I had read about >> "Will it play in App Engine".It showed that " >> Direct Web Remoting (DWR) >> Version(s): 2.0.5, 3.0 RC1 >> Status: COMPATIBLE"
DWR uses threads for some things like reverse ajax. For sure, that will not work in appengine at least the way 3.0RC1 is written. It also writes files that don't work on appengine. Long polling isn't supported either. I've seen people on the DWR list try to work around that, but I've never seen a clean solution. Maybe there is one though. Here are relevant posts from the DWR list http://old.nabble.com/forum/Search.jtp?forum=13934&local=y&query=dwr+appengine Anyway, your "undifined" error is most likely: 1) the path to the DWR script is wrong 2) the path is correct but when your javascript on the client loads, it send a call to the server to configure DWR. But by the time the call returns, your javascript on the client has already moved on and thrown the undefined error because DWR hadn't returned in time. I saw this with reverse ajax.
