Hi Sunny, I can't say for sure what's going wrong in step 3), but to help figure it out I wanted to suggest a couple of things to narrow it down.
Before that, a quick note about the size of the data you're sending over - it doesn't seem like the size of the objects you're sending back would be sufficient to stall the response, but could you try with a smaller data set just to see how the RPC call responds? That would clue us in as to whether the data you're sending is causing the problem. If you could also track the size of the payload being sent over the wire, that would also be helpful. Now more troubleshooting suggestions: 1) Could you try debugging through your server-side code, up until the point it returns the response back up to the hosted mode browser? As you mentioned the method itself runs and returns fast enough, but I would to make sure there isn't some RemoteServiceServlet boiler-plate code where the response is getting trapped and taking longer. Since your application seems to work fine in web mode, this is probably unlikely but worth checking out. 2) Could you try running hosted mode with the -noserver option, using your production server instead of the embedded Tomcat instance? This would help isolate the problem to either the embedded Tomcat instance or the hosted mode code dispatching and running the asynchronous callback. Hope that helps, -Sumit Chandel On Tue, Sep 23, 2008 at 7:07 AM, sunny_zhou <[EMAIL PROTECTED]> wrote: > > Hi Sumit, > > Thanks for your reply! > > I'm a beginner at GWT, so try to be patient with me, i will try my > best. > >> Could you be a bit more specific about how much stuff is crammed into >> the POJO that is being sent through RPC?
