Google Web toolkit and AppEngine are working together very well. But I found a lot of tutorials showing GWT script and AppEngine are sitting in a single box. But I believe that should be able to send RPC calls to a separated servers. Google Map GWT library is to send RPC calls to Google Map Server. So, there should be a way to write an application with a separated GWT client script and AppEngine.

(Note: I found after the service class casted to ServiceDefTarget, I can use setServiceEntryPoint to a remote server. But our web browsers has Single Origin Policy, which blocked the request to remoted servers. I am checking whether any work around.)

I read a blog post from Android Developers Blog. There are a step-by-step tutorial for Gestures API. Finally, I got a more clear picture. Those gestures are to control the action of applications, like a shortcut. For example, you can write a circle on a screen, that means "Open a new file".

I found Dell 11 Z series is available in Australia. That looks a CULV laptop, but it got an Intel Pentium Dual Core SU 4100 CPU, rather than a Duo Solo. That sounds more powerful than there. Moreover, the sepcifications are included 2GB and 250GB Hard disk, that sounds a full-scale notebook. I can say that is a thin laptop without DVD-Rom.

In the most of case, Google Web Toolkit is using with AppEngine. But it can convert Java code to Javascript. It can used in s client-side only scripting environment. Yesterday, I wrote an example page with some Ajax requests to an external web services. That is very easy. I used Google Plugin for Eclipse.So that, after I finished coding, all I need to do is compiling the project. Then it will generate the html files and javascript under /war. Finally, I copy all files to my web root under Apache. Then done. I can view the webpage in a normal web browser.
