here's one approach to running GWT apps from within Web2py (approach
adapted from basic pyjs' approach).
in your controller e.g., user.py
def gwtapp():
return dict()
in applications/app/static directory place war directory (rename war to
enable use of multiple GWT apps) e.g., app1
in applications/app/views directory create user/gwtapp.html
in this file place the main HTML file from your GWT app.
You can edit this file to your hearts contents but the essential change is:
<script type="text/javascript" language="javascript" src="{{=URL(r=request,
c='static',f='app1/gwtapp_name/gwtapp_name.nocache.js')}}"></script>
Place any functions you want your GWT client app to call in the controller
user.py.
That's all the web2py requirements.
In your GWT Java file, to perform JSON calls you'll need to call a function
in a Web2py controller function...
A hack is required to construct such URLs.
To create an URL for the function get_user_profile() call the following
function and append "get_user_profile"
private static String GET_SERVER_URL() {
String url = GWT.getHostPageBaseURL();
if (!GWT.isScript()) {
url = url.replace(":8888", ":8000");
url += "init/user/";
}
return url;
}
private static final String JSON_URL = GET_SERVER_URL();
This will return the correct content whether you run Web2py or dev_appserver
.py (both of which run GWT JavaScript) or run the Development Mode of GWT
which runs Java byte code (ie !isScript()). For the latter, you'll need to
launch your Web2py server app on default 127.0.0.1:8000 and the GWT
Development Mode app on default 127.0.0.1:8888.
Setting up a call to the server might look like this:
RequestBuilder builder = new RequestBuilder(RequestBuilder.GET,
URL.encode(JSON_URL
+ "get_user_profile"));
I've left out Java import statement but IDEs will typically shout and
insert them for you.
