How to show a User view in GWT app by typing in browser address bar

I have this gwt app which say, runs on http://mygwtapp.com/ (which is actually: http://mygwtapp.com/index.html)

The app host a database of users, queried by searching usernames using the search view and results are shown in the user results view. Pretty useful enough. However I need to bb add a way that user view can be viewed by just typing http://myapp.com/user123

I am thinking that the question I have here, the answer is a server side solution. However if there's a client side solution, please let me know.

One fellow here in StackOVerflow suggested tha开发者_如何学Ct the format would be like this: mygwtapp.com/index.html#user123

However the format is important to be like: http://myapp.com/user123

The 'something' in 'http://host/path#something' is a Fragment identifier. FIs have a specific feature: the page isn't reloaded if only FI part in URL changes, but they still take part in browser history.

FI's are a browser mechanism that GWT uses to create "pages", i.e. parts of GWT application that are bookmarkable and have history support.

You can try to use an URL without # (the FI separator), but then you will have a normal URL, that reloads the page with every change and it could not be (easily) a part of a normal GWT app.

mygwtapp.com/index.html#user123 That would be using the History mechanism (http://code.google.com/webtoolkit/doc/latest/DevGuideCodingBasicsHistory.html) which I would add is the recommended way of doing it.

However, if you insist on using something like http://myapp.com/user123, one of the possible ways is to have a servlet which accepts this request (you might have to switch to something like http://myapp.com/details?id=user123). The servlet will look up the DB and return your host html back. Before returning it will inject the required details as a Dictionary entry in the page (http://google-web-toolkit.googlecode.com/svn/javadoc/1.5/com/google/gwt/i18n/client/Dictionary.html) On the client you can read this data and display on the UI
