GWT library for indexedDB

Is there a GWT library for HTML5 indexedDB functionality?

Or, alternat开发者_JS百科ively, is there a Javascript one I could wrap for GWT?

I tried to write it with JSNI but it was useless because of the lack of support by browsers and different "strange" behaviors. Then I emulate is by using java Maps it has some essence of the indexedDB but not perfect solution

also now there is http://code.google.com/p/indexeddb-gwt which seems to be promising

There is a project on Google Code, but it looks like there is nothing there. You might want to contact its owner and ask what the state of the project is:

http://code.google.com/p/gwt-indexeddb/

Or just role on your own using JSNI...
