About openstreetMap API used in GWT Application

HI,

As I am using gwt-openlayers-client-1.0-SNAPSHOT.jar into GWT application. And is able to show the openstreetmap on the application but the problem i am facing is how to get the way id by selecting a building. i.e i want to make my map editable so that user can select any building and get its way id. like the same you have on your website when we select the checkbox of "Map Data" then the way become hyperlinked and we can select any building and get its wayid.

Please help me out to do this through API.

Also i have tried to embed your website(www.openstreetmap.org) into my application but it is giving me error of X-Frame="SAME ORIGIN" and it is not showing up on my application.
