Using javascript variable from GWT Java

Question

I have defined a javascript variable in head section of html file. E.g var yourName = "Nadeem"; Now I want to utilize this variable in my gwt java file/class/method. But it shows an error: Undefined. Please suggest some hints. Best Wishes.

The trick is to use the right "context" where the variable is defined, i.e. $wnd:

static native String getYourName() /*-{
   return $wnd.yourName;
}-*/;

It was so hard to find this solution. I'm glad it was easier than I was imagining in my head. Thanks!
