This is how you collect strings from JSNI fn
public static native String stringExample() /*-{
return "String1";
}-*/;
This is how you pass a string to JSNI fn
public static native void alert(String msg) /*-{
$wnd.alert(msg);
}-*/;
Hope this is what you were looking for.

I need to know when I call a javascript function, how to pass it to the java code in gwt.Like if I had a function that returned a string in javascript when i called that function it would send it to the java code to say update a textBox. Hope that makes sense.

@james You just use the functions as Java functions now. The js code has been wrapped in a java function. so in gwt use String gwtString=Class.stringExample(); Class.alert(gwtString);
