Hi,
I started tutorial about using appengine sdk in gwt project
(stockwatcher example).i followed the instruction and changed
build.xml file to make them working together,but i'm getting an error
in taskdef 'path to gwt not found'.when i hover mouse over yellow
triangle it points at the right path,but it seems not see gwt.sdk
there.i don't know anything about ant and configuration in build.xml.i
read that project hierarchy might cause such problem,so i tried
changing the order in every possible way.can someone help me out with
this problem?i found older thread about the same issue but the
solution points at the tutorial i was using.
Thanks,
Ania
