Can anybody help me with the following problem:
I am trying to use Intake and I have made sure that all the necessary
steps have been taken. When I compile the project, start tomcat and get
to the
TestIntake.vm file in the browser, I get $intake.declareGroups() as
text, it is not resolved. However, when I copy the same project on some
other machine running the same version of TDK-2.2,
$intake.declareGroups() is resolved (project is NOT recompiled on that
machine.just copied).
What is missing?
Here are the necessary files:
