I do not suggest to use Kawa as a servlet, rather to make a servlet which parses the http parameters, and which keeps an instance of a Kawa iterpreter as a state variable (not instantiated for every http connection, but in the Init() method of the Servlet). It could then evaluate a command, builded from the Http parameters. 

you could bind a variable in your Kawa interpreter (using "define") with one of your application objects, or have a static method giving access to your application objects, that can be accessed from kawa...

what do you think?

seems clear?

How could I access my apps objects if I have
