I've been trying to implement a dispatch interceptor for commands in my
java component without success. I've been checking different examples on
the list and the developers guide but couldn't get any of those to work
properly. I don't really know how to connect the interceptor to the
actual writer component. As I understand it the Frame has to be
connected with the XDispatchProviderInterceptor, which is implemented in
my Interceptor class. But how am I connecting this class with the frame?
This is my Interceptor class, which I'd like to start up from another
class where I do create a new writer document.
