The trouble is that resource interfaces aren't general Java interfaces;
they must be compatible with HTTP methods.
You have two methods annotated with @Get("json"), neither of which is a
valid target for @Get. @Get should only annotate no-arg methods that return
an object reference, @Post should only annotate one-arg methods, and so on.
In addition, there should be at most one @Get operation per metadata
argument (and at most one with no argument) on a resource interface.
You can achieve something of the effect that you're looking for by
designing your resources' URIs so that what you model as arguments to your
get method are actually encoded as part of the URI, either as query
parameters or as components of the path.
And while I understand that you are just experimenting in your example, I
do recommend reading (if you haven't already) books on RESTful or
resource-oriented design.
