OK that hellped. What I ended up doing was:
* Component extends UriEndpointComponent
* Endpoint extends DefaultEndpoint and is marked @ManagedResource and
@UriEndpoint. It also has a @UriParam for 'baud' and another one for
'path' -- that last one is a problem (will explain in a second)
* Consumer extends DefaultConsumer and uses a processor to launch events
The endpoint is marked like this:
@UriEndpoint(scheme = "jssc",
syntax = "jssc:path",
consumerClass = JsscConsumer.class,
title = "JSSC Component")
I would like to be able to do this:
from("jssc:com10?baud=19200")
but THIS still does not work:
@UriPath
@Metadata(required="true")
private String path
so I end up having to do this:
from("jssc:com10?path=com10&baud=19200")
What is wrong with specifying it as a path parameter whose name
matches the 'syntax' in the @UriEndpoint annotation - shouldn't that
work?
