Thanks Willem, thanks Henryk for your suggestions.
Will try that to find out what makes most sense.
In fact, I tried the following which seemed to work
from("timer:httpRequestTrigger?repeatCount=1").to("http..
Isthere actually a real use case where from(http://...) makes sense?
Whats are the reasons to prefer
from(...).enrich("http://...";).to("file://...")
to
from(...).to("http://...";).to("file://...")
For this question, RTFM would be a valid answeri guess...but maybe someone
could give a brief answer, please?
(as I didn't find an obvious reason on http://camel.apache.org/http.html)
Thank your for your comments
kind regards,
Christian

Just a little addition to Willem's answer.
If you need to issue HTTP request on demand (for example once) do not
use HTTP pull consumer, as you don't want to scan the endpoint
continuously. Instead trigger the HTTP enricher [1] on some event.
from(...).enrich("http://...";).to("file://...")
or
from(...).to("http://...";).to("file://...")
Some event sources you might be interested in:
___DIRECT___ [2]
Route:
from("direct:httpRequest").enrich("http://...";)...
Client:
producerTemplate.sendBody("direct:httpRequest", new MyHttpRequest())
___TIMER (ONCE)___ [3]
Route:
from("timer:httpRequestTrigger?repeatCount=1").enrich("http://...";)...
No client code is needed in this case.
___GUAVA EVENT BUS___ [4]
Route:
from("guava-eventbus:httpRequestBus?eventClass=MyHttpRequest").enrich("http://...";)...
Client:
@Inject EventBus httpRequestBus;
...
httpRequestBus.post(new MyHttpRequest())
