Hi Claus again,
I addition to what i asked in my previouse response here is a question
regarding the producer snippet which you gave in your last answer:
I indeed wrote the following in my process() method:
ProducerTemplate producer =
exchange.getCamelContext().createProducerTemplate();
Object response =
producer.sendBody("http://myserver.com/myapp?foo=bar";, "Liav Camel
POC");
but i don't have the camel context at hand (saying "The method
getCamelContext() is undefined for the type Exchange").
& also do i need to deploy a camel http producer su instead of an http
service mix provider?
