Not to use end() at all.
They should only be used for some special EIP that kinda have sub
routes, such as
- aggregator
- splitter
and a few others
So your route should just be:
from("direct:start")
.process(new Processor(){
public void process(Exchange arg0) throws Exception {
System.out.println("hello!");
}
});
