As you can see from the above Camel uses URIs to wire endpoints together.

URI String formatting

Available as of Camel 2.0

If you have endpoint URIs that accept options and you want to be able to substitute the value, e.g. build the URI by concat the strings together, then you can use the java.lang.String.format method.
