Is there an IDE for editing Camel routes?
Apache Camel offers no IDE out of the box.
You could use your Java IDE for smart completion when creating Java routing rules via the DSL which will give you smart completion in Java code.
Or you can use your XML IDE (with XSD smart completion) to edit the routing rules in XML using the Xml Configuration
Some of the Commercial Companies offers IDE's and other tooling for Camel.
