Andrea Cosentino commented on CAMEL-16243:
------------------------------------------

3.0 Rc2 components can only be used with 3.0 Rc2 core. So it's normal it doesn't work with 3.2. restlest has been removed and you should use camel rest

> Recently we upgraded our Application's overall camel version from 2.16.0 to 3.4.4
> One of the component we used in our Application was camel-restlet component (version 2.16.0). 
> Issue #1 : It seems camel removed the restlet component after 3.x. Could not find much documentation which would let us know how to migrate the existing camel-restlet component
> Issue #2 : We gave a try to upgrade the camel-restlet component to 3.0.0-RC2. But during start-up of our service, we faced an error as mentioned in the below stack trace.

> Found in the code that RestletComponent java class in camel-restlet-3.0.0-RC2 version has an API doStart() in which at line 215, there is a call to CamelContext class's method getRestConfiguration("restlet", true) (class in camel-api jar).

> The API called at like 215 above (i.e. getRestConfiguration) seems to be removed by Camel during upgradation of camel-api to 3.2 from 3.1.
>  
> Refer this [https://camel.apache.org/manual/latest/camel-3x-upgrade-guide-3_2.html]
> It seems that there is incompatibility with camel-restlet 3.0.0-RC2 along with Camel 3.2 and above.
>  
> One solution I can think of is revert the downgrade the Camel version to 3.1 instead of 3.4 which we would like to avoid.
> Please suggest what course of action can be taken for this issue with minimum impact or what is the compatibility of camel-restlet and other camel components.
