----------------------------------

Claus,
I'll try to write a snippet, and will think about the camel-annotation.jar mechanism you suggest.
Will come back when done.

> Today TypeConverter detection is based on org.apache.camel.@Converter annotation.
> Allow user to override this by using meta-annotation. This can be useful to hide camel
dependencies, when extending the framework.
> ie, this can be done:
> package some.package.of.mine;
> @Retention(RetentionPolicy.RUNTIME)
> @Target({ElementType.TYPE, ElementType.METHOD })
> @org.apache.camel.Converter
> public @interface OwnConverterAnnotation {
> }
> import some.package.of.mine.OwnConverterAnnotation;
> @OwnConverterAnnotation
> public class FileToXXXConverter {
>     @OwnConverterAnnotation 
>     public static XXX toWorkflowEntry(File file) throws IOException {
>         return new XXX();            
>     }
> }
