Java + Groovy

The default most configurations and implementations are prepared in Apache Camel routes via XML DSL. But sometimes is needed to prepare own implementation of the Processor in Camel or some helper beans. For this is needed to know standard Java.

For some complex data manipulation, transformation can be used also instead of pure Java language the Groovy language.

This is the reason why each integration engineer has to know standard Java (Java 11 and higher) and Groovy language and have practical experiences from the previous projects
