### Java or CTL

Transformations can be written in Java or Clover transformation language (CTL):

- Java can be used in all components.

  Transformations executed in Java are faster than those written in CTL. Transformation can always be written in Java.

- CTL cannot be used in JMSReader, and JMSWriter.

  Nevertheless, CTL is very simple scripting language that can be used in most of the transforming components. Even people who do not know Java are able to use CTL. CTL does not require any Java knowledge.
