JavaScript
Camel supports JavaScript/ECMAScript among other Scripting Languages to allow an Expression or Predicate to be used in the DSL or Xml Configuration.
To use a JavaScript expression use the following Java code
import static org.apache.camel.builder.script.ScriptBuilder.*; ... ... javaScript("someJavaScriptExpression") ...
For example you could use the javaScript function to create an Predicate in a Message Filter or as an Expression for a Recipient List
