4.10. Action scripts

Action scripts are pieces of code that define the Script property or an Element's interceptor action. They have access to globals, the Process variables, and the predefined variable kcontext. Accordingly, kcontext is an instance of ProcessContext class and the interface content can be found at the following location: Interface ProcessContext.
Currently, dialects Java and MVEL are supported for action script definitions. Note that MVEL accepts any valid Java code and additionally provides support for nested access of parameters, for example, the MVEL equivalent of Java call person.getName() is person.name. It also provides other improvements over Java and MVEL expressions are generally more convenient for the business user.

Example 4.3. Action script that prints out the name of the person

// Java dialect
System.out.println( person.getName() );

//  MVEL dialect
System.out.println( person.name );
