This component is used for executing BeanShell Scripts. The BeanShell script to be executed is specified using the Custom Property Sheet (CPS). This component executes the script on documents it receives as input and returns the result.

Icon

The component uses the document object to get the content and properties of the message. The result after executing of the script should be set back onto the document object.

Useful Tips

  • Input message content and properties can be accessed using document object. For example, 'document.getText()' returns input message content. To access a message property named 'TestProperty, 'document.getRecord().getProperty('TestProperty')' returns the value of the property.
  • Message properties can be set using 'setProperty' method.
  • Message properties which are set on input message also appear on output message unless they are changed in the script. For example, if a property named 'TestProperty' is present on input message then output message also contains the property unless it is changed in script provided.
  • If there is no return value in the script, input record is sent as output message with empty message content.

  • The component uses the document object to get the content and properties of the message. The result(return value) after executing the script is set as output message.
