The Filter can filter a message using a filter strategy. A filter strategy returns a boolean value. Based on this value and the value of the inverse attribute, either the message is passed along, or is sent to the discard flow.

The filter can be used as a simple router service.

The filter strategy will have to be defined in a Bean.

In the table below, you will find an explanation of these properties. All attributes with a ‘*’ are mandatory.




By default, we fill this out with the technical ‘tag’, followed by a serial number. Changing the name is optional.


Set this value to true, if you want this service to be enabled.

Filter Strategy*

Reference to an implementation of a filter-strategy. This can either be a script or a bean implementing MyESBFilterStrategy. A script must return true or false.
