[rules-users] Using GUVNOR for FUSION RULES

[Michael Anstis]

Sure.

   - Create "New Rule"


   - Add a condition (green + near "WHEN")


   - Select "From Entry Point"


   - Type "lowLevelSensorStream" into TextBox


   - Click on "click to add patterns..."


   - Select your Fact Type (see * below)


   - In "Over sliding window" ListBox select "Length"


   - Type "1" into the TextBox next to "Length".

* OK, so this is possibly where you're having problems.

In order for a Fact Type to be used with CEP it needs to be annotated as an
Event. This is how this can be accomplished:-

*If you have a Declarative Model
*

   - Open the Declarative Model


   - Select the Fact Type that should be an Event


   - Add an Annotation, name="role", key="value", value="event"


   - Save


*If you have a POJO Model*

   - Create a new Declarative Model


   - Add a Fact Type that matches the name of that in your JAR


   - Add an Annotation, name="role", key="value", value="event"


   - Save


Annotating your POJO is covered in the Drools Expert User Guide. You are
just using Guvnor to achieve what is required.

With kind regards,

Mike
