5.2. Annotations in Data Modeler

Red Hat JBoss BRMS supports all Drools annotations by default, and can be customized using the Drools & jBPM domain screen. For further information about available domain screens, see Section 5.5, “Data Object Domain Screens”.

If you want to add/edit custom or pre-defined annotations, you can switch to the source tab and modify the source code directly (in Red Hat JBoss Developer Studio or Business Central). You can also use the Advanced screen to manage arbitrary annotations.

When creating or adding fields to a persistable data object, the JPA annotations that are added by default will generate a model that can be used by Red Hat JBoss BRMS at runtime. In general, modifying the default configurations where the model will be used by processes is not recommended.

Red Hat JBoss BRMS 6.2 onwards supports the use of JPA specific annotations, with Hibernate available as the default JPA implementation. Other JPA annotations are also supported where the JPA provider is loaded in the classpath.

Note

When adding an annotation in the Data Modeler, the annotation class should be on the workbench classpath, or a project dependency can be added to a .jar file that has the annotation. The Data Modeler will run a validation check to confirm that the annotation is on the classpath, and the project will not build if the annotation is not present.
