6.2. API and Backwards Compatibility
Migrating to Version 6.1
In version 6.1, 5.x APIs are no longer officially supported.
Red Hat JBoss BRMS no longer provides backward compatibility with the rule, event, and process application programming interface (API) from JBoss BRMS 5. The content of the
knowledge-api JAR file is no longer supported in version 6.1 and is replaced by APIs contained in the kie-api JAR file that were introduced in JBoss BRMS 6.0.
If you used the legacy 5.x API (located in
knowledge-api.jar), please migrate (rewrite) the API calls to the new KIE API. Please be aware that several other APIs have changed between JBoss BRMS 5.x and JBoss BRMS 6.x, namely the task service API and the REST API.
Migrating to Version 6.0
The JBoss BRMS 6 system provides backward compatibility with the rule, event and process interactions from JBoss BRMS 5. You should eventually migrate (rewrite) these interactions to the all new revamped core API because this backward compatibility is likely to be deprecated.
If you cannot migrate your code to use the new API, then you can use the API provided by the purpose built
knowledge-api jar for backwards compatible code. This API is the public interface for working with JBoss BPM Suite and JBoss BRMS and is backwards compatible.
If you are instead using the REST API in JBoss BRMS 5, note that this has changed as well and there is no mechanism in it for backwards compatibility.
Where did the comment section go?
