We have been packaging RHBA as business-central.war, which requires the following change in standalone.xml file in order to have communication between Kie Server and Business Central work out-of-the box, after they have been deployed without changing their default names.

<property name="org.kie.server.controller" value="http://localhost:8080/decision-central/rest/controller"/>

should be changed to:

<property name="org.kie.server.controller" value="http://localhost:8080/business-central/rest/controller"/>

Otherwise, the communication between Kie Server and Business Central will be broken upon deployment, if manual tweaking is not performed.
