[jboss-dev-forums] [Design of JBoss ESB] - Supporting entry-point

Thu May 28 01:34:28 EDT 2009

We are intending to extend the BusinessRulesProcessor to support the entry-point  API, as part of the following task.

https://jira.jboss.org/jira/browse/JBESB-2273

We need to get a better understanding of what is possible as well as what needs to supported, and are intending to discuss this with the drools team at J1 next week.

In the meantime it would be good to get others opinions of what needs to be done, for example Jeff added the following comment to the JIRA.

There is a little more to this potentially than just configuring the names of a entry points in a single service. Entry points are relative to the StatefulKnowledgeSession. They allow for multiple event streams to populate the working memory. So for example the Order service could be configured to use the OrderStream, and a Customer service would be configured to use the CustomerStream. A third service would then be configured to create the StatefulKnowledgeSession and place this object in some location where it could be looked up and used to create the entry points by the other two services. This capability is perhaps not necessary as part of the Tech Preview, but should be kept in mind when designing the entry point logic.
