Re: [rules-users] Reuse statless session

I might be putting too simplistic an interpretation on this, but this is what the Javadoc says for StatelessKnowledgeSession "StatelessKnowledgeSession provides a convenience API, wrapping StatefulKnowledgeSession. It avoids the need to call dispose(). Stateless sessions do not support iterative insertions and fireAllRules from Java code, the act of calling execute(...) is a single shot method that will internally instantiate a StatefulKnowledgeSession, add all the user data and execute user commands, call fireAllRules, and then call dispose()." So I'm not sure why you just wouldn't just directly use a StatefulKnowledgeSession instead of trying to re-use a stateless one. You can then update the Facts via their handles and update or retract and reinsert as needed.

In particlar I've seen unit tests creating a Stateless session in a @BeforeClass method, then this session was re-used across multiple tests methods "pushing" different data-sets into that unique session instance using commands (created with the org.drools.command.CommandFactory class).
