When executing my rules deployed on the Business rules service on Bluemix, I see the following exception:
ilog.rules.res.session.IlrSessionCreationException: An error occurred while the rule session was created: com.ibm.rules.res.xu.internal.XUException: It was not possible to retrieve ruleset information: /MyRuleApp. ilog.rules.res.persistence.IlrDAOException: Wrong path used:"/MyRuleApp". ilog.rules.res.session.IlrJ2SESessionFactory.createStatefulSession(IlrJ2SESessionFactory.java:125) ilog.rules.res.session.impl.IlrSessionFactoryBase.createStatefulSession(IlrSessionFactoryBase.java:158) com.ibm.rules.htds.DecisionServiceController.getStatefulSessionBase(DecisionServiceController.java:163) com.ibm.rules.htds.servlet.RESTDecisionServiceServlet.onMessage(RESTDecisionServiceServlet.java:836) com.ibm.rules.htds.servlet.RESTDecisionServiceServlet.handleRequest(RESTDecisionServiceServlet.java:750)
I had specified an incomplete URL for the REST POST request for the rule service, which did not specify the path to the ruleset:
https://brsv2-12345678.ng.bluemix.net/DecisionService/rest/MyRuleApp
Once I updated the URL to point to the RuleApp version and ruleset version, the POST request executed successfully:
https://brsv2-12345678.ng.bluemix.net/DecisionService/rest/MyRuleApp/1.0/myrules/1.0
