When executing a J2SE application which uses rules, the following exception is seen:
ilog.rules.res.session.IlrSessionCreationException: An error occurred while the rule session was created.:
ilog.rules.res.session.IlrSessionCreationException: ilog.rules.res.session, Message code: 10044
ilog.rules.res.util.IlrRemoteException: Missing "META-INF/default_ra.xml"
This error usually occurs if jrules-res-execution.jar is not packaged in your J2SE application.
Resolving the problem
When invoking rules in a J2SE environment, make sure you package executionserver\lib\jrules-res-execution.jar in your application, as detailed in the documentation under WebSphere ILOG JRules BRMS V7.1 > Rule Execution Server > Introducing Rule Execution Server > Rule Execution Server basics > Execution > Execution patterns
For detailed information on packaging applications for JRules, you can refer to WebSphere ILOG JRules Execution Server Packaging Applications.
Note: If this error occurs when using the JSR94 implementation in Rule Execution Server (RES), refer to the following document: Configuration of the JSR94 environment type and res_jsr94.conf file.
