But as I have mentioned earlier we are using the JSR
calls and only one file we are loading. So directly we
are not loading the RuleBase class.
The rough code is provided below : Pls let me know
whether we can do something abt this.
RuleServiceProviderManager.registerRuleServiceProvider(
RULE_SERVICE_PROVIDER,
RuleServiceProviderImpl.class
);
RuleServiceProvider ruleServiceProvider =
RuleServiceProviderManager.getRuleServiceProvider(
RULE_SERVICE_PROVIDER );
ruleAdministrator =
ruleServiceProvider.getRuleAdministrator( );
// load the rules and register them
LocalRuleExecutionSetProvider ruleSetProvider =
ruleAdministrator.getLocalRuleExecutionSetProvider(
null );
InputStream rules =
this.getClass().getResourceAsStream( "Rules.java.drl"
);
RuleExecutionSet ruleExecutionSet =
ruleSetProvider.createRuleExecutionSet( rules, null );
ruleAdministrator.registerRuleExecutionSet(
"Rules.java.drl", ruleExecutionSet, null );
RuleRuntime ruleRuntime =
ruleServiceProvider.getRuleRuntime( );
statelessRuleSession = ( StatelessRuleSession )
ruleRuntime.createRuleSession("Rules.java.drl",null,
RuleRuntime.STATELESS_SESSION_TYPE );
List outList = statelessRuleSession.executeRules(
inList );
