JESS: JSR-94 RuleExecutionSet and DTD

[Diesler,Thomas]

Hi,

 

I'm having trouble understanding how JSR-94 copes with execution sets that are distributed over more than one source.

 

This is how I do it:

 

      // do the basic setup

      ruleServiceProvider = new RuleServiceProviderImpl();
      ruleAdministrator = ruleServiceProvider.getRuleAdministrator();
      ruleExecutionSetProvider = ruleAdministrator.getLocalRuleExecutionSetProvider(null);
      ruleRuntime = ruleServiceProvider.getRuleRuntime();

 

      // create the execution set from an XML input stream
      RuleExecutionSet ruleExecutionSet = ruleExecutionSetProvider.createRuleExecutionSet(inStream, null);

      inStream.close();

 

      // here I would like to do something like

      ruleExecutionSet.addSomeMoreRules(inStream2);

      inStream2.close(); 

      // register the execution set & get the rule session
      ruleAdministrator.registerRuleExecutionSet(uri, ruleExecutionSet, null);

      ruleSession = (StatelessRuleSession)ruleRuntime.createRuleSession(uri, null, RuleRuntime.STATELESS_SESSION_TYPE);

 

      // execute the rules

      List resultList = ruleSession.executeRules(inputList);

Or, do I have to assemble my rules in one single XML source before I call createRuleExecutionSet?

 

The referrence implementation contains a number of example XML files, which differ in some aspects. Is there a DTD, or a more elegant way of specifying rules?

 

Thanks

Tomsk
