Ugh this was hidden, but yes you can actually do this now. Here is small example:

StatelessKnowledgeSession ksession = kbase.newStatelessKnowledgeSession();
Person p = new Person(); // some dummy fact for this test
RuleNameEndsWithAgendaFilter filter = new RuleNameEndsWithAgendaFilter("TEST");

@SuppressWarnings("rawtypes")
List<Command> cmds = new ArrayList<Command>();
cmds.add(CommandFactory.newInsert(p));
cmds.add(new FireAllRulesCommand(filter));

ExecutionResults results = ksession.execute(CommandFactory.newBatchExecution(cmds));

This will only execute rules that end with "TEST"



The Agenda Filter is defined as:

private static class RuleNameEndsWithAgendaFilter implements AgendaFilter {
		private final String suffix;

		private final boolean accept;

		public RuleNameEndsWithAgendaFilter(final String suffix) {
			this(suffix, true);
		}

		public RuleNameEndsWithAgendaFilter(final String suffix,
				final boolean accept) {
			this.suffix = suffix;
			this.accept = accept;
		}

		public boolean accept(final Activation activation) {
			if (activation.getRule().getName().endsWith(this.suffix)) {
				return this.accept;
			} else {
				return !this.accept;
			}
		}
	}

> It is currently not possible to use AgendaFilter with a  stateless session. It would be nice if the stateless session execute method would also be able to take in the agendafilter argument just like fireAllRules does.
