[jboss-user] [Beginners Corner] - [Jboss Rules] - using constraints in LHS
I am discovering jboss rules (drools 4.0.7). I try to reproduce the example
'State' of drools.
The drools version works fine.
But in my version, the rules are not fired and I do not understand why .... It is so basic
I do not see where my mistake is. Please help
the rule
| package examples.statemachine
|
| import com.corp.drools.examples.statemachine.State;
|
| rule Bootstrap
| when
| a : State(name == "A" )
| then
| System.out.println(a.getName() + " finished" );
| a.setState( State.STATE_FINISHED );
| end
|
the class State
| public static final Integer STATE_NOTRUN = new Integer(0);
| public static final Integer STATE_FINISHED = new Integer(1);
|
| public State(final String name) {
| this.name = name;
| this.state = State.STATE_NOTRUN;
| }
|
| private String name;
| private Integer state;
| // ... getter, setter
|
the test case :
| public void test2() throws Exception {
| final PackageBuilder builder = new PackageBuilder();
| builder.addPackageFromDrl(new InputStreamReader(
|
this.getClass().getClassLoader().getResourceAsStream("examples/statemachine/rules.drl")));
|
| RuleBase ruleBase = RuleBaseFactory.newRuleBase();
| ruleBase.addPackage(builder.getPackage());
| StatefulSession session = ruleBase.newStatefulSession();
|
| WorkingMemoryConsoleLogger logger = new WorkingMemoryConsoleLogger(session);
|
| State[] objects = new State[] { new State("A") };
| session.insert(objects[0]);
| session.fireAllRules();
|
| session.dispose();
| Assert.assertEquals(State.STATE_FINISHED, objects[0].getState());
| }
|
the test case output :
OBJECT ASSERTED value:A-0 factId: 1
