Hi, <div>What's the goal of that rule? </div><div>If you have a Driver called Jack you create a new Driver called TOTO.</div><div>Now you have two facts. </div><div>You can create a query in your DRL file like:</div><div>

<div>Check the documentation in the query section to see how to execute a query from java code.</div><div><br></div><div>Cheers</div><div class="gmail_extra"><br><br><div class="gmail_quote">On Tue, Dec 4, 2012 at 11:03 AM, Mister Nono <span dir="ltr"><<a href="mailto:noel.maurice@univ-jfc.fr" target="_blank">noel.maurice@univ-jfc.fr</a>></span> wrote:<br>

<br>
I have the drools rule (made in guvnor server) :<br>
<br>
<br>
1. | rule "driverRule"<br>
2. | salience 10<br>
3. | dialect "mvel"<br>
4. | when<br>
5. | Driver( driverAge : age > 18 && < 65 )<br>
6. | then<br>
7. | Driver fact0 = new Driver();<br>
8. | fact0.setName( "TOTO" );<br>
9. | insert( fact0 );<br>
10. | end<br>
<br>
<br>
... and the java code source :<br>
<br>
<br>
KnowledgeAgent agent =<br>
KnowledgeAgentFactory.newKnowledgeAgent("/Guvnor.properties");<br>
KnowledgeBase ruleBase = agent.getKnowledgeBase();<br>
<br>
StatefulKnowledgeSession workingMemory =<br>
ruleBase.newStatefulKnowledgeSession();<br>
<br>
Driver d = new Driver("Jack", 28, null);<br>
workingMemory.insert(d);<br>
<br>
workingMemory.fireAllRules();<br>
<br>
for(Iterator i = workingMemory.getObjects().iterator(); i.hasNext();)<br>
{<br>
Object obj = i.next();<br>
System.out.println(obj.getClass().getCanonicalName());<br>
<br>
if (obj instanceof Driver)<br>
{<br>
System.out.println("Driver name => " + ((Driver)obj).getName());<br>
System.out.println("Driver age => " + ((Driver)obj).getAge());<br>
}<br>
}<br>
<br>
<br>
But the drools rule changes the driver name "Jack" by "TOTO", but in the<br>
console the initial name "Jack" is always displayed.<br>
<br>
How to access at the objet who is in knowledge base (the modified objet) ?<br>
<br>
Thank. ;)<br>
<br>
