I wouldn't reuse a stateless session. You could reuse a stateful session and clean up between runs, but session creation is not that expensive. (and easily less expensive than cleanup of a stateful session, mattering on the complexity of your rules)<br>

My rule engine server is multi threaded.<br>
<br>
in the server main i build a knowledgebase:<br>
<br>
KnowledgeBuilderConfiguration config = KnowledgeBuilderFactory.newKnowledgeBuilderConfiguration(droolsConf, null);<br>
KnowledgeBuilder builder = KnowledgeBuilderFactory.newKnowledgeBuilder(config);<br>
builder.add(ResourceFactory.newFileResource("path to drools pkg", ResourceType.PKG);<br>
<br>
KnowledgeBase knowledgeBase = KnowledgeBaseFactory.newKnowledgeBase();<br>
knowledgeBase.addKnowledgePackages(builder.getKnowledgePackages());<br>
<br>
i have 10 threads that have the following code:<br>
<br>
<br>
<br>
thread run method:<br>
<br>
<br>
as long as a Vector has data do:<br>
<br>
1. StatelessKnowledgeSession droolsSession= m_droolsKagent.getKnowledgeBase().newStatelessKnowledgeSession();<br>
2. get data object from a vector<br>
3. create fact model from data<br>
4. droolsSession.insert(facts);<br>
5. droolsSession.fireAllRules();<br>
6. do stuff with the response<br>
7.droosSession.dispose<br>
8.get next object from vector.<br>
<br>
<br>
Questions:<br>
1. should i create each time the droolsSession? or can i resuse the same one, meaning can i create it in the Thread's constractor?<br>
<br>
Thanks<br>
Nadav.<br>
