Hi, I've fixed this bug in the trunk few days ago:
https://jira.jboss.org/browse/BRMS-320
<https://jira.jboss.org/browse/BRMS-320>The bug is still open because I don't
have enough permissions in jira yet. ;)
Please try it out and let me know the results.
Best,

Hi All, I am just trying to call the package created in the Guvnor using sample java class
by loading from the properties. As below : public static final void main(String[] args) {
System.out.println("Mainnnnnnnnnn"); Properties properties = new Properties();
try { properties.load(new FileInputStream("Guvnor.properties")); } catch
(IOException e) { } RuleAgent agent = RuleAgent.newRuleAgent(properties); RuleBase
ruleBase = agent.getRuleBase(); WorkingMemory workingMemory =
ruleBase.newStatefulSession(); GuvnorModel gm=new GuvnorModel(); gm.setAge(22);
workingMemory.insert(gm); workingMemory.fireAllRules(); for (Iterator i =
workingMemory.iterateObjects(); i.hasNext();) {
System.out.println(i.next().getClass().getCanonicalName()); } } // and got the following
error : RuleAgent(default) EXCEPTION (Sun Apr 04 15:38:12 EDT 2010):
