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): org.drools.rule.DialectRuntimeRegistry; local class incompatible: stream classdesc serialVersionUID = 5308493362083281112, local class serialVersionUID = 2297533903900118816.
