Hi, I've fixed this bug in the trunk few days ago: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.

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. Stack trace should follow.
