[jboss-user] [Beginners Corner] - drools & jbrms client

[furit]

I'm writing a java class calling a package deployed into jbrms.

The code of the client class is the following

                ......
		InputStream s = new FileInputStream(new File(FILE_PROP));
		prop.load(s);
		RuleAgent agent = RuleAgent.newRuleAgent(prop);
		RuleBase rb = agent.getRuleBase();
                ......

But when the last row is executed I get the following exception

java.lang.ClassNotFoundException: [className]
