[rules-users] Rules integration with Java -need help

[Pavel Tavoda]

Just look to Properties documentation. You can set property from java
too. Something like:
Properties properties = new Properties();
properties.load(new FileInputStream(module2PropertiesFilePath));
properties.setProperty("url", "http://MyURL...")
RuleAgent agent = RuleAgent.newRuleAgent(properties);
....
