[rules-users] RuleAgent question

[surya_n2007]

You can provide the properties to the Rule agent by using properties file or
java.util.properties.I am using java properties object and creating rule
agent by specifying the below properties.Created rule base and caching
rulebase.

                        Properties dynamicRueProperties = new Properties();	
		dynamicRueProperties.setProperty("name", "SampleRuleAgent");
		dynamicRueProperties.setProperty("dir",
"C:/Project/Workspace/DroolsTest/rules");
		dynamicRueProperties.setProperty("file",
C:/Project/Workspace/DroolsTest/rules/file.drl");	
		dynamicRueProperties.setProperty("localCacheDir",
"C:/Project/Workspace/DroolsTest/dump");
		dynamicRueProperties.setProperty("poll", "30");
		dynamicRueProperties.setProperty("newInstance", "false");
RuleBase ruleBase = null;
RuleAgent ruleAgent = null;
ruleAgent = RuleAgent.newRuleAgent(ruleProperties); 


Cache using ur own technique i am using hashmap.....
cacheRuleBaseMap.put("OWN_RULEBASE",ruleAgent.getRuleBase());
ruleBase = cacheRuleBaseMap.get("OWN_RULEBASE");
ruleBase.newStatefulSession();

I am having problem to add DSL to the rule agent.

Thanks & Regards
Surya.
