Hi All,
I have a snaphot URL as :
http://localhost:8080/drools-jbrms/org.drools.brms.JBRMS/package/org.acme...
.
I configured above URL in one propertied file and accessing in one class i
written flollowing code in the class that iam going to execute.
private static RuleBase loadRuleBaseFromRuleAgent() {
RuleAgent agent = RuleAgent.newRuleAgent(
"/brmsdeployedrules.properties" );
RuleBase rulebase = agent.getRuleBase();
return rulebase;
}
*But iam getting following error :*

SB,
Came across this a while back. I *think* the quickest fix is to update
any Drools Jars (that exist *within* the Web / War insurance sample) and
make sure they are the same versions as that of the BRMS that you are using.

New subject: ClassNotFoundException when using a function in a rule
Switched from java 1.6 to java 1.5 and I don't have the problem anymore . So I guess
there is some issue with functions and java 1.6 in release 4.0.4
