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

Subject: [rules-users] ClassNotFoundException when using a function in a rule

Here is the exception:

Exception in thread "mythread" java.lang.NoClassDefFoundError: com/daxtechnologies/optima/fault/eventprocessor/NewEvent

Caused by: java.lang.ClassNotFoundException: com.daxtechnologies.optima.fault.eventprocessor.NewEvent

Here is my package code:

function void newEvent(ExtendedEventVO sample, String message) {

 System.out.println("Creating event:" + message);

}

rule "TestRule"

            dialect "mvel"

            when

            $e: ExtendedEventVO(); eval($e.getMsg().indexOf("TEHU1")>=0);

            then

            newEvent($e,"FIREEEE!!!!!");

end

I am using the web based jbrms and the RuleAgent to load the rules … I am getting the “Creating Event message on stdourerr ”,

Any ideas of what is wrong ?

Thanks
