Hi, I have the following bean and trying to run "accumulate" to get the average of CPU usage from a cluster. public static class cpuTracker{ private String machinename; private String averageCPU; } My rule is as follows. rule check when $aggr : Number() from accumulate(cpuTracker($avg : Integer.parseInt(averageCPU.split("\\.")[0])), average($avg)) then System.out.println(" Average value : " + $aggr); end If the averageCPU is an integer type then accumulate works fine but my problem is that it is string type and I am trying to convert it to integer from a rule file and it throws a bunch of compile time errors. any help in resolving it or some workaround is highly appreciated. -- View this message in context: http://drools.46999.n3.nabble.com/using-CE-accumulate-tp3662339p3662339.html Sent from the Drools: User forum mailing list archive at Nabble.com. _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
