PS: My rules are here: dialect "mvel" package com.sample import com.sample.Server; rule "system will execute 'tc' command" when eval(Server.Message>8388608) then System.out.println("The network is so crowd that it needs repairing."); Runtime.getRuntime().exec("tc");#give the authority and execute the "tc" command end rule "caution" when eval(Server.Message==8388608) then System.out.println("caution!The network maybe will get blocked very soon."); end rule "fluent network" when eval(Server.Message<8388608)#conditions then System.out.println("the current network is very good");#actions end _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
