[rules-users] help! rule"rule_key" failed to predicate

I have seen this error before and doing this resolved the issue. >hello,everyone!I wrote a rule with Drools,but the error told me that the field Server.Message is not visible, I can't find how it happens. Please >help me, I am almost exhausted with it. thank you. >the rules are as follows: > >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");#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
