hello,everyone! I wrote a rule with Drools, I compile the program and get the errors as follows:
[3,0]: [ERR 103] Line 3:0 rule 'rule_key' failed predicate: {(validateIdentifierKey(DroolsSoftKeywords.RULE))}? in rule
[3,9]: [ERR 101] Line 3:9 no viable alternative at input 'com' in rule package
[7,0]: [ERR 101] Line 7:0 no viable alternative at input 'import' in rule package in rule sample
I don't know how it happened, looking forward to your reply! thank you !!!
PS: My rules are here:
dialect "mvel"
package com.sampleimport 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
