[rules-users] How to retrieve the Rule names in the drools rule file

[Amila Silva]

hi Laun,
   I tries with your solutions but i couldn't find the way to configure the
meta - data part in rule file to read.
   I came across with following issues when trying to read it from a given
code.

  [12,2]: [ERR 102] Line 12:2 mismatched input 'AT' expecting 'then' in rule
"create new Instance"
   Exception in thread "main" java.lang.IllegalArgumentException: Could not
parse knowledge.

 i think this might be a issue with  a @ sign in the rule file but i think i
this kinda of annotations will help to specify the
 main rule name. Or is there any way to identify or filter out the main rule
name from file.

BTW your this solution help me a lot.
thanks
