Re: [rules-users] unable to create field extractor for tickerId
"Unable to create FIeld extractor", mostly that is because you did not
declare getters and in your java class.
Drools uses the getters to extract the needed values.
Make sure you use the correct naming conventions as well. I.e. public int
getTicketId(){...}
