3.8. Configuring an MVEL ruleBase

  1. To configure an MVEL ruleBase, see the code below: 
    <?xml version="1.0"?>
<smooks-resource-list  xmlns="http://www.milyn.org/xsd/smooks-1.1.xsd"  xmlns:rules="http://www.milyn.org/xsd/smooks/rules-1.0.xsd">
 
    <rules:ruleBases>
        <rules:ruleBase name="order" src="/org/milyn/validation/order/rules/order-rules.csv" provider="org.milyn.rules.mvel.MVELProvider"/>
    </rules:ruleBases>
 
</smooks-resource-list>
  2. You must store your MVEL rules in CSV files. The easiest way to edit these files is through a spreadsheet application such as LibreOffice Calc or Gnumeric. Each rule record contains a rule name and an MVEL expression.
  3. If you wish to create comment and header rows, prefix the first field with a hash (#) character.
