You could take a look at drools-templates, and relevant sections in the user guide, as a starter.

If that does not cover your requirements take a look at drools-templates source code on github.

Alternatively have a look for MVEL templates on Google (other search engines are available).

With kind regards,

I came to know through drool user forum that a drl file can be created using
recursive MVEL 2.0 template.
I am trying like below.

public static String prepareRule(String RuleName){
                String template = "\n rule \""+RuleName+"\" "+
                                  "\n dialect \"mvel\" "+
                                  "\n salience \"10\" " +
                                  "\n when" +
                                  "\n demo : Demo( one == \"N\" , two == \"C\" , three == 1005 )" +
                                  "\n then" +
                                  "\n demo.setFirst( 4003 );" +
                                  "\n demo.setLast( 4003 );" +
                                  "\n demo.setRuleID( \"SEQ_1\" );";
                return template;
        }

public static String getRuleAsString(String template){
                Map vars = new HashMap();
                return (String) TemplateRuntime.eval(template,vars);
        }

public static void main(String[] args) {

                System.out.println(getRuleAsString(prepareRule("Rule 1")));
        }

When i am printing it out, It is generating rule skeleton. I am planning to
create whole rule stuff passing arguments like rule name in the example. Am
i doing correct?
How to do it correctly?
