[rules-users] Can I put java code in dslr file?

I want to convert my drl to dsl and dslr. I found that if I choose using dsl, I couldn't write java code in rules any more. I must translate everything in dsl file. Can I combine dsl and drl in dslr file, like below rule. when I am using dsl, I will get an error: "[10] Unable to expand: System.out.println("add caculation start");" rule "add caculation" agenda-group "add" no-loop true dialect "java" lock-on-active when $m: Whether exist event then System.out.println("add caculation start"); System.out.println("add caculation end"); end -- View this message in context: http://drools.46999.n3.nabble.com/Can-I-put-java-code-in-dslr-file-tp3578...
