i am trying to see if there is a way to not use java beans as fact

i have been looking to the MVEL website where they have a sample like 
this:

Map vars = new HashMap();
vars.put(x, new Integer(5));
vars.put(y, new Integer(10));

Integer result = (Integer) MVEL.eval(x * y, vars);
my question is if i use MVEL dialect, can i pass in a Map similar to 
the above for fact objects? Thanks.
Dialects make  no difference to  what you can assert. The dialect is 
simple the lanage used to execute returnValue, inlne-evals, evals and 
consequences. You can choose  Java or MVEL, or plugin your own.
