Rule Engine work (Drools, Java)

I require assistance from a Drools/Java expert in loading domain-specific rules dynamically to allow for MANY rulebases to be loaded and run simultaneously. (i.e. must support multiple instances and rules must be stored either directly in database or on file system with paths stored in DBMS. The Java code must craete/load rules based on the data submitted from an AJAX form. The AJAX form is already complete...)
