Convert it to XML on both sides. Drools 2 and 5 both support a xml input, for limited operators. Considering you are using 2.x you arent using anything that advanced.  Section 6.9 of the Drools 4 manual discusses the xml interface (works the same in 5). is the url. I'm sure you can find the drools 2 xml manual somewhere, but hopefully that will get you started.

Subject: [rules-users] drl 2.0 invoking drl 6.0

Anyone think of an obvious way for a fixed (legacy) install of a system running 2.x-era drools to pass control over to modern process (running drls 6).


Would want to pass the fact base across efficiently, but not the active rules/agenda state etc
