Hi, > Couple of Questions: > a) What version of Websphere are you using

I decided to stop trying to get it to work ... then they have to deal with a simple editor to write rules (just a plain textarea in a website) ... there's a roadmap to migrate to WebSphere 6.1 but this could last months ... but i don't care anymore ... i'm just can use what's there ...
