The trace indicates there is an attempt to connect to a DB running on your local. I doubt Drools is trying to connect to a DB, unless you have objects in your rules that access DB. It looks like you are getting this error while deploying a webservice that happens to use Drools Expert jars. it is possible that this is coming from your application code and not Drools. I see you have another post on Guvnor 5.5 and Weblogic 11. I had no success with that either. I had a similar post and didnt get any response. so, I doubt anybody has done that succesfully. WLS 11 is jee5 and does not support CDI. Even with WLS 12 (jee6), I couldnt as there seems to be conflicts with wls and weld cdi implementations. I'll watch your other post to see if anybody responds as I am curious as well. -- View this message in context: http://drools.46999.n3.nabble.com/How-to-deploy-drools-5-5-on-weblogic-in...
