Hi I found that certain Classes in the old versions of rules has been removed and not define in the new versions as deprecated as java normally does. This results that the old version implementations can’t run with new versions of jboss rules without revising the implementation codes. I’d like to know the reasons for this type of approach. Thank you. --------------------------------- Now that's room service! Choose from over 150,000 hotels in 45,000 destinations on Yahoo! Travel to find your fit.
