Hi, I don't understand how JBossRules is working with Date and Time constraints. I found that date format is something like "dd-MMM-yyyy" . Are there other formats that also include a time? How JBossRules is dealing with these time constraints? What are the functions used in rules to access the values of this constraints? I found this functions : utilService.dateWithin(someDate), utilService.UNIT_DAY. Are they some built in classes and methods that are used to access data types? where I could find some documentation to read about them ? Please explain this things to me! Kind regards, Oana. --------------------------------- Now that's room service! Choose from over 150,000 hotels in 45,000 destinations on Yahoo! Travel to find your fit.
