Hello:Use a 3rd party library like XLSBeans:
Could some one give some input for the following questions
1) Can drools read the datas for facts from Excel
2) is Nested rules is supported in DroolsThere are many ways to achieve the same effect. Use mail-archive and search the user mailing list and you'll read lots about ruleflow, agendagroups, semaphores etc.
3) can rules communicate across .drl filesrules do not communication, they match data and fire rules.
4) is there support for looping and collectionDrools has the most advanced LHS syntax than any other engine. with support for both collect and accumulate with accumulate functions - look into those. Any valid Java or MVEL statement can be used for the RHS.
Thanks in advance,
Ravi
