Could some one give some input for the following questions<br>
1) Can drools read the datas for facts from Excel<br>

Use a 3rd party library like XLSBeans:<br>

<blockquote type="cite"><font face="Courier New, Courier, monospace">2) is Nested rules is supported in Drools<br>
</font></blockquote>
There 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.<br>
<blockquote type="cite"><font face="Courier New, Courier, monospace">3) can rules communicate across .drl files<br>
</font></blockquote>
rules do not communication, they match data and fire rules. <br>
<blockquote type="cite"><font face="Courier New, Courier, monospace">4) is there support for looping and collection<br>
</font></blockquote>
Drools 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.<br>
