hey wolfgang,<br>
<br>
thanks a lot for your valuable and prompt help. it worked for me and
i'm able to run the rule engine with a spread sheet rule.<br>
for this, i'll be grateful to you.<br>
<br>
event resolved:<br>
<br>
actually "event" is imported and declared in the rule. the problem
is, in the then part when i referred the event object i forgot to
mention it with a preceding "$" symbol. and that was the culprit.
when i was going through the documentation, it said the "$" symbol
is not mandatory and it's optional.<br>
<br>
now i've found that, using the "$" symbol is optional. buf if you
use it on a variable declaration, it's mandatory that you've to
specify on further reference of that variable. today's findings...
:-)<br>
<br>
spreadsheet dependency:<br>
<br>
actually it worked for me without implementing any dependency in the
spreadsheet. probably i should educate myself in spreadsheet stuffs.<br>
<br>
<br>
thanks once again. <br>

Thanks for your quick response. I did as you say. now my
rule file when generated from excel sheet and printed in
console looks like this.<br>
<br>
package alertRouting;<br>
#generated from Decision Table<br>
import com.sify.beacon.events.RouteEvent;<br>
import com.sify.beacon.events.trapevent.Varbind;<br>
#From row number: 10
<div class="im"><br>
rule "210.210.122.100 GroupA"<br>
<br>
</div>
when<br>
$event : RouteEvent(nodeIp == "210.210.122.100")<br>
$varbind : Varbind(oid == "1.3.6.1.2.1.2.2.1.1"
&& value == "5")<br>
from $event.varbindings<br>
then<br>
event.setGroup("GroupA");<br>
System.out.println("set to Group A");<br>
<br>
end<br>
<br>
it seems that the "from" clause is in the next line as a
separate condition. so, drools have considered it as a
separate condition.<br>

"event" is the culprit. Now where is this "event"? Has it been
declared? Where? Perhaps a typo?...<br>

also, i don't understand about implementing the dependency

dependency conditions. sorry for my ignorance.<br>

This requires spreadsheet functions, e.g.<br>
=IF( D12="","","X" )<br>
would be in E12. The cell reference is relative, so copying it
dowm automatically changes D12 to D13, etc.<br>

In your case, you cannot have constraints with
parameters and "from" in the same column. You need 2
adjacent columns.<br>
<br>
CONDITION<br>
$varbind : Varbind<br>
oid == $1 && value == $2<br>
the pattern and constraints<br>
".1.3.6.1.2.1.2.2.1.1.0","5"<br>
----------------------------------------------------------------<br>
CONDITION<br>
<br>
from $event.varbindings<br>
the from clause<br>
x<br>
------------------------------------------------------------------<br>
<br>
Note the blank cell below CONDITION. The 'x' triggers
the insertion of the from clause. (It should be
possible to implement the dependency on the cell to
the left by a simple spreadsheet formula.)<br>
