Hi Wolffgang,<br>
<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<br>
rule "210.210.122.100 GroupA"<br>
<br>
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>
<br>
the error message is <br>
<br>
error java.lang.RuntimeException: Rule Compilation error : [Rule
name='210.210.122.100 GroupA']<br>
alertRouting/Rule_210_210_122_100_GroupA_0.java (7:397) : event
cannot be resolved<br>
<br>
also, i don't understand about implementing the dependency to the
cell in left. i tried logical, mathematical dependency conditions.
sorry for my ignorance.<br>
<br>
please help me resolve this issue.<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>
