hi,
i'm facing a problem with decision tables. i've got a .drl working file.
but when i happen to take that into a .xls file ( decision table ) it
throws some errors.
my actual rule in .drl file has got something like this.
when
$event : RouteEvent( nodeIp == "192.168.1.12 )
$varbind : Varbind ( oid == ".1.3.6.1.2.1.2.2.1.1.0" && value ==
"5" ) from $event.varbindings
then
System.out.println("some text")
here in my decision table, my first cell would have the first condition
$event : RouteEvent
nodeIp == "$param"
that is, i've to omit my "(" and ")" braces.
so now, my second condition is
$varbind : Varbind
( oid == "$1" && value == "$2" ) from $event.varbindings
here i don't know how to omit the "(" and ")" braces. or should i
add
and other layer of those braces.
anyway, the decision table is not working, where as my rule file does.
the error message is
error java.lang.RuntimeException: [10,55]: [ERR 102] Line 10:55
mismatched input 'FROM' expecting ')' in rule "210.210.122.100
GroupA"
in pattern Varbind[10,77]: [ERR 102] Line 10:77 mismatched input ')'
expecting 'then' in rule "210.210.122.100 GroupA"
my doubt is,
in the first case all my condition expression is contained with in
braces. where as in second case, it's not. so how do i've to handle
this. do i've have to omit the braces in the second case or not.
please help me. i've been struggling to solve this error. also, i
couldn't find references in the documentation.
thanks in advace.

Hi Wolffgang,
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.
package alertRouting;
#generated from Decision Table
import com.sify.beacon.events.RouteEvent;
import com.sify.beacon.events.trapevent.Varbind;
#From row number: 10
rule "210.210.122.100 GroupA"
when
$event : RouteEvent(nodeIp == "210.210.122.100")
$varbind : Varbind(oid == "1.3.6.1.2.1.2.2.1.1" && value ==
"5")
from $event.varbindings
then
event.setGroup("GroupA");
System.out.println("set to Group A");
end
it seems that the "from" clause is in the next line as a separate
condition. so, drools have considered it as a separate condition.
the error message is
error java.lang.RuntimeException: Rule Compilation error : [Rule
name='210.210.122.100 GroupA']
alertRouting/Rule_210_210_122_100_GroupA_0.java (7:397) : event
cannot be resolved
also, i don't understand about implementing the dependency to the cell
in left. i tried logical, mathematical dependency conditions. sorry for
my ignorance.
please help me resolve this issue.

DRL is free form, so line breaks don't matter.
the error message is

alertRouting/Rule_210_210_122_100_GroupA_0.java (7:397) : event cannot

"event" is the culprit. Now where is this "event"? Has it been
declared?
Where? Perhaps a typo?...
also, i don't understand about implementing the dependency to the cell in
left. i tried logical, mathematical dependency conditions. sorry for my
ignorance.
This requires spreadsheet functions, e.g.
=IF( D12="","","X" )
would be in E12. The cell reference is relative, so copying it dowm
automatically changes D12 to D13, etc.

hey wolfgang,
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.
for this, i'll be grateful to you.
event resolved:
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.
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... :-)
spreadsheet dependency:
actually it worked for me without implementing any dependency in the
spreadsheet. probably i should educate myself in spreadsheet stuffs.
thanks once again.

now i've found that, using the "$" symbol is optional. buf if you use it
on
a variable declaration, it's mandatory that you've to specify on further
reference of that variable. today's findings... :-)
In Java, '$' is valid in identifiers, just like a letter or '_'. Docs
explain that using the dollar sign may help you to distinguish between bound
variables and field names.
