[rules-users] Problem with Drools debuggin in Eclipse Reg:
Hi, I'm encountering a strange problem with debugging an Drools application in Eclipse Platform. I couldn't find any help in the internet. Also, i can't find any previous post in this mailing list. Please try to help me. My Platform details are below: OS: Fedora 13 Eclipse: Galileo Java: JDK 1.6 Update 21 Drools version: 5.1.1 Snapshot of the Error message: Console Output: ERROR: transport error 202: connect failed: Connection refused ERROR: JDWP Transport dt_socket failed to initialize, TRANSPORT_INIT(510) JDWP exit error AGENT_ERROR_TRANSPORT_INIT(197): No transports initialized [../../../src/share/back/debugInit.c:690] FATAL ERROR in native method: JDWP No transports initialized, jvmtiError=AGENT_ERROR_TRANSPORT_INIT(197) Event Details: Message: An internal error occurred during: "Launching DroolsTest (4)".

Re: [rules-users] decision table problem Reg:
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.

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.
DRL is free form, so line breaks don't matter.
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
"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.

please help me resolve this issue.

[rules-users] decision table problem Reg:
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.

Re: [rules-users] Drools Rule language resources Reg;
Hi,
Thanks for your prompt reply. Actually, I'm not into middle of
writing some rules. I'm working to implement Drools in a NMS
product. Where Root-Cause Analysis is done to identify the exact
problem in a network.
I'm initially working on a POC trying to identify pros and cons.
The approximate scenarios include
timing window
generating new co-related events
escalation, and so on
I'm not looking for a solution here. At least, I've not grown to
that extent in Drools. I'm expecting someone to guide me. Is the
resources I have is sufficient or is there some other resources
available elsewhere?
To be more precise, I want to the following
possible keywords in a .drl file
sematics
syntax, and
usage
Regards,
Murali Venugopal

Hi,
I'm a newbie to Drools and Rules. I see this Mailing list
provides lot of valuable information regarding Drools.
Actually I'm looking for some good resources which helps
in writing Rules. I.e Rule Syntax and Semantics. It's
since 3 months I have started showing interest in Drools.
But still I can't proceed more than the examples given in
the books, which is not sufficient to work on real time
projects.
I'm referring books like
1. Drools JBoss Rules 5.0
2. JBoss Drools Business Rules
also,
1. Drools documentation and Manuals.
But still there's no definitive guides for writing rules.
The Drools Documentation has listed all the possible
keywords. But, their Syntax and Semantics are missing.
I went through this entire Mailing List hoping someone
would have asked this question before me. But in vain.
So, please refer/point me some good resources for Rules.
Because in Drools, I believe, everything is possible only
through Rules.
