Task Server as Jboss Service
by Cristiano Nicolai
Hi guys,
I think that would be great if we could deploy the TaskServer
(MinaTaskServer) as a JbossMC bean, making possible to administer it using
admin-console.
There's any work in this way or other plans to deploy this component?
Thanks.

Repackaging of the jar: missing drools.rulebase.conf?
by drdaveg
I had several Eclipse projects with customized WorkItem's in 5.1. The latest
download of the source code seems to have been reorganized: I see
drools.rulebase.conf files that seem unrelated to drools.workDefinitions and
all the versions that look like what I would expect are in the example files
and their jars; have the drools-process jar's been repackaged without
drools.rulebase.conf or might this file have been deprecated?
What I had been expecting was to find an entry like:
drools.workDefinitions = WorkDefinitions.conf
in the file with a corresponding WorkDefinitions.conf file for the email and
log WorkItem's. Thanks!

Re: [rules-users] Rules in App Server Error
by Greg Barton
My, aren't we snippy?
OK, well if you read this then note that those rules shouldn't work in any environment for the reason previously stated. (Use of an undeclared variable in the RHS.) If they are working then something odd is going on, and since you say they are then...something odd is going on.
BTW, the error you're getting now is an mvel error:
http://mvel.codehaus.org/Strong+Typing+Mode
Since you're currently getting it for "$severity" and not just "severity" even though the former does not currently appear in your rule...well that's the odd bit I mentioned before. Somewhere $severity (along with $weight, $factor, and $tempScore) is being declared, but it's not in the text of the rule as you've provided it.

Subject: Re: [rules-users] Rules in App Server Error that's weird.. you are using a varible that you never define in the Right Hand Side.
$severity was never defined. In the RHS remember that you can write pure java. So if you want a variable called severity you should declare it as:

KnowledgeAgent exception while trying to deserialize KnowledgeDefinitionsPackage
by John Peterson
I'm getting the following error when I attempt to run my Drools
application. I recently upgraded from Drools 5.0.1 and Guvnor 5.0.1 to
5.1.1 (for both). I've looked through the rules-users list and I found
the issue with the XML Change Set (authentication), which I've addressed
(XML listed at the bottom), but I'm still getting the error. Does
anyone have any ideas or can point me in a particular direction?
Thanks

Rules in App Server Error

Using Guvnor fact models for Eclipse rule editing
by flo
Title says almost all, if I check out my already created Models, Rules and
Enumerations from Guvnor to an Eclipse Project, I can edit them all, but
Eclipse's guided business rule editor doesn't seem to recognize my Fact
Model drls which are located in the same folder.
Strangely, the enums are recognized correctly and can be used in the guided
editor...But if I try to add a fact to the LHS (or a fact property) for
example, the resulting list to choose from has no entires beside the
standard "...".
I've already tried a variety of "import" statements in the autocreated
"drools.package" file, but this didn't seem to make any change. Do I need to
make any settings on the project, or do the namespaces between guvnor and
eclipse have to match or something like that?
As a short explanation what I'm actually trying to achieve - I have a Guvnor
repository, which is used in conjunction with drools-server and a .NET
client (no Java application anywhere!). This repository already contains my
Fact Model as DRLs, and also some enums and some rules. For authoring
additional rules, I don't want to use the Guvnor web interface but eclipse
because of its far better usability when handling lots of rules...now this
obviously doesn't work without Eclipse recognizing my fact model.
Thanks for any advice on this!
Best,
phlo

"==" not work for big int value
by Zeke
Hi,
I'm using Drools 4.0.7. I find "==" operator does not work for big int
value (like 2147483647). The condition is like "sec.fir.i == 2147483647". I
attach my test code. With my simple testing, it seems that it does not work
for comparsion with int constant from 1000000001 to 2147483647. Is it a bug
of drools? I have already tested long and BigInteger do not have this kind
of problem.
Thanks!
