Drools Execution Server - SOAP Support / XML Format
by Miguel Fernando Cabrera
Hello to all,
Right now I am testing Drools Execution Server 5.1.1
I already made it work with Jboss and ran the test using the restful
interface (I used the Poster firefox extension).
Now I was checking if I could create a SOAP Service. On the documentation
is not even mentioned [1] . So I kept looking. On the Weblog of Lucas
Amador, I found this article[2] (it was written some months ago but compared
to the documentation it looks updated) and it says:
"If you want to have SOAP support, you need to create your custom Drools
Policy." (Whathever that means).
However, I see some example of Soap endpoint "out-of-the-box" in this post
of Salaboy [3]. I tried to reproduce those configuration but I failed to do
so because it on the webpage showing the available services
(in my case http://localhost:8080/drools-5.1.1-server/kservice/ ) the Soap
endpoint never shows up.
Here is the camel-server.xml (http://pastebin.com/Hf0yvNHQ) and the
knowledge-services.xml (http://pastebin.com/jqrUS9aK). They are both very
basic, they are small modification to the default ones.
So, rounding up, my question is, does Drools Execution Server 5.1.1 supports
Soap endpoints? if so, based on the configuration files what am I doing
wrong?
And additional question is, where I can find the XML serialization format.
For example, when using the test that comes with drools-server (REST end
point) I sent the following xml:
<batch-execution lookup="ksession1">
<insert out-identifier="person1" return-object="true">
*<org.test.Message>*
* <text>Wepaje</text>*
* </org.test.Message*>
</insert>
</batch-execution>
What if for example org.test.Message contains other complex object (with
properties and so on). How the XML should look like?
Thanks in advance for your help

Drools planner & Scala
by Adam Warski
Hello,
I'm using Planner in a Scala program and it almost works without problems; the only one is in implementing the Solution interface, as it uses raw (erased) version of Score, which is normally generic (Score<S extends Score>). Scala generally doesn't like raw types and in most cases it's impossible to extend/implement interfaces which use them. A work-around is to introduce an "adapter" in Java, which you can later extend in Scala:
public abstract class ScalaSolution implements Solution {
public Score getScore() { return getScoreScala(); }
public abstract Score<?> getScoreScala();
public void setScore(Score score) { setScoreScala(score); }
public abstract void setScoreScala(Score<?> score);
}
and then in Scala:
class Schedule(...) extends ScalaSolution {
var score: Score[_] = _
def setScoreScala(score: Score[_]) = { this.score = score }
def getScoreScala = score
...
}
So the fix is to replace the raw Score type with Score<?>. Maybe it would be possible to apply that in the code? I tried it locally and it compiles without problems.
And a side question: do you have any plans on implementing multithreading in planner? So that several moves could be explored concurrently? I saw there's an open Jira issue for some time, but it didn't have any timeframe information.

Re: [rules-users] How to modify changeset.xml in guvnor
by kenichiwa
Maybe this will clarify things....
For this code:
...
...
...
String urlString =
"http://localhost:9080/drools-guvnor/org.drools.guvnor.Guvnor/package/defa...";
URL url = new URL(urlString);
KnowledgeAgent kagent =
KnowledgeAgentFactory.newKnowledgeAgent("TestAgent");
UrlResource urlResource = (UrlResource)ResourceFactory.newUrlResource(url);
urlResource.setBasicAuthentication("enabled");
urlResource.setUsername("admin");
urlResource.setPassword("");
kagent.applyChangeSet(urlResource);
KnowledgeBase kbase = kagent.getKnowledgeBase();
...
...
...
I am getting this exception:

Problem persisting human tasks
by raic
Hi,
I'm having problems using drools flow persistance with human tasks. I'm
using drools server.
On one hand, I have my test application, which starts a MinaTaskServer for
registering human tasks, and then, the application generates JSON commands
for executing a flow with human tasks on the execution server.
Without using flow persistence, this is working ok, i'm able to retrieve the
pending tasks and completing them without problems.
When I try to configure flow persistence on the execution server, i can
start the process, the tasks are registered ok and drools flow tables are
generated in my database (processinstanceinfo,sessioninfo,workiteminfo...)
with the correct flow information. The problem appears when i retrieve a
pending task, and then, i want to complete it. It seems that the
communication between MinaTaskServer and ExecutionServer is not ok.
The error i'm getting is the following:
[2010:11:327 18:11:661:debug] Message receieved on client :

How to specify relative URL in chagenset.xml file
by Pardeep Ruhil
Hi,
I am getting File Not Found Exception when I try to give relative path of the file.
<resource source='file:../HelloWorld.drl' type='DRL' />
But when I give the complete path, It picks the changeset.xml file.
<resource source='file:C:/Tomcat/webapps/DroolsCheck/HelloWorld.drl' type='DRL' />
Please tell me the syntax for using the relative path for my workflow or rule files.
Thanks & Regards
Pradeep Ruhil

taskService restart problem (urgent response needed)
by KiranP
i m having 2-3 tasks in my flow the flow works fine in the normal conditions
the tasks are handled by the MinaTaskServer and MinaTaskClient but the
problem is that it uses the command and the call back mechanism using the
map of tasks request (if i m not wrong) hence when the taskservice restarts
all the callback refrence is lost and completing any task wont updated to
the MinaTaskServer (even if the task is available)
can any one hint me who i can achieve trans-restart task completion.....
till today none of my posts got a reply..............i think u r all
busy............if some one gets time plz help....
bcoz now it has become a grave matter.........it urgent...
thanks

Re: [rules-users] Drools 5.1: What happens when an incremental KA rebuild fails?
by Esteban Aliverti
I will check this problem. I'll need to create a test scenario first.
Which version of drools are you using? Does the error still occurrs if you
point to the drl instead of the directory?
Best regards!
El ene 14, 2011 5:14 p.m., "ljnelson" <ljnelson(a)gmail.com> escribió:
Seeing some strange things on a production system.
I have Drools set up to use a KnowledgeAgent.
I have the KnowledgeAgent set up to scan resources and directories.
The agent is pointed at--let's say--C:\LEAD\rules, where "LEAD" is the name
of the project in question and "rules" is a directory underneath which I
would like to have several .drl files.
I begin by placing one well-known, valid .drl file under there. That
obviously loads up fine and the rules go into effect.
If I deliberately introduce a syntax error, I hear about it in the
logs--that's fine too.
But if I then remove the syntax error, it's as though scanning stops. The
KnowledgeAgent appears as though it is never rebuilt again, so it appears
simply to be broken.
I will obviously supply more details as needed, but thought I'd fire this
quick flare to see if anyone knows of any simple cause here.
Best,
Laird

Declaring events separately from rules breaks expires
by Samuli Saarinen
Hello,
I have the following situation with Drools 5.1.1: 2 drl files where one
contains an event declaration:
declare Event1
@role(event)
@expires(1s)
end
and other has a simple rule:
rule "Evt1"
when
e: Event1(value == 10)
then
System.out.println(e);
end
And I have the following test which fails:
ses.insert(new Event1(1));
ses.fireAllRules();
clock.advanceTime(2, TimeUnit.SECONDS);
ses.fireAllRules();
assertEquals(ses.getFactCount(), 0L);
The same test passes if the rule and event declaration are on the same
drl file.
Further more if I declare the event in both of the files with different
@expires the one being used is the one that is added first. I was hoping
that the first declaration to be a "default expires" that could be
overwritten later on with a new declaration but it seems that this is
currently not possible.
Cheers,
Samuli

Instructions for upgrading designer.war?
by Han Ming Low
Hi,
I understand that the designer.war is a project by intalio.
When looking at the source for the war at
http://anonsvn.jboss.org/repos/labs/labs/jbossrules/contrib/designer/desi...,
I saw the changes to be made to make it compatible with Drools.
I think I can do some of the steps like
1) changing the web.xml to use tomcat instead of jetty
2) added slf4j library
3) move lib/bpmn2 library to web-inf/lib
4) changes to oryx.js that involve
- commenting out the header
- commenting out the log
- change the repository url from "/designer/uuidRepository?uuid="+ uuid to

However, I'm not sure what is the BPMN2 import/export classes to replace in
WEB-INF/classes
Can someone could tell me which are the classes?
I can also help to update the designer. :)
Thanks.

How to write a rule that fires when it matches against specific facts in working memory.
by groovenarula
Hello,
I have a fact called 'Option' :
public class Option {
private String code;
private Item item;
public String getCode() {
return code;
}
public void setCode(String optionCode) {
this.code = optionCode;
}
At any point in time, the working memory can have several Option instances
with different code values. My rules need to fire specifically when the
working memory contains a specific set of options. e.g. Rule 1 should fire
if and only if the working memory contains 2 option instances one with code
"P1" and the other with "P2" (order should not matter).
I tried to use 'forall' as follows :
rule "Matched Options"
when
forall (
Option ( code == "P1" || code == "P2" )
)
then
//insert( new IsPriced( i ) );
System.out.println ( "Priced using G/S ");
end
However, the rule above never fires. Maybe I should be taking a different
approach. I'm still learning through how to create rules. So any
help/suggestions on how to tackle the above will be appreciated.
Thanks
Gurvinder
