[Urgent] Error in ontext assist in DSLR Editor
by hamza bakkali
Hi All,
I have been using drools 4 for couple of months now and I am starting to get
the hang of it. We recently decided to move to Dools 5 with Eclipse 3.4.2
(Ganymede).
We unfortunately hit a major 'show stopper' (for us). In the DSLR editor:
Context Assist + space + enter removes/replaces the whole line, not only the
place holder.
In other words:
DSL:
[*][]Log : {msg}=System.out.println("{msg}");
[*][]id1="some id label"
DSLR:
rule "MyRule"
when
then
end
If I Press L , control space --> the line Log:{msg} appears in the context
menu. Hit enter I get
Log :{msg}
Now, If want to replace msg by id1. I position the cursor in the {msg}, hit
ctrl space, id1 shows in the list. I hit enter the whole line disappear, and
I am left with
id1
instead of
Log : id1
Is this a setting somewhere in eclipse itself?? I doubt it.
The same thing use to work as expected in Drools 4.
thanks.

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

Unable to start drools-server 5.1.1 or 5.2.0.M1 under Tomcat 6.0.30
by A R
Hi,
I don't seem to be able to get the drools server (5.1.1 or 5.2.0.M1) to
startup correctly under Tomcat 6.0.30.
Here are the steps I've taken:
1) cp drools-5.1.1-server.war to my webapps directory
2) deleted servlet-api-2.3.jar due to a conflict with tomcat's
servrlet-api.jar
3) On startup however I get the following error in the logs (same error for
5.2.0.M1):
org.springframework.beans.factory.parsing.BeanDefinitionParsingException:
Configuration problem: Failed to import bean definitions from URL location
[classpath:knowledge-services.xml]
Offending resource: class path resource [beans.xml]; nested exception is
org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line
25 in XML document from class path resource [knowledge-services.xml] is
invalid; nested exception is org.xml.sax.SAXParseException:
cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration
can be found for element 'drools:execution-node'.
Where line 25 in the knowledge-services.xml file is:
<drools:execution-node id="node1" />
Full stack trace is here:

Any help appreciated.

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.....

Drools and JBoss Seam proxies
by sherlock
Hi,
a newbie question.
I am asserting references to JBoss Seam beans (SFSB) as Drools facts and
it looks that the rule engine does not recognize them as instances of
the original bean POJO class - it looks that it sees the JBoss Seam proxies.
When I use an intermediate non-Seam enabled wrapper POJO class which
wraps the Seam bean everything works, but now there will be an
additional need to maintain set of wrapper classes and in addition DRL
conditions code is cluttered with statements to access the JBoss Seam
beans...
Surely I am missing something, but I cannot find out so far. Googling
didn't seem to find anything helpful.
The environment is: Seam 2.2.0.GA, Drools 5.1.1
Thank you in advance!

Drools.NET active?
by Sean Su
Does anyone know if Drools.NET is something Drools team in JBoss works on?
Or it is maintained by other team which just named the product Drools.NET.
The website and document seem to me that the project is not active. Does
anyone know?
Thanks
