Hello,
I am currently working on a Drools project using eclipse kepler and the
drools plug-in from drools 601.
I have a main java class that contains POJO classes representing facts and
the initialization of the kie container and session. When executing the
command System.out.println(kContainer.verify().getMessages().toString()); I
get the following messages:(note the warning No files found for KieBase
InfectionRules, searching folder
)

The kie initialization module has the following code:

final Patient p1 = new Patient( "MrJones", 45, 1,
false,false,true,37.0,

kSession.insert( p1 );
// get a reference to the entry point and insert events
EntryPoint nursingStream = kSession.getEntryPoint(
"NursingStream" );
final CPIScore cpiScore1 = new CPIScore( p1,"initial",7);
nursingStream.insert( cpiScore1 );
clock.advanceTime( 75, TimeUnit.HOURS );
final CPIScore cpiScore2 = new CPIScore( p1,"3days",7 );
nursingStream.insert( cpiScore2 );
I am running this class directly from the Eclipse Run menu option. I have
installed maven but Im not using it (yet)
The kmodule.xml file has the following format:
<?xml version="1.0" encoding="UTF-8"?>
<kmodule xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://jboss.org/kie/6.0.0/kmodule">
<kbase name="InfectionRules" eventProcessingMode="stream"
packages="InfectionRules">
<ksession name="VAPSession" type="stateful"
clockType="pseudo" />
</kbase>
</kmodule>
(I have tried to change the packages field of kmodule to *, but it does not
work either.)
And the directory structure where both the java and drl code reside is:
C:\TFM\Infections\Workspace\InfectionRules\VAP\src\main
Subdirectory java contains the java classes and resources the drl file.
The target directory is located under ..\VAP\target\ with the following
structure:
From Eclipse IDE this is the project structure
Any idea as to what Im doing wrong? I don´t know why the kmodule does not
locate the kbase in the directory
\TFM\Infections\Workspace\InfectionRules\VAP\target as this directory
contains the drl file vap.drl in the rules subdirectory. Although I get
later a null pointer exception, I guess that it has to do with this warning,
as if there is no kbase located no session can be used.
Thanks in advance!
Best regards
Natalia
