Follow that structure

Hello,
I had already tried something like that by changing the packages field
in the kmodule file into *packages=”rules”* as this is the directory
where the VAP.drl file resides. But I still get a *null pointer exception*when executing
the *container
verify*, although I do not see a warning anymore:
The error comes from the line 36 (container verify):
System.*out*.println(kContainer.verify().getMessages().toString());
I am running out of ideas, I also thought that it maybe has something to
do with maven as I have read that drools 601 expects a maven structure, so
I definitely needs a pom.properties. I have a pom.properties but is has no
content, only this:
version=${project.version}
groupId=${project.groupId}
artifactId=${project.artifactId}
Thanks!

Try creating a directory called: *InfectionRules inside the
src/main/resources/*
*and then put the rules inside there.*

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…”)

I am running this class directly from the Eclipse Run menu option. I have
installed maven but I’m 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
<
http://www.w3.org/2001/XMLSchema-instance>"*
xmlns=*"http://jboss.org/kie/6.0.0/kmodule
<
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 I’m 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
