[rules-users] No setter found for property 'kBaseName' in class 'org.kie.spring.factorybeans.KBaseFactoryBean'

[profversaggi]

Hi Vinodkiran!

What I did was this - I embarked on a *pure* process and then merged the
results. My goal was to create a *pure* Maven project without any specific
natures of any kind imposed upon them (in Eclipse) which would run a Drools
KIE function as well as a Spring MVC WEB App function from that single
Maven project.

Prework: (A) I created a standard Drools test project using a Eclipse
Drools KIE *Nature* and got it running. (B) I created a standard Spring MVC
WEB project using the Eclipse Spring 3 *Nature* and got that running
properly as well. These would be inspiration for their pure Maven
equivalents counterparts.

First: I created a pure Maven Drools KIE project and got that running with
the standard DroolsTest and corresponding Sample.drl running as expected.
So to be clear it was a Maven project that just so happened to run Drools
KIE in it. Execution took place in Eclipse

Second: I created a totally different pure Maven Spring MVC WEB project and
got that running locally using Tomcat7. Again - it was a pure Maven project
that just so happened to run a Spring 3.2.3 MVC Web App in it and deploying
it as a WAR to a local Tomcat7 installation. Execution took place through a
web browser: http://localhost:8080/maven-spring

Third: I created another totally different pure Maven project which was a
combination of the (1) pure Maven Drools KIE project and the (2) pure Maven
Spring MVC WEB project. I copied the appropriate directory structures over
from the individual projects to their respective places in the combination
project and (after a bit of fiddling) was able to run *each* (Drools and
Spring) projects functionality independently - directly from the single
(combination) Maven project. Execution for the spring portion initiated
through a web browser: http://localhost:8080/maven-spring-drools, and for
the Drools portion from the IDE.

Forth: Integration - this is where I started having the problems we are
corresponding about. The Drools doc tells us to use variants of the below
code to tie Drools KIE and Spring together - except it *never* tells us
where to put it.

<kie:kmodule id="sample_module">
   <kie:kbase name="kbase1" packages="org.drools.spring.sample">
   </kie:kbase>
</kie:kmodule>

<bean id="kiePostProcessor"
class="org.kie.spring.KModuleBeanFactoryPostProcessor"/>


I found references to putting it in the Spring application-config.xml file
so I tried it there. Then I received the following error:

ERROR:
No setter found for property 'kBaseName' in class
'org.kie.spring.factorybeans.KBaseFactoryBean'
[config set: maven-spring-drools/web-context application-config.xml
/maven-spring-drools/src/main/resources/spring line 8 Spring Beans Problem

That's when Mark suspected the current code looks for the different xml,
depending on the container. i.e. spring looks for kmodule-spring.xml.
Perhaps what is needed is to fallback to kmodule.xml if that is not
present. (I haven't tested that yet).


In any case I tried another avenue toward integration and that is
programmatically integrate Drools KIE into the Spring MVC Web App
Controllers - which as it turned out  (after a bit of tweeking) - it work
quite well.

I'm still very curious as to how to accomplish the integration the way the
documentation articulates, but I quite glad it can be done programmatically
as well.

If I can help out in any way just ask ....
