I assume you replaced both drools-core and drools-compiler with those for 5.3?

Furthermore, you should endeavour to use knowledge-api which contains the "public" API.

Can you isolate the rules from grail, to understand if it is an integration issue too?

Hi,

I was using drools 5.2.0 in my grails 2.0.0.M2 application. I use Drools
expert to execute a .drl file I have. The three dependencies that I have set
up for this to work was:

       runtime 'org.drools:drools-core:5.2.0.Final'
       runtime 'org.drools:drools-compiler:5.2.0.Final'
       runtime 'com.sun.xml.bind:jaxb-xjc:2.2.4'

However when I switched to drools 5.3.0. The rules are not getting executed
or there are some problems. There is no stacktrace or log. I have no idea
what is going on. My guess is that some of the dependency jars or classes
are missing. Any insight into this?

Thanks,
Abdul
