tRules throwing exception and cannot find DRL file.

[balatrash]

Hello,

I implemented an embedded rule in my metedata in Talend v6.3.1. In my studio, the job runs perfectly fine. But when I build or publish job to TAC I am getting the below error stack trace:

I copied this path: 'rules/final/version_age_fact_0_1/Rule10.1.drl'  to the root folder where the .bat file is and the job worked perfectly on my local machine. So in reality Talend doesn't know that he has to go to 'src/main/resources/rules/final/version_age_fact_0_1/Rule10.1.drl'. 

Is there a way to force to the Rule file ClassPath or set it in the project settings of the Studio? This is a very interesting topic for me and team as we attempting to implement a Business Rule DQ gate using Drools.

Thank you,

Bahaa

With your subscription solution, could you please create a support case on talend support portal? Our colleagues from support team will check your issue to see if a patch will be needed.
