[rules-users] using Drools in Tomcat 6.0 enviourment

[Erez Zarini]

Hi,

I am new to Drools. 

I have successfully created a project from the Examples provided at the site
using Java APP project.

but when trying to move it as a Dynamic Web Project in Eclipse I get the
following Exception:

(the files kmodule and pom.xml resides in all subfolders of the project)

when running as a Java project (not Java EE) it seems to work find and
continues to find pom.xml instead of pom.properties.  

any ideas?
