Hello, In Drools 6.0 the "deployment unit" is a JAR. It is built when you "Build and Deploy" the project (from the Project Editor). Drools Workbench deploys the JAR to the workbench's Maven repository; that can be added to your projects pom.xml as an additional repository and the JAR added as a dependency. The Repository URL will be of the format: http://<hostname>:<port>/<webcontext>/maven2/ where <hostname>, <port> and <webcontext> reflect your deployment configuration. There have been other emails to this mailing list asking similar questions over the last couple of days. Please read those too, as they embellish on this answer. With kind regards, Mike On 29 November 2013 09:46, nelson.wan <nelson.wan(a)hotmail.com&gt; wrote:
