I want to integrate drools rules with activiti and on deploying my .BAR file (which contains .drl file also) I get an error message Deployment xxxx does not contain rules.
I am new to java, activiti and drools.

I have followed the steps on the thread http://forums.activiti.org/content/businessruletask-deploy-error.
therefor I have added these jars to /path/to/webapps/activiti-explorer/WEB-INF/libs/ as well as to the maven dependencies in my project:
drools-api-5.1.1.jar
droools-core-5.1.1.jar
drools-compiler-5.1.1.jar
mvel2-2.1.0.drools.jar


Also I have edited the applicationContext.xml file  in /path/to/webapps/activiti-explorer/

I have created a simple project using eclipse with a bpmn file and a business rule.
After deploying when I start the process and the user fills the form an error occurs- Deployment xxxx does not contain rules.
The user at the thread I have mentioned above suggested to read chapter 12 of the book- activiti in action, but I could not understand much of it. For eg in which directory should I include the java code, mentioned in the book, with my project.
Any help would be highly appreciated.

It's very hard to see with this info what went wrong. You need to have the .drl in the .bar. You need to deploy the bar to the engine. You need to reference the correct rule in your process … did you do all that?

By the way, the code of the book is freely available at http://www.bpmnwithactiviti.org/book_sourcecode.html
