You may be stuck on the following issue
org.activiti.engine.ActivitiException: Could not find an implementation of the org.activiti.cdi.spi.ProcessEngineLookup service returning a non-null processEngine. Giving up. at org.activiti.cdi.impl.ActivitiExtension.lookupProcessEngine(ActivitiExtension.java:106) at org.activiti.cdi.impl.ActivitiExtension.afterDeploymentValidation(ActivitiExtension.java:68)And find many friends on the Internet with posts describing the same issue :

So we not just feeling alone; that is a good point ;)
Actually you may produce the Activiti Engine instance with a 'programatic' CDI OR a Spring activiti.cfg.xml.
This is the complete JBoss setup on BitBucket :
https://bitbucket.org/meyerd/activiti-cdi-jbossas7.1.1-setup
The activiti user guide doesn't not explain clearly the two possibilities. Here there are :
(1) Default CDI producer starts up with org.activiti.cdi.impl.LocalProcessEngineLookup
-> This is supposed to load the activiti.cfg.xml using Spring-context.
-> You need to add /META-INF/beans.xml as usual for CDI.
(2) You may overload that default CDI producer writing your own (so that you get a chance to quit Spring some day).
-> Provide a class that implements ProcessEngineLookup (see bitbucket resource).
-> Define classname in /META-INF/services/org.activiti.cdi.spi.ProcessEngineLookup
Checking with the bitbucket sample code, (2) is OK, so what is wrong with (1) ?
The cause is contained within the first lines of the complete stacktrace : a NoClassDefFoundError (!)
Caused by: java.lang.NoClassDefFoundError: org/springframework/core/env/EnvironmentCapable
So actually, this is just a springframework version mismatch (!) The user guides still asks for adding spring-context3.0.3.RELEASE.
BUT currently, Activiti 5.12.1 defines spring 3.1.2...
With the correct version, activiti-CDI is stating as a charm !
These are the dependencies I used :
... Shall this post save your time ;)
