anyone? please reply someone !
Just so you wont feel like screaming in the desert:
1) first of all RTFM ;-)
an answer could be:
a WAR file is deployed in the web-container (tomcat).
No entity-container(jboss) means no EJB's. Thus the seam classes are 'just' POJO's and not entity beans / session beans etc.
2) integrating jBPM into a project
This is documented by a some blogs and here on site. Have a look around. If it didn't work out or you find a better way: please post and we all learn.
