I'm using an ant deployed dvdstore example from Seam 2.0.1.GA.
After I:
ordermanagement3, logout
I get an exception:
javax.servlet.ServletException: java.lang.IllegalArgumentException: no file extension in servlet path: /confirm
Console:
ERROR [ExceptionFilter] exception root cause org.jbpm.graph.def.DelegationException: javax.ejb.EJBTransactionRolledbackException: process business key may not be null ... ERROR [[default]] Servlet.service() for servlet default threw exception java.lang.IllegalArgumentException: no file extension in servlet path: /confirm ...
The problem was solved in Seam 2.0.2.GA (JBSEAM-2950) and it had nothing to do with with ordermanagement3 ;)
