John Augusto Charnet [http://community.jboss.org/people/jcharnet] created the discussion "jBPM5.1 with Spring + JSF + JPA environment Nullpointer" To view the discussion, visit: http://community.jboss.org/message/617043#617043 -------------------------------------------------------------- Hello, I'm using jbpm 5.1 as my workflow. I've done some tests, and in my junit tests everything worked so far. Now I'm trying to test in my web application, that uses JSF + Spring + JPA (hibrnate implementation). When I run my application, i'm getting the following exception: 10:41:10,740 ERROR SeamPhaseListener:128 - swallowing exception java.lang.NullPointerException     at
