      hi,

       

      I use bpmn2 eclipse plugin create a process flow and program a test.

       

      I get below output messages:

      (null: 2, 307): cvc-elt.1: Cannot find the declaration of element 'bpmn2:definitions'.

      (null: 33, 63): cvc-elt.4.2: Cannot resolve 'dc:Point' to a type definition for element 'di:waypoint'.

      (null: 34, 63): cvc-elt.4.2: Cannot resolve 'dc:Point' to a type definition for element 'di:waypoint'.

      (null: 37, 63): cvc-elt.4.2: Cannot resolve 'dc:Point' to a type definition for element 'di:waypoint'.

      (null: 38, 63): cvc-elt.4.2: Cannot resolve 'dc:Point' to a type definition for element 'di:waypoint'.

      hello world

       

      Could anybody tell me how to resolve above NullPointerException. I don't find any solution from google's results.

       

      and where I can find an full guider of how to use the BPMN2 eclipse plugin, thanks.

       

      Forgive me for my bad english.Thanks very much.
