Subject [jira] Created: (BEEHIVE-960) Reload war problem when following tutorial
Date Mon, 03 Oct 2005 14:23:47 GMT
Reload war problem when following tutorial
------------------------------------------

         Key: BEEHIVE-960
         URL: http://issues.apache.org/jira/browse/BEEHIVE-960
     Project: Beehive
        Type: Bug
  Components: Tutorials  
    Versions: V1Beta    
 Environment: Not Applicable
    Reporter: Thomas Preston
    Priority: Minor


In the final step of create controls tutorial having done all other steps successfully, have
a problem with redeployment of the war:

http://beehive.apache.org/docs/1.0m1/controls/tutorial_controls.html#test_3

Looks like redeploy needs to undeploy and then you have some object of type shared.SharedFlow
in the session. When the redeploy occurs the shared.SharedFlow class can't be found at the
time that it needs to reload the session.  This is no big deal as you can stop and start the
server to see the new code working, but it makes the demo not very nice.  Here is the stack:
