I have a project that uses BlazeDS as the data service deployed to a localhost WebLogic server. I have configured the Flex Server properties to point to the proper WebLogic server directory so I can run and debug the app from within Flash Builder. When I do this, however, I am unable to redeploy the application using ant tasks. The wldeploy task encounters an access denied error. As soon as I close Flash Builder and it finishes shutting down, I can deploy using the ant task. It seems that Flash Builder is creating some kind of resource lock on the Weblogic server directories, thus preventing the server from refreshing the files. This was not a problem with Flash builer 4.6. The configurations are the same.
UPDATE: I ended up switching to Eclipse Juno and using the Flash Builder Plugin. Everything seems to work fine with this configuration, however using Flash Builder proper with the same settings has the same "locking" issue.
