Deployment warning: Exception while downloading files of application
I am deploying my application (sap.com/JSF_Task_EAR) with ejb module for the first time, result - successful.
Then i am trying undeploy my application, undeploy view in Developer Studio return successfully result, but actually directory "sap.com/JSF_Task_EAR/" was not deleted, because file "sap.com\JSF_Task_EAR\orpersistence\jars\JSF_Task_EJB.jar" locked for some reason.
If i am trying deploy this application for the second time, i am getting the next warning:
[ERROR CODE DPL.DS.5082] Exception while downloading files of application sap.com/JSF_Task_EAR4.
How i can redeploy my application without restarting server?
Why JSF_Task_EJB.jar can be locked?
