We have a ear with a ejb 3.0 and ejb2.x specificaiton. We are able to deploy the ear with only the ejb 3.0 without any errors. When the ear is deployed with the ejb 2.x a redeploy error is displayed and is not deployed properly. The error states that the server must be stopped or another program is using the file to be deleted. As this is not that a case due to the server be cycled before each deployment and the user has access to the file (read and write); is there a preferences setting that needs to be adjusted on ear before deployment when working with ejb 2.x?
