Use the deploytool utility to deploy and package your J2EE applications and components, create and edit J2EE deployment descriptors, and create and edit J2EE Application Server specific deployment descriptors. If the application is not J2EE compliant, an error message is displayed.
Only one session of the deploytool utility can run with a specific user directory. A lock file is created to ensure that only one utility session is running. A message is displayed if a lock file is detected.
