An archive is produced after a developer creates a package profile and executes a build on a package. This archive can only be created in the Eclipse edition of Unwired WorkSpace.
In Unwired WorkSpace, a developer executes a build process so that it creates a .jar archive file, which contains both a deployment unit and a corresponding descriptor file. A deployment archive can be delivered to an administrator for deployment to a production version of the Unwired Server.
In general, using an archived file is more efficient when deploying applications to managed servers. However, archiving files makes updating the application more difficult, as it requires a redeployment of the entire archive file.
