EAR Files

• Most AppServers unpack before deploying contents

• Many Appservers will check to see which jars (especially ejb jars) have been changed before redeploying jar (ex. Orion, JBoss)

• Deploying Jars in an Ear helps EJB Container keep classes synchronized across jars.

• If large file being copied over network, copy to another extension, then rename

  • many deployment scanners get confused with half-copied files, crashing the AppServer and forcing a restart
