Packages and Multiple Jars

• One Application should not do all. Look for logical breaks.

• Breaking code down by packages per Application makes for;

  • Easier Testing/Debugging
  • Faster Redeployments

• 1 or 2 Packages per Jar makes for faster redeployments

  • Most appservers can recognize which EJB-Jars have been updated, and will only redeploy those
  • For Developers, most AppServers have unpacked directories that updated jars can be immediately redeployed to during a build.
