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.
