1. Go to Application Server Control for your Middle-Tier
  2. In the System Components section, click on "home"
  3. Select Applications
  4. Select the Application (e.g. mfjp) application and click Redeploy
  5. In the J2EE Application field, browse to the EAR file, e.g. d:\data\java\myWork\mfjp\deploy\mfjp.ear
  6. Click Redeploy
  7. Click OK

    Note: An alternative to using Application Server Control (in case your laptop is getting low on memory) is to use the dcmctl command line utility, e.g.: 

    cd /d d:\ora101202mt\dcm\bin
call dcmctl redeployApplication -f d:\data\java\myWork\mfjp\deploy\mfjp.ear -a mfjp
