When you redeploy a web service application, the running application is automatically stopped and then restarted.
Redeploy an application if:
You have made changes to the application and you want to make the changes available.
You have made changes to the deployment plan.
You want to redeploy an entirely new archive file in a new location.
When you redeploy an application, you can redeploy the original archive file or exploded directory, or you can specify a new archive file in place of the original one. You can also change the deployment plan that is associated with the application.
Note:
Applications that were previously deployed without a version cannot be redeployed. To redeploy the not-versioned applications, you need to undeploy and deploy the application.
The steps that you follow to redeploy a web service application are identical to those required when you first deployed the application, as described in "Deploying Web Service Applications", with two exceptions: you must redeploy the application with a new version, and you can optionally set the retirement policy for the current version. Both of these actions occur at Step 3 of redeployment process, as shown in Figure 3-6.
