After installing the Enterprise Server and starting a domain, you can deploy (install) Java EE modules. During deployment and as the application is changed, a module can go through the following stages:
Before deploying a module, start the domain.
Because modules are packaged in archive files, specify the archive file name during deployment.
Enabling or Disabling
By default, a deployed module is enabled, which means that it is runnable. To prevent access, disable the application or module. A disabled module is not uninstalled from the domain and can be easily enabled after deployment. For more information, see Disabling a Deployed Application or Module.
To replace a deployed module, redeploy it. Redeploying automatically undeploys the previously deployed module and replaces it with the new one.
To uninstall a module, undeploy it.
