After installing the Application Server and starting a domain, you can deploy (install) J2EE applications and modules. During deployment and as the application is changed, an application or module can go through the following stages:
Before deploying an application or module, start the domain.
Deploy (install) an application or module. Because applications and modules are packaged in archive files, specify the archive file name during deployment.
Deployment is dynamic: you don’t need to restart the server instance after you deploy an application or module for applications to be available. If you do restart, all deployed applications and modules are still deployed and available.
By default, a deployed application or module is enabled, which means that it is runnable and can be accessed by clients. To prevent access, disable the application or module. A disabled application or module is not uninstalled from the domain and can be easily enabled after deployment.
To replace a deployed application or module, redeploy it. Redeploying automatically undeploys the previously deployed application or module and replaces it with the new one.
To uninstall an application or module, undeploy it.
