A deployment descriptor is an XML file that describes how a module
or application should be deployed, by specifying configuration and
container options. web.xml is a deployment descriptor file for Web
applications. WebFacing applications use web.xml to store information
such as the properties you set for your project; for example, the
properties you choose for handling user IDs and passwords are stored
in web.xml.
WebFacing applications can be deployed to the WebSphere® Application Server or the
IBM® i integrated
Web application server.
- Use the Websphere Application Server Network Deployment (ND) if
you are deploying WebFacing applications requiring support for high
availability and failover.
- Use the Websphere Application Server Express or Base if you are deploying WebFacing/HATS linked
applications or WebFacing applications that use the application bridge.
This configuration does not support high availability and failover.
- Use the IBM i integrated
Web application server if you are deploying WebFacing applications
and have limited IBM i system resources that cannot optimally
run the WebSphere Application
Server. This configuration does not support high availability and
failover.
