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 i5/OS
® 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 ND 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 i5/OS integrated
Web application server if you are deploying WebFacing applications and have
limited i5/OS system
resources that cannot optimally run the WebSphere Application Server. This
configuration does not support high availability and failover.
