Applications | Enterprise Applications | appname | Map virtual hosts for Web modules

Web modules can be installed on the same virtual host or dispersed among several virtual hosts.

This panel is the same as the Map virtual hosts for Web modules panel on the application installation and update wizards.

On this panel, each Web module must map to a previously defined virtual host, identified under Virtual host. We can see information on previously defined virtual hosts by clicking...

...in the administrative console.

Virtual hosts enable you to associate a unique port with a module or application. The aliases of a virtual host identify the port numbers defined for that virtual host. A port number specified in a virtual host alias is used in the URL that is used to access artifacts such as servlets and JSP files in a Web module. For example, the alias myhost:8080 is the host_name:port_number portion of the URL...

http://myhost:8080/servlet/snoop

The default virtual host setting usually is default_host, which provides several port numbers through its aliases:

80

An internal, insecure port used when no port number is specified

9080

An internal port

9443

An external, secure port

Unless you want to isolate your Web module from other modules or resources on the same node (physical machine), default_host is a suitable virtual host for your Web module.

In addition to default_host, WAS provides admin_host, which is the virtual host for the administrative console system application. admin_host is on port 9060. Its secure port is 9043.

To change a mapping:

1. In the list of mappings, select the Select check box beside each Web module that you want mapped to a particular virtual host.

2. From the Virtual host drop-down list, select the desired virtual host. If you selected more than one virtual host in step 1:

   1. Expand Apply Multiple Mappings.

   2. Select the desired virtual host from the Virtual Host drop-down list.

   3. Click Apply.

3. Click OK.

Web module

Name of a Web module in the installed (or deployed) application that you selected on the Enterprise Applications page.

Virtual host

Name of the virtual host to which the Web module currently is mapped.

Expanding the drop-down list displays a list of previously defined virtual hosts. To change a mapping, select a different virtual host from the list.
