Here are the steps how to create a name based virtual host
in weblogic server 10 and how to deploy a web application in
the virtual host using weblogic console.

You must be aware that a network channel is like a network
connection in weblogic. A network channel is a unique

Listen address = 127.0.0.1, Listen Port = 7003,
>
Leave External Listen address and Leave External Listen Port
blank
>
-> Click on 'Finish'
>
-> Save changes
>
-> Activate changes

>

>
-> Activate changes
>
Note: After this step a virtual host is created. It does not
mean anything unless you configure the virtual host as shown

Step 3: Configure virtual host
>
Go to console -> left pane -> wl_server -> environement ->
virtual hosts
>
-> Click lock & edit
>
Right pane:
>
-> Click on 'myvh' virtual host link in the 'Virtual Hosts'
table.

box.

Step 4. Deploy application to virtual host

Go to Console -> left pane -> wl_server -> deployments
>
-> Click lock & edit
>
Right pane:
>
-> Click on 'Install'
>
-> Click on "upload your files" link
>
-> Click "browse" (against 'deployment archive' )

button
>
-> Click on "deployment targets" tab

Step 5. Create DNS entry in your hosts file.
>
For linux hosts file is: /etc/hosts Append the following
line to the file as super user.
>
127.0.0.1 myvh.oracle.com
>
Save the changes to 'hosts' file.
>
>
Note: Just saving the changes to 'hosts' file is enough to
activate the DNS entry.
>
>
Step 6. Start the application.
>
Go to Console -> left pane -> wl_server -> deployments ->
>
Right pane:
>
-> Select 'sample.war'.
>
-> click on 'Start'.
>
-> Complete the start process.
>
>
Step 7. Access the virtual hosted application.
>
Now you should be able to access the following url only from
the machine where you modified the 'hosts' file as mentioned
above. http://myvh.oracle.com:7003/sample/
If you want to use access the above url from any machine,
appropriate DNS entries need to be created by your network
administrator in your network Router.
