You must be aware that a network channel is like a network
connection in weblogic. A network channel is a unique
combination of listen address, listen port, and protocol.
In order to create a virtual host you first need to created
a network channel.
Go to console -> left pane -> wl_server -> Environemnt -
>servers
-> Click Local & Edit
Right pane:
-> Go to 'exampleServer' -> protocols -> channels
-> Click on Lock & Edit
-> Click New
-> Enter following details for channel.
Name="mychannel", protocol=http
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
Note: After this step you have created a network channel.
That means your server
will listen at given listening address and port. Try
accessing http://127.0.0.1:7003
Step 2. Create new virtual host
Go to console -> left pane -> wl_server -> environement ->
virtual hosts
-> Click lock & edit
Right pane :
-> Click on New
-> Enter Name 'myvh'
-> save 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 in the next step.
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.
-> Enter 'myvh.oracle.com' in the 'Virtual Host Names' text
box.
-> Enter 'mychannel' in the 'Network Access Point Name'
text box.
-> Save changes.
-> Click on 'Targets' tab.
-> Select 'exampleServer' in the 'servers' section.
-> Save changes.
-> Activate changes
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' )
-> select "sample.war"
-> Click "Next"
-> Choose 'sample.war' in the "location" section
-> Choose "Install this deployment as an application" radio
button
-> Click on "deployment targets" tab
-> select 'myvh' -> Next -> Next -> Finish
-> Save changes
-> Activate changes
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
