I am getting following exception when trying to launch a store using Websphere commerce
A WebGroup/Virtual Host to handle / has not been defined
SRVE0255E: A WebGroup/Virtual Host to handle localhost:80 has not been defined.
I have tried this,

and this
http://pic.dhe.ibm.com/infocenter/iicdoc/v1r5m0/index.jsp?topic=%2Fcom.ibm.iic.doc%2Fts_installwgvh.html
but no use still getting error and unable to launch store(tried to launch store via Accelerator too).
What should I do to make it work properly?
回答1:
Looks like you are accessing your store either via http server or you have changed default web container port. Go to admin console Environment > Virtual hosts > defautl_host (or host that is mapped to your module if different) > Host aliases. Add new alias *:80. Restart the server.

Try the following:
-Access the WebSphere Application Server Administrative Console
-go to Applications -> Applications Types -> Websphere Enterprise Applications
-choose WC module from main screen
-then go to Virtual Hosts
-most cases the "WC_default_host" will be defined for all sub modules, make sure of that, if that is the case and still is not working, try to choose "default_host" for all sub modules and then save changes and restart.
I faced that problem once, and this way I have fixed it in my case.

I resolved a similar issue by temporarily disabling my Antivirus. So you may also want to check your antivirus settings and if possible temporarily disable it.

...or you may not have the webapp deployed at all. It is a quite common error message that I encounter when I try to access a Rest Api on the App while I have it undeployed! Please make sure you get it up before you try again.

If you having the message "WebGroup/Virtual Host to handle /yourwebmodule has not been defined" for some reason in your app Virtual host has not been defined
You can access the WebSphere Application Server Administrative Console
1ST Select : View -> All tasks
GOTO Applications -> Applications Types -> WebSphere enterprise applications
THEN click on application that having the problem and go to -> Virtual Hosts
Now you can see your Web module and a drop down in "Virtual host"
Select your Virtual host and save
A work around is to:
GOTO Environment -> Virtual hosts -> default_host
and use for Host Name (*) in the port that you are using and save, check if the option saved.
If for any reason you can't save, a web server is off line and can't synchronize settings.
