Methods Summary
private booleancheckVSExists(java.lang.String vsID, com.sun.enterprise.config.serverbeans.Config config)
Checks whether a virtual server with given id is available in the given server. Current hierarchy is that the http-service has a single virtual-server-class and which has many virtual-servers. An Http lsnr can have any one of these virtual servers as its default-virtual-server.

param
vsID String representing the id of vs specified
param
server ConfigBean representing the server.xml
return
true if and only if the given vsID exists in given Server, false otherwise

        return getDefaultVirtualServer(vsID, config) != null;
private final com.sun.enterprise.config.serverbeans.VirtualServergetDefaultVirtualServer(java.lang.String vsID, com.sun.enterprise.config.serverbeans.Config config)
Get the default virtual server given an ID and the config in which teh server should be found.

param
vsId the id of the virtual server to be found
param
config the config to be searched for the virtual server
return
the virtual server object, if found; null otherwise.
