Unfortunately, it will not work in earlier versions :-( .

Other JBT project may not have the same issue because those project are 
based on Dynamic Web Project,
 so the sort of creating a Virtualcomponent work is done by Dynamic Web 
project,  WTP changes all their
 creating Virtualcomponent way by using the new method in WTP 3.03 when 
creating a new Web project or J2ee project.

The issue is:  in early WTP versions,  it should use the following way 
to create the VirtualComponent:
final IVirtualComponent c = ComponentCore.createComponent(project);

and in WTP 3.03, we have to do it by:  final IVirtualComponent c = 
ComponentCore.createComponent(project, false);
the *false* parameter is a flag that whether to check a configure file 
exist or not, in our scenario , it should not check.
and the *ComponentCore.createComponent(project, false) * method is not 
exist in early versions.
for now, the ComponentCore.createComponent(project) works as  
ComponentCore.createComponent(project, true),
if it can be changed to work as ComponentCore.createComponent(project, 
false), it will works and it's reasonable ,
I will raise a bug to wtp, if they can change their implementation, that 
would be good, if they wouldn't change, we have to try
to check if the componentCore has the method using refect way.
