Question about renaming myapp.war to ROOT.war

[Ken Bowen <kb...@als.com>]

Hi All,

Renaming myapp.war to ROOT.war (as recommended) in order to make myapp 
the default application has worked fine.
However, I've seen one bit of odd behavior as follows.  If request is 
the incoming HttpServletRequest, then:

--  when the app is running from webapps/myapp,  one gets 
request.getContextPath() = "/myapp"

--  when the app is running from webapps/ROOT,  the value of 
request.getContextPath() is the empty string.

It's almost as if the value of request.getContextPath() is the value of 
the Context 'path' attribute when the Context was stored under Host in 
the old way.

Is this essentially correct, or am I missing something here?

Thanks in advance,

Ken Bowen

This is expected behavior.

Yep, pretty much.

The idea is that you can do something like:

request.getContextPath() + "/bar/baz" and always get an absolute URI. If
your context name is "foo", then you get "/foo/bar/baz". If you are
running the root web app, you get "/bar/baz", which is expected (rather
than, say, "//bar/baz").
