[opencms-dev] using jstl import from another context to access OC pages

[Stephan Hartmann]

Hi Rob,

the problem is that opencms extracts the path of the requested resource from 
the requests path info (HttpServletRequest.getPathInfo()). This is normally 
the path portion behind /opencms/opencms.
But for an including request (and this is what is done behind the scenes of 
the import tag) this method returns the path info of the original request and 
not the one of the included resource (opencms servlet). If your including 
page is a jsp this might alway be null.
The servlet container instead puts the path info of the included resource into 
a request attribute "javax.servlet.include.path_info".
Now the bad news is that there is no way around the problem without patching 
opencms.

The reason why it works for an absolute URL is that this is not done by an 
include but with an URLConnection.

Forwarding should also work (therefor you need to get hold of opencms' 
ServletContext and then fetch a request dispatcher for the opencms resource).

Regards,
Stephan
