Subject Re: Watchdog ONLY testing unpacked WAR behaviour ???
Date Tue, 21 May 2002 02:35:22 GMT
OK - before anyone wastes any time on this...

I've got down the source and had a look at it - It DOES take into 
account the fact that I may be running from a jar.

At the moment it looks like the webcontainer must be returning the 
String "null" for getRealPath() - hence my confusion over the watchdog 
error message.

I'm off to confirm this - if it is the case I will not clutter up your 
list with any more mails.

Cheers,



Jules
