Placing more than one Struts2 application in the same container causes a
failure to start when one or more contains Xalan 2 JAR
-------------------------------------------------------------------------------------------------------------------------------
Key: WW-3249
URL: https://issues.apache.org/struts/browse/WW-3249
Project: Struts 2
Issue Type: Bug
Affects Versions: 2.1.6
Environment: Same problem applies across both Windows and Linux on
Intel hardware
Reporter: Joe Hoy
Priority: Critical
If I try to place two applications using Struts2 in the same container, I get
this. I'm using Guice as the DI engine:

Obviously this is a pretty serious issue - I can't find it anywhere in here.
Of course, I could be doing something stupid, so if that's the case please let
me know!
Thanks a million,
