ERROR DESCRIPTION:                                              
This APAR provides the option to disable the                    
setting fileServingEnabled at the webcontainer level. This      
setting will                                                    
override fileServingEnabled="true".                             

LOCAL FIX:                                                      

PROBLEM SUMMARY

USERS AFFECTED:
 IBM WebSphere Application Server file
serving
users.

PROBLEM DESCRIPTION:
There is no way to override all

applications on a given applicat
ion                             server
to prevent them from serving
static files regardle
ss of their
individual deployment settings.


RECOMMENDATION:
None



The WebContainer allows for fileServingEnabled to be set on a
global level across a given application server. But, that custom
property is overridden by the specific deployment information of
each application. Thus, the current property only applies as a
backup in case an application does not define the
fileServingEnabled setting itself. There is no way to globally
override this setting on a given application server.

PROBLEM CONCLUSION:                                             
A new WebContainer custom property has been added that disallows
file serving on all applications (except the administration     
console) on a given application server. Set the new WebContainer
custom property                                                 
com.ibm.ws.webcontainer.disallowAllFileServing to true to       
disable all file serving on a given application server. This    
custom property is not case sensitive.                          
Please refer to the following technote for instructions on      
enabling WebContainer custom properties:

http://www-1.ibm.com/support/docview.wss?rs=180&uid=swg21205400

1) Copy PKxxxxx.pak file directly to the maintenance directory

2) Shutdown WebSphere
Manually execute setupCmdLine.bat in Windows or . ./setupCmdLine.sh in Unix from the WebSphere instance that maintenance is being applied to.
