  Most locking issues will occur with JARs from /WEB-INF/lib, and are useally 
caused by access through URLs. Tomcat has mechanisms to allow avoiding locking. 
In Tomcat 5.0, a mechanism exists to prevent locking when accessing resources 
using the getResource method of the URL classloader (many applications, such as 
Xerces, do not set the use of caching to false before opening the URL 
connection, causing locking). If such a call occurs, resources inside the JARs 
will be extracted to the work directory of the web application. In Tomcat 5.5, 
this mechanism is disabled by default (as it has a non negligible influence on 
startup times, and is often useless), and can be enabled using the 
antiJARLocking attribute of the Context element. There is another lock 
prevention mechanism in Tomcat 5.5 (antiResourceLocking attribute), which will 
cause the web application files to be copied to the temp folder and run from 
this location. This has a larger impact on web application startup times,
  but obviously prevents locking on all resources of the web application. This 
also allows more flexible management operations as none of the web application 
resources will be locked, even while the web application is running (as a 
special note, when making changes JSPs without reloading the application, the 
changes has to be duplicated to the path where the web application resources 
have been copied in the temp folder). 
  
+ [[Anchor(Q6)]]'''Can I use UNC paths?'''
+ 
+ Yes. Make sure that the user that Tomcat is running as is able to access the 
path. This is particularly important when running Tomcat as a service since the 
local service account will '''not''' have the necessary permissions.
+ 
+ [[Anchor(Q7)]]'''Why can't Tomcat see my mapped drive when running as a 
service?'''
+ 
+ The mapped drives are part of a user's profile and they are not used when 
running as a service. You should be OK with UNC paths.
