  == Preface ==
  This section of the FAQ discusses common questions related to web application 
deployment.
  == Questions ==
+  1. [#Q1 Why does tomcat 5 create context configuration files?]
+  1. [#Q2 Why does the memory usage increase when I redeploy a web 
application?]
+ 
+ == Answers ==
- '''Why does tomcat 5 create context configuration files?'''
+ [[Anchor(Q1)]]'''Why does tomcat 5 create context configuration files?'''
  
  Unlike tomcat 4.x, tomcat 5.x creates context configuration files for you in 
its conf/[Engine name]/[Host name] directory. This is part of the change in 
tomcat's configuration mechanism from version 4.x to make overall configuration 
more robust, flexible, and enterprise-friendly. Note, however, that this has 
changed the recommended deployment practices for web applications. These 
context configuration files are created by tomcat, but not removed by tomcat, 
because the user may have changed them or other files in the conf directory. 
The suggested practice for tomcat 5 is to place context configuration files in 
the META-INF/context.xml directory of your webapp, and use Tomcat's Manager 
webapp to deploy/undeploy your applications. More details can be found here:

+ [[Anchor(Q2)]]'''Why does the memory usage increase when I redeploy a web 
application?'''
  
  Because the Classloader (and the Class objects it loaded) cannot be recycled. 
They are stored in the permanent heap generation by the JVM, and when you 
redepoy a new class loader is created, which loads another copy of all these 
classes. This can cause {{{OufOfMemoryErrors}}} eventually.
