Modified: src/java/org/apache/cocoon/environment
AbstractEnvironment.java
src/java/org/apache/cocoon/environment/http
HttpEnvironment.java
Log:
Move extractAction method from HttpEnvironment into AbstractEnvironment,
add extractView method,
add setAction and setView methods.
This reduces code duplication with other environments.
