Subject svn commit: r1676248 - in /openwebbeans/trunk/webbeans-web/src/main/java: META-INF/ org/apache/webbeans/servlet/
Date Mon, 27 Apr 2015 12:59:02 GMT
Author: struberg

New Revision: 1676248

URL: http://svn.apache.org/r1676248
Log:
OWB-1055 Split WebBeansConfigurationListener in Begin and End listeners

We need this as the order is the same for all init and destroy methods.
But CDI should get init as first listener, but destroyed as last.

Added:
    openwebbeans/trunk/webbeans-web/src/main/java/org/apache/webbeans/servlet/BeginWebBeansConfigurationListener.java
    openwebbeans/trunk/webbeans-web/src/main/java/org/apache/webbeans/servlet/EndWebBeansConfigurationListener.java
