WebWork came out in March 2002 with the goal of improving Struts 1 and adopting the best ideas from other frameworks. In December 2005, the WebWork and Struts communities joined forces to create the Struts 2 framework.

We have earned a reputation for shipping software that is long on features and short on defects. </p> + +<p><strong>Flexibility.</strong> The Struts 2 framework is designed to be pluggable from the ground up. The controller's lifecycle can be customized for each application, and even for each action within an application. The tag library is stylesheet-driven and easy to customize, either all at once or tag by tag. Struts 2 does what you want it to do, but <em>only</em> what you want it to do. </p> + +<p><strong>Performance.</strong> From field experience, we know that Struts-like, action-oriented frameworks perform well and are maintainable. </p> +</div> + </div> + + + </div> +</div> +<div class="footer"> + Generated by CXF SiteExporter +</div> +</body> +</html> http://git-wip-us.apache.org/repos/asf/struts-site/blob/124e36c4/content/docs/cdi-plugin.html ---------------------------------------------------------------------- diff --git a/content/docs/cdi-plugin.html b/content/docs/cdi-plugin.html new file mode 100644 index 0000000..1113c32 --- /dev/null +++ b/content/docs/cdi-plugin.html @@ -0,0 +1,539 @@ +<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd";> +<!-- +Licensed to the Apache Software Foundation (ASF) under one +or more contributor license agreements.
