Key: BEEHIVE-71
URL: http://nagoya.apache.org/jira/browse/BEEHIVE-71
Project: Beehive
Type: Task
Components: Documentation
Versions: V1Beta
Reporter: Rich Feit
Assigned to: Steve Hanson
The netui-config.xml file, which lives in WEB-INF, contains webapp-wide
configuration settings for NetUI. Here are some short blurbs -- we can talk
more about the details of these, but I wanted to get this in here for tracking.
1) Action interceptors. <pageflow-action-interceptors>. If you want to be
notified before every action that's run in the webapp, you configure one of
these. A simple example of this is monitoring infrastructure that keeps track
of a count of actions raised -- you can register an interceptor that runs the
counting code before going to any action. A more complex example is an
interceptor that *redirects* you to another page flow before allowing you to go
to the current one; for instance, it might take you to a nested page flow that
asks you to fill out a "satisfaction survey" before sending you to the
destination page flow.
2) Handlers. <pageflow-handlers>. These settings let you override base
framework behavior. A good example is the LoginHandler. By default, we use
standard Servlet APIs to see if you're logged in, and we use some
server-specific APIs to actually log you in when login() is called inside a
page flow. If you want to replace this behavior with your own login scheme
(which may look at a User database table for login information), you can
provide your own LoginHandler that defines methods like login() and
isUserInRole().
3) PageFlow Config. <pageflow-config>. This is just the place for
settings that configure the page flow runtime across the webapp. If you want
to disable file-upload, for instance, you set the multipart-handler to "none".
There will be more settings here soon.
