svn commit: r106447 - in struts/sandbox/trunk/struts-shale: . src/conf src/java/org/apache/shale/faces
Author: craigmcc
Date: Wed Nov 24 11:25:18 2004
New Revision: 106447
URL: http://svn.apache.org/viewcvs?view=rev&rev=106447
Log:
Implement the mechanism for application-wide controller actions (as described
in the original Shale proposal), by virtue of turning the filter's processing
into the execution of a Commons Chain chain. The standard behavior can be
customized in two different ways:
* You can completely replace the "standard" command in the "shale" catalog
with something of your own devising. Note that you'll likely want to use
something like the InvokeCommand command included in the standard chain
to invoke the remainder of the servlet container's filter chain.
* You can define your own "preprocess" and/or "postprocess" commands in the
"shale" catalog, which will be invoked before, or after, the remainder of
the servlet container's filter chain, respectively. If you have commands
in the preprocess chain, you can do things like an HTTP redirect and then
return true (which tells Commons Chain that the request has been completely
processed), so that all remaining activities will be skipped.
As Shale initializes itself, it determines whether the application has already
set up a "standard" command in the "shale" catalog. If not, it configures this
command based on a "shale-config.xml" file embedded in the JAR. This does not
require any extra configuration work by the application developer.

+ * <p>The detailed processing to be performed for each request is configured

+ * Resposibility" design pattern, as implemented by the Commons Chain package.
+ * There must exist a <code>Catalog</code> named <code>shale</code>, which

+ *
+ * <p>At any point, one of the <code>Command</code>s being executed may choose

+ * <p>The default implementation of the standard command processing chain
+ * performs the following tasks:</p>
+ * <ul>
+ * <li>Invoke a command named <code>preprocess</code> (in the <code>shale</code>
+ * catalog), if it exists. This is where you should insert commands to be
