is a step beyond the 001 version. It more fully integrates the applications
with the topology model. In particular with this patch you must explicitly
reference an application for it to be deployed. Here is an overview of how it
works.
First you need to have an application in {{conf/applications}}. This can
either be an exploded WAR format directory that contains and application or a
WAR format archive file. So you may for example have sample.war stored there
{{conf/applications/sample.war}}.
Next you would reference the application from within a topology file. This
reference is made via a new {{<application>}} tag. A subtag {{<name>}}
identifies the name of the application from within {{conf/applications}} to be
deployed. So consider a topology file {{conf/topologies/green.xml}} that
contained this:
{code:xml}
<topology>
<application>
<name>sample</name>
</application>
</topology>
{code}
This would deploy the application from {{conf/applications/sample.war}} and
make it available at {{https://localhost:8443/gateway/green/sample}}. The
current convention being that the base name of application is used as the
context path.
A few things to note:
1. Currently a topology file can contain only a single application.
2. Currently a topology file can contain only a single application or services.
All of the the provider features configured via the {{<gateway>}} section of
the topology file can be used and will be applied "in front of" the application
processing.
The application directory/archive (e.g. {{conf/applications/sample.war}} or
{{conf/applications/sample}} can contain {{service.xml}} and {{rewrite.xml}}
file identical to those used by service definitions. If these are not found
defaults are provided. For {{service.xml}}, essentially all routes are mapped
(i.e. {{/?\*\*}} and {{/\*\*?\*\*}}). For {{rewrite.xml}}, no rules are
defined.

> I think that we need the ability to serve up arbitrary web app resources.
> Given a conf/applications along side conf/topologies, we should be able to
> spin up a simple application that can be used as a central login facility
> with KnoxSSO, a management UI or any number of simple applications.
