by an application start class or by code run within calls to the application. Application end
classes have the ability to create application or global data, though the concept of creating data
right before the application is released would seem pointless. The one situation where this would
be useful would be to set data that a subsequent application end class could use. For example, an
application start class could open up a database connection and store it in global data so that all
applications deployed on VXML Server could utilize the connction. This connection would need
to be closed, but if there are multiple applications with multiple application end classes, the
desire would be to close the connection by the last application to be released, in case the
application end classes need to use the connection. Each application start classes could increment
an application count value stored in global data that the application end classes would decrement.
The application end class that yielded a zero would know that it was the last application released
and so close the database connection.

The application end class action is built by implementing the Unified CVP class
EndApplicationInterface
found in the
com.audium.server.proxy
package. It contains a
single method named
onEndApplication
that is the execution method for the application end
class. This method receives a single argument, an instance of
ApplicationEndAPI
. This class
belongs to the Global API and is used to access and create application data and global data (see
the User Guide for Cisco Unified CVP VXML Server and Cisco Unified Call Studio Chapter 2 in
the section entitled Variables for more on application and global data). The method does not
have a return value. It is expected that should an unrecoverable error occur, the application end
class will throw an
