[Mashup-user] Question regarding dynamically accessing classes within jars...

Hi Chad,

Axis2 (At the heart of the Mashup Server) has the ability to deploy a
POJO as a web service[1]. You will be able to use this approach to
expose your java classes and their functionality as web services.

In a Mashup Server deployment the 'services' directory is the place to
put your packaged java services. These will be deployed dynamically by
the server.

Once you have the necessary functionality of your java classes exposed
as services, you can use javascript to glue them together as required.
In other words 'mashing up' those services.

Hope this helps,
Tyrell
