A.2 Extensions

In this section, you will find the configuration parameters for Stripes
extensions: classes that implement all subinterfaces of Configurable-
Component , as well as Formatter and TypeConverter implementations. If
you specify the Extension.Packages parameter shown next, all the follow-
ing parameters are optional. Use them only if you prefer not to have
your implementation automatically loaded by the extension packages
mechanism.

Extension.Packages
This parameter is optional but highly recommended. By specifying the
packages where your Stripes extensions live, you can add, change, and
remove extensions in those packages without having to make any other
configuration changes. Stripes automatically loads all extensions from
those packages unless you've marked them with @DontAutoLoad .

For example:

<!-- Only one package root -->
<init-param>
<param-name> Extension.Packages </param-name>
<param-value> stripesbook.ext </param-value>
</init-param>

<!-- Multiple package roots are separated with commas -->
<init-param>
<param-name> Extension.Packages </param-name>
<param-value>
stripesbook.ext,
org.stripesstuff.stripersist
</param-value>
</init-param>

ActionBeanContextFactory.Class
This is the implementation of the ActionBeanContextFactory interface,
which is responsible for creating ActionBeanContext objects.
