The <jsp:useBean> action places a reference to the bean in the specified
scope, or the page scope by default, using the name specified by the id
attribute.
So your custom action could look something like this:
<foo:myAction name="bean" ... />
The name attribute specified the name of the bean you like to use,
and your custom action implementation can search for it in all scopes
using the methods of the PageContext class (always available to a
custom action).
If the custom action can deal with beans of different types, it can
use "if (theBean instanceof AClass)" tests to do different things
depending on the type of the bean, or use introspection to look for
required methods in the bean, etc. What's right here depends on what
the custom action is designed to do.
