Custom STS cannot load custom issuer

A: Description of Problem
When creating a custom STS service as instructed by the documentation at the site:
http://axis.apache.org/axis2/java/rampart/setting-up-sts.html
and invoking the service, a 'class not found' exception is thrown. Therefore the token dispatcher cannot
call the issue() method of the custom token issuer.

B: Tests:
If one performs all the tasks above and replaces the custom token issuer with the default rahas token
issuer, the default issuer is successfully loaded.

C: Addtional information:
The documentation states to remove the rampart module. Those instructions are clearly in error. It is
assumed that the module to removed is the rahas.mar module.

D: Workaround:
The approach I am taking requires the Rahas/Rampart source distribution. In this case I implement my
custom token issuer in the same impl package as the default token issuer. Then I modify the rahas.mar
file to point to my custom issuer. In my case I am writing an issuer for a SAML20 token so I replaced
that issuer. The new class file needs to be added to the rahas-1.6.2.jar in the axis2/webapps/lib directory.

E: Remark:
There is probably a simple step missing from the documentation preventing me from implementing the
custom issuer as intended. I also noted callbacks in the source code but I could not find any
documentation on how to use them; though they may not be intended for applications.
