12/02/04

New architecture for the j2ee module commited : all the "business" logic has been mutualized in a JMX manageable ?ImageCaptchaService class. A Web service endpoint for axis has been created in the com.octo.captcha.j2ee.rpc package. You can find its axis deployment descriptor (.wsdd) in the src/conf directory. The web service need to be further tested, but it will be documented woth a user manual similar to the ImageCaptchaFilter one for the beta2 (or beta3 ?) release. It is also planned to unit test the ?ImageCaptchaService and to use it in a new version of the ImageCaptchaFilter.
10/02/04 Two new components commited : composedictionarywordgenerator and baffletextpaster to enable parc like jcaptchas.
