JCaptcha tries to strictly respect the Inversion of Control pattern, to ease creation of components for concrete applications.
On the other side the Spring Framework allows to use the power of IOC combined with XML declarations.
So that, every single component of jCaptcha can be declared in XML, and instanced through Spring.
An
application using jCaptcha should only manipulate a CaptchaService instance.
