I recieved a question about CAPTCHA integration in Struts2 based on AppFuse integration at my personal email and thought I should post the response here, since this is where all the appfuzers hang out and the answers may help others. --Jason
========================== Hi Daniel, I'm glad to have a go at helping you, but just keep in mind that either the Octo.com or Appfuse.org support channels may be more informative. The AppFuse framework can be based on Struts2, and that's what my example code on appfuse.org uses. You don't need the full-blown AppFuse meta-framework to make it run. In fact, the nice thing about AppFuse is that you can pick and choose what frameworks you do want to use, and it's an excellent example of how to integrate them.... So, though you've got an "imposed framework architecture", you can still use AppFuse to get this code running and then transfer it over to your model, using AppFuse as an example. Other answers are inline below. regards, Jason On Tue, Mar 18, 2008 at 8:07 AM, Daniel Varrin <[EMAIL PROTECTED]> wrote: > Hi Jason, > > I saw on http://appfuse.org that you could implement a captcha using > appfuse > in a struts 2 project.

"imposed frameworks" are pretty common, don't let it get you down :) > > Do you know how can I load a BufferedImage from a tag? Yes, you can do this with a servlet like so: captcha.jpg " name="captcha" /> Note: the servlet is literally mapped in the web.xml as "captcha.jpg". There is no image on the filesystem called captcha.jpg - it's the servlet that is rendering this image because of the servlet mapping: <servlet-mapping> <servlet-name>captcha</servlet-name> <url-pattern>/captcha.jpg</url-pattern> </servlet-mapping> > > I was following the procedure explained here: > http://forge.octo.com/jcaptcha/confluence/display/general/5+minutes+application+integration+tutorial, > but I was not able to make it work. Hum, I haven't followed that documentation.

If you aren't using Spring, you'll have to create a servlet init() method that will configure the ImageCaptchaService properly as a member variable of the ImageCaptchaServlet. Basically, you need to use all of the class files in the Spring example for the AppFuse CAPTCHA service, but code them in Java instead of XML. > Is it possible to call an action that will return the picture and use this > result in the "src" attribute of the tag? > Yes, you can do this using Struts (v1 or v2). It would do the same thing that ImageCaptchaServlet does though. Basically all you get is the ability to move the configuration of captcha image rendering from the web.xml into the struts.xml. This would be a good idea if everything you were doing was within Struts. > I hope you will be able to help me. > I hope it helped. :) > > Best regards, > Daniel Varrin > [EMAIL PROTECTED] -- View this message in context: http://www.nabble.com/Re%3A-Captcha-in-Struts2%2C-and-AppFuse-tp16125363s2369p16125363.html Sent from the AppFuse - User mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
