Denis, The hivemodule.xml file for Tapestry-Captcha will take care of wiring in the linkFactory and imageCaptchaService.
James -----Original Message----- From: Denis McCarthy [mailto:[EMAIL PROTECTED] Sent: Wednesday, October 04, 2006 11:08 AM To: Tapestry users Subject: tapestry-captcha/acegi integration Hi, I'm attempting to integrate James Carman's tapestry-captcha library into a proof of concept app I'm putting together. The acegi stuff is redirecting correctly to a very simple captcha page just containg a reference to the captcha component from tapestry-captcha. Here's the .page: <page-specification class="org.apache.tapestry.html.BasePage"> <component id="captcha" type="captcha:CaptchaImage"></component> </page-specification> However, when the app jumps to this page, I'm getting a null pointer exception in the getLink() method. After looking at the code in the CaptchaEngineService class, it seems like I need to define both a LinkFactory and an ImageCaptchaService for the component. I haven't messed with services before, so I'd like to know how to go about defining a linkfactory for this component?. As I'm using Acegi, I'd like to use acegi's CaptchaValidationProcessingFilter to process the captcha's success or failure. This filter uses the presence of a validation parameter (defined in the spring application context) to decide whether to validate the request or not. Is it possible in tapestry to ensure that the validation parameter passed back in the http request has a specific name, so that the filter will pick it up and validate whether the captcha was correctly entered? If anyone needs any further info just ask TIA Denis Mc. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
