Thanks again James.
I see what you're saying, but the fact is that I _am_ getting an NPE
when calling a method on the LinkFactory in the CaptchaEngineService,
and the LinkFactory within the Service is indeed null (meaning that it
is not getting wired up, I assume). I'm sure I'm missing something in my
app that's causing this, but I don't know what.
I'm using tap 4.1. I thought that might be the problem (as
tapestry-captcha has 4.0 as a dependency in its pom) But I get the same
exception in CaptchaEngineService when I try it with 4.0.
If anyone knows of any error that would cause hivemind not to wire up
services properly I'd be more than grateful - I know this is something small
TIA

HiveMind doesn't require you to explicitly set your properties. It has an
"autowire" feature. So, HiveMind will set those properties for you just
becuase it has service points defined which implement those interfaces.
Tapestry-Acegi is not very well documented currently, but it's not really
rocket science. All I did was set up the servlet filters as HiveMind
services and create a mechanism where you can supply servlet filters as
web request servicer filters (it wraps them and plugs them into the
pipeline). I didn't want to rewrite all of the servlet filters that Acegi
is based upon, so I came up with the bridging idea and it seems to work
out well. I plan on doing more work, like setting up form-based
authentication and giving examples of all of the setup options.
where did you find any documentation on tapestry-acegi ? I tried using it
breifly, but gave up as I couldn't find the source or any documentation.

Thanks for the response James. The relevant part of the hivemodule.xml
in the version I downloaded looks like this:
<module id="tapestry.captcha" version="1.0.0">
.

.
<service-point id="CaptchaEngineService"
interface="org.apache.tapestry.engine.IEngineService">
<invoke-factory>
<construct
class="com.javaforge.tapestry.captcha.service.CaptchaEngineService">
<set property="mimeType"
value="${tapestry.captcha.mimeType}"/>
</construct>
</invoke-factory>
</service-point>
.

</module>
As you can see there is no LinkFactory set for the CaptchaEngineService
here. When I step through the code in the CaptchaEngineService prior to
the NPE, the LinkFactory is indeed null. Am I missing some extra
configuration or something?
Thanks for your help

Denis,
The hivemodule.xml file for Tapestry-Captcha will take care of wiring
in
the
linkFactory and imageCaptchaService.

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.
