According to the samples in cocoon 2.1.9 this is correct.

2. In my jxt file:

<ft:widget id="f1">
<fi:styling listbox-size="30" class="keyinbox"/>
</ft:widget>

Yep seems fine.

When I submit the form the validation works,
validation.captcha.mismatch, the only problem being that I don't know
how to display the generated captcha image that needs to be entered!!!
Do you or anyone else know how to do this?

Yes you can find this in the samples when you build cocoon 2.1.9.

Secondly is it possible to set properties of the captchareader in the
sitemap so as to control the height, width, background color, font type
etc etc etc of the captcha image and if so how can I do that?

Yes it is. I you use an SVG for the captcha image you can modify all these properties.

You will have to have something like this in your sitemap:

<!--
| Generate the CAPTCHA image. Any type of generator can be used here,
| as long as it reads the string to display from the session
| attribute named "captcha-{1}".
| Using an SVG file as input requires that the Batik block be

<map:match pattern="captchajpg">
<map:generate type="jx" src="captcha-image.xml">
<map:parameter name="value" value="{session-attr:captcha-{1}}"/>
</map:generate>
<map:serialize type="svg2jpeg"/>
</map:match>

With the following captcha-image.xml

<svg width="210" height="75">
<defs>
<filter id="blur2">
<feGaussianBlur stdDeviation="2"/>
</filter>
</defs>
<g id="imagegroup">
<text style="fill:#0086B3;font-size:42;font-family:Courier;filter:url(#blur2);" x="0"
y="48">#{$cocoon/parameters/value}</text>
</g>
</svg>

I hope this helps you out a bit more. It's best if you take a look at the samples in Cocoon. It will give you a nice
code overview of how to enable captcha for you website.

Reijn

CAPTCHA [1] might help. BTW, there is built-in support in cocoon. See
samples here: [2] [3].

Hi Jeroen,
right I am now generating an image but the image is just white, there is no
text to be read. What I have done is as follows:

sitemap:

<map:match pattern="captcha.svg">
<map:generate type="jx" src="jx/svg_captcha.jx">
<map:parameter name="value" value="{session-attr:captcha}"/>
</map:generate>
<map:serialize type="svg2jpeg"/>
</map:match>

svg_capture.jx:

<svg width="50" height="50">
<defs>
<filter id="blur2">
<feGaussianBlur stdDeviation="2"/>
</filter>
</defs>
<g id="imagegroup">
<text
style="fill:#0086B3;font-size:42;font-family:Courier;filter:url(#blur2);"
x="0"
y="48">#{$cocoon/parameters/value}</text>
</g>

</svg>

jx template:

<img src="captcha.svg" width="50" height="50"/>

What am I missing here? It seems that #{$cocoon/parameters/value} is not
working?!?

regards

Andrew

Hi Andrew,

What am I missing here? It seems that #{$cocoon/parameters/value} is not
working?!?

the code I copied into the previous email was just an example. Did you check out the cocoon samples?
Are you getting errors in your logs?

Could you check a couple of things:
- What cocoon version are you using?
- Is the svg2jpeg serializer defined in your application?
- Is the Batik block included in your application lib directory?

Regards,

Reijn
