[jala] captcha broken?

[Anton Pirker]

Hi!

I hope i also can ask jala questions in here.

I just wanted to add a jala.Captcha() to my app and it did not work.
First thing was, that the jcaptcha jar file was missing.
I downloaded the latest version, changed the filename in Captcha.js and
tried again. Again no luck.

Captcha.js uses Packages.com.sun.image.codec.jpeg.JPEGCodec which seems
not to be available in OpenJdk Java 1.6.0-b09.

So i changed the code to use javax.imagei like this:

    /**
     * Render a new captcha image.
     */
    this.renderImage = function renderImage() {
       var image = captcha.getImageChallenge();
       var stream = new java.io.ByteArrayOutputStream();
       javax.imageio.ImageIO.write(image, "jpg", stream);
       res.contentType = "image/jpeg";
       res.writeBinary(stream.toByteArray());
       return;
    };


Now it works!
Maybe some of the jala folks can add this changes to the repository?

thanks,
Anton

hey anton

thanks for the suggestion which i hardly noticed due to some helma-
user mails not coming through.

regarding the missing jar this is communicated at the jala site [1].  
(should this be more prominent?)

and would you mind creating a ticket at [1] with your patch attached?  
we'd be very happy.
:)

ciao,
tobi

Hello Anton,

Why not just rely on Helma's internal image saving mechanisms? They  
would use whatever is available on a given system...

oh. yes that should be definitely more promiment. i suggest it should be
mentioned here:

https://dev.orf.at/trac/jala/wiki/JalaModules#Captcha

i have created a ticket, but there was an error while uploading the
attachment (permission denied to store the image) so i added the svn
diff in the ticket-text.

i moved the note to the url you suggested. i agree it's the better spot.

btw. i think the license restriction does not apply anymore, anyway,  
as the developers went back to lgpl just a few months after  
jala.captcha was released [1].

will post a ticket about that later.

oops, thanks anyway, for both trying to add an attachment and letting  
me know that it does not work.

i fixed the permissions for the trac attachment directory and uploads  
are working again.

furthermore, i extracted the patch you provided in ticket #88 and  
added it as attachment to ticket #87 [2].

ciao,
tobi
