Hi Hamish,

Thanks for the info, I'll try to reproduce this asap. I'll let you know how it goes

Warm regards,
Sam

Hi Hamish,

So basically we didn't change any code relating to the captcha in the new version. Out of curiosity, did you set a variable somewhere called java.awt.headless, because Ubuntu Server is a headless OS?

Warm regards,
Sam

Hi Hamish,

Here are all the possible Captcha settings that you can specify in portal-ext.properties. Perhaps you should try enabling recaptcha's captcha service? (http://www.recaptcha.net) -- if ours doesn't work for you maybe theirs will. I'm still unable to reproduce the bug right now.

To use this, copy any properties you think you want to change (what you see here is default) and modify them as willed in your portal-ext.properties, which you probably have created already. If not, it's in tomcat-{version}/webapps/ROOT/WEB-INF/classes/portal-ext.properties

In fact, I'd recommend using recaptcha. It's a really great service and to activate it just add this to your portal-ext.properties (you need to get your own public/private key though)

Thanks Sam, looking into it now.

One thing we did which might affect it, we installed a new copy of Liferay 6.04 on our server and imported the database from our 6.03 build, we also downgraded our operating system form Ubuntu server 10.04 to 8.04 in the move.

Hi Sam,

I'm part of VisionOn.tv and did the server setup. First thing to say is I'm no expert.

All I did with java was: sudo apt-get install openjdk-6-jre
As java runtime installed it reported it was installing 'headless', we did no other configuration of java.

We'll probably want to try with recaptcha for better accessibilty. I read somewhere Recaptcha is enabled in liferay 6? What wasn't clear to me was whether we needed to create an account with recaptcha.net or if it somehow functions 'out-of-the-box' as part of Liferay? You've answered that for us already, so we'll sign ourselves up for a key.

Thanks

[Samuel Liu，修改在13 年前。]

Hi Steve,

Yeah I would think it installed as headless if you used apt to get it. Hrm, yes Recaptcha is plugged in out of the box, so go ahead and add those properties to your portal-ext with your keys. Hopefully this will solve your problem.

Alternatively you can also disable captcha, though I doubt that's optimal.

A part of me wonders if SimpleCaptcha's failure to render a captcha might have to do with the fact that Ubuntu server doesn't come with graphical utilities. There may be an unaccounted for dependency -- I can do a test on this but it will take some time. Until then your best bet is Recaptcha I think. (I also prefer recaptcha -- the captchas tend to be clearer and it's Google technology so it's rock-solid).

Let me know how it goes!

Warm regards,
Sam

[Hamish Campbell，修改在13 年前。]

Sam, thanks for the excellent help, Steve got Recaptcha up and running which has solved the problem.

Hi,
I have the same problem in Liferay 5.2.3. On my pc, which runs on Ubuntu 10.04 with GUIs, captcha was showed. When I installed it on a server, which runs on Ubuntu server 10.04 LTS, in command-line modality, the captcha stopped to work.

Do you think this problem is due to "headless"? Do I have to install further libraries, like java.awt.headless?

Thank you!

Furthermore, is there a mechanism to use recaptcha service in Liferay 5.2.3 or a way to integrate it?

Bye

Tina

[James Falkner，修改在13 年前。]

I don't know if this will work but in the past on headless systems one had to set -Djava.awt.headless=true on the JVM command line (or through code) to keep the graphics subsystems from throwing exceptions when GUI libraries weren't present.

Hi Tina,

I am also facing the same problem. In my local meshine captch is showing properly,
but in server it is not showing.
I am using liferay 5.1.2 with tomcat 6.0
Have you solved your problem, if it solved can you share with me how you solved.

Thanks,
Satish.

As this thread seems to stay on top in the "Recent Changes" I'll add some explanation: I've split an unrelated new question (that resurrected this thread) into its own thread. Please continue there - back to sleep for this old thread.
