Launch WebPaint locally

[Dave]

Howdy,

I've tried experimenting with the WebPaint application locally on my
machine, but when I launch the demo, I get the following errors:

Demo: PaintWeb initialization failed.

Error: Failed loading the configuration file.

Does anyone know why this is? Is there something else I need to do in
order to get the app running locally?

Hello Dave!

To start PaintWeb you need a web server, like IIS or Apache. Web browsers
do not allow the loading of local files via XMLHttpRequest. The PaintWeb
code tries to load the configuration file and fails due to security
restrictions.

If you have a web server locally or remotely, simply copy-paste PaintWeb
there and you can start the demo.

Let me know if you have further questions. Thanks for trying PaintWeb!

Best regards,
Mihai

Hello,

 

Paintweb is an amazing tool that's exactly what I've been searching for but I can't get iit to work due to the initialization errors described by Dave in this thread. I'm running IIS 7.5 and get the exact same errors. Is anyone successfully running this on IIS 7.5 and if so, can you let me know what you had to do to get rid of the initialization errors? I changedf NTFS permissions to allow everything just to see if it was that, but no joy. The alerts are triggered in all browsers, not just IE 9 when running under IIS. Thank you.

Hi Mihai,
I tried the same option as you suggested. I am using Debian LInux. First of all I copied the PaintWeb directory inside /var/www/ directory and after giving the required permissions i am able to open PaintWeb directory from browser but when I try to run demos/demo1.html and click on the "Edit Image" button nothing happens at all. No Error and no Execution.

Please check the firefox web console for errors, and the network
monitor. [1]

You may also want to start the debugger and see where/why it fails.
Enable break on exception.

Good luck,
Mihai

[1] for web dev work I recommend you use firefox aurora or firefox
nightlies. they have much-improved devtools.
