i was just trying to follow johnG's doc to create a website for an app that uses opengl online but still i havent got it to work.. looking into java console this is the error i get:

Code:

it breaks write on the first try to load an image as you can see.
im using TextureIO to load textures into opengl (not using PImage).

i was wondering if anyone knows how to work with the file permissions problem.

NOTE: this does not work online, neither it works locally in my PC. its the same error.

thanks in advance

koogs,

i found that null weird aswell but im not sure what it can be.

the files are in data folder as processing wants it to be, that means a folder called \data inside the sketch folder.

when i export the applet ive placed data folder inside it too, i think that should work.

as for how do i load the files?
i tried 2 ways and none worked for me:

Code:

image = new Texture( "imagename.jpg" );

and

image = new Texture( dataPath("imagename.jpg") );

 

the files are there yes and i have read permissions for every folder in my server.

but as it does not work locally in my PC, i think the problem might come from somewhere else. just not sure where from :/

do u have any idea that i could try to see if it works ?

ok i have fixed it by calling TextureIO.newTexture() URL method instead of the File.

the problem is that everytime i want to put a sketch online i have to change the way i load my files :/

i use Ess to load samples and it works just fine. would be cool to know how they load the files using File
