Reply #17 - May 4^th, 2009, 1:43pm I have followed both the instructions on the Krister website and also in the Hacks section, It says that it has signed the applet, yet it still wont show up in the web browser. I have no idea what is going on.

Reply #19 - Dec 4^th, 2009, 10:43pm Hi, Okay, so I did all of that as instructed, however now when I run the app, I get a message to sign it, and when I try to sign the app I then get this error message: "The publisher cannot be verified by a trusted source. Code will be treated as unsigned." The app does not sign, and does not run! Why? Arg!

Part 1... I am using a video capture example from processing... the BrightnessTracking..

It works ok in Processing IDE

I exported the sketch and signed all the *.jar files in the applet folder

the proyect does not work even with the signed *.jar files

which are..
1) core.jar
2) video.jar
3) brightnessTracking.jar

This is the error code displayed in the java console

Code:

Hi,
The heads up on needing to sign applets using Ess is great, because i thought i had finally figured out why my sketch wouldn't load online but not that i have followed the instructions in signing the .jar files through the terminal it doesnt seem to have helped? the sketch doesn't run, when exported and put on the browser?

any thoughts?

hi,

i signed all the *.jar in the applet folder, when i start the index.html, it opens in the browser and asking to accept the licens. ---> ok
but the sketch doesnt work full. i cant get the audio input from browser.
is it possible that minim cant get audio input when opened in a browser??

i get this in java console:
Code:

==== JavaSound Minim Error ====
==== Error acquiring TargetDataLine: access denied (javax.sound.sampled.AudioPermission record)

ControlP5 0.3.14 infos, comments, questions at http://www.sojamo.de/libraries/controlP5
### WARNING AccessControlException.
you are probably running in applet mode.
make sure fields and methods which you want to 
access in your processing code are public.
java.security.AccessControlException: access denied (java.lang.reflect.ReflectPermission suppressAccessChecks)

SOLVED

the reason was ---> no permission to acces audio input!!
ad this to your java.policy

Code:

permission javax.sound.sampled.AudioPermission "record";

you have to be admin to save the java.policy file,into the file %JRE_ROOT%\lib\security\java.policy on the client computer, where %JRE_ROOT% is the installation path of JRE.

then signe the *.jar's again .
and it will work perfect.

thanks for that extra info Maik

on a separate note, i noticed that Wordpress doesn't like signed microphone input applets, even though they work in a separate HTML file.

haven't yet figured out why though.

to be honest, signing all the .jar files is a right pain in the ass. the java developers definately didn't go through this process many times, or they would've found a more human friendly way to do it. i love processing, but Java's web implementation is pretty damn shoddy and klunky. I live in hope of ProcessingJS.

would be nice if someone wrote an application, where you could drop a folder onto it, filled out the info and it signed all the files.

I am.
