controlP5 error onOpenProcessing

in Contributed Library Questions • 9 months ago

Hi I used to run this sketch on OpenProcessing with no problem. I now get this error:

java.security.AccessControlException: access denied ("java.lang.reflect.ReflectPermission" "suppressAccessChecks")

Exception in thread "Animation Thread" java.lang.ExceptionInInitializerError

at WormsEnglish06.setup(WormsEnglish06.java:130)

at processing.core.PApplet.handleDraw(Unknown Source)

at processing.core.PApplet.run(Unknown Source)

at java.lang.Thread.run(Unknown Source)

Caused by: java.lang.NullPointerException

at controlP5.BitFont.<init>(Unknown Source)

at controlP5.ControlP5.<clinit>(Unknown Source)

... 4 more

java: 130 is cp5 = new ControlP5(this); to initialize controlP5.

Setting all controlP5 objects/function to Public doesn't solve it. The sketch is still running ok under Processing 1.5.

Any idea to get this solved plz?

Hi, which version of controlP5 are you using? If it is 1.5.2 i can trace back the error message to a reflection operation inside class BitFont line 58-71, here java's security measures take action where at this point I can't do much.

Since applets are not supported with processing 2.0 anymore ( see this blog post on openprocessing No more applets with processing 2.0a7 and wiki.processing.org/w/Changes under The Big Stuff ) I can only suggest to use a processing pre 2.0 version in combination with controlP5 version 1.5.1 or even earlier (see download list code.google.com/p/controlp5/downloads ) to create and upload your applets.

Hi Andreas and thanks for your very informative answer.

Thanks also for your very useful libraries!

Yes, I was using version 1.5.2.

I just tried to upload a version using controlP5 version 1.5.1. I'm getting new errors... see here

Can I use version 0.7.6 with processing 1.5.1?

I didn't follow much the changes since processing 2.0 as most of my sketches run much slowlier... Do you intend to port controlP5 to ProcessingJS?

What about SDrop? Is it usable with Processing 2.07b?

Hi,

with processing 1.5.1 you can use any version between 1.5.1 and 0.3.14.

SDrop works with 2.0b7. examples that make use of the File class will tell you that class File can't be found though, to fix this you need to add which is not automatically added by processing with this version anymore.

Copy code

import java.io.*;
