“java.security.AccessControlException: access denied” executing a signed Java Applet
Java

I have a little Java Applet and I have an annoying issue. I have signed my JAR with my own keystore using jarsigner tool (following these instructions).


The Java Applet downloads a signed JAR and tries to launch it with an extended class of URLClassLoader. This JAR tries to execute this line of code:


ClassLoader.getSystemClassLoader().getResource("aResource");

It fails with a large stack trace finished by:

java.security.AccessControlException: access denied using Java Web Start

I am having some issues with accessing files using JWS (Java Web Start). The program adds a new label and image. The program runs fine on my local computer but gives me pages of errors when I run the program on my remote server using JWS. Here's a sample of the error:
