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:


Caused by: java.security.AccessControlException:
access denied ("java.lang.RuntimePermission" "getClassLoader")

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:
