Hello,
I am trying java web start for my gui application and keep getting this error: java.lang.reflect.InvocationTargetException
Below it states that it is caused by the static initializer error, which i have no idea how to fix.
Furthermore, i have already signed the jar file with a self made certificate, and still get a java.security.AccessControlException
I'm stumped and would appreciate any help. Thanks in advance.

Have you set the security element in your jnlp file?
