Here is the error:

Answer 1

Are you using external policy file ? By default policy file would be picked from user.home/.java.policy System wide policy file will be from java.home/lib/security/java.policy

Looks like this you are using external policy file which you have to pass to the program by using the following property. -Djava.security.policy=mypolicy

In netbeans you have to pass this by in VM Arguments section under Run

Hope this would solve the issue.
