I got a small question: (How) can I run some java code (preferable a jar) in its own JVM, in best case specifying my own libs. So for example to sandbox all file system access.
What of this stuff is possible, and how?

Do you mean "running some java code" within its own VM started from other Java code ? – Kartoch Apr 12 '13 at 15:28

yes, I want to run some java code in a sandbox launched and controlled from java – Kilobyte Apr 12 '13 at 15:33

1Its entirely possible. You will have to write the code though. It involves (optionally) writing your own classloader, installing a security manager, and defining a set of policy files. – Perception Apr 12 '13 at 15:35

To limit access to the file system or any other resource, make use of Java's Security Manager. See http://docs.oracle.com/javase/7/docs/technotes/guides/security/index.html for information on how to configure a policy.
