security problem with Java ScriptEngine

Question

I just started to use the Java ScriptEngine to do little extensions to my Application then i noticed that i can import all the java classes in the script and use them without restrictions. Is there a way to specify what classes a script can use? I dont want them to do things like java.lang.System.exit(1);

Well, you seem to need to learn about the Java SecurityManager. That's a pretty large topic, you might want to read up on it and then post a more specific question if you have trouble making it work for you.

SecuritiyManager sounds good i will look at it. Do you have any hints for me where to start on this big topic? – lucidd Dec 10 '09 at 13:18

I solved this by putting "importPackage = null" on the top of all scripts, it seems to work but Im not sure if this hack can be avoided.

looks like this is the easiest way to restrict all importPackage calls – webber Sep 18 '13 at 00:12

In this case it is still possible to do something like this: `java.lang.System.exit(1);`. Program will exit. – Клаус Шварц Aug 26 '17 at 05:40
