security problem with Java ScriptEngine

问题:

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);

回答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.

Use the Java Security Manager. Refer this answer for an example.

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.
