scripting - java expression language that can't access 'unsafe' java methods -

-

I am working on a project where I will send users 'small' scripts to the server, and I execute those scripts Will do There are several scripting languages ​​that can be embedded in Java programs, such as mvel, ognl, eul, closer, rhino javascript, etc., but as far as I can tell, they allow all script writer Java constructors to call , Static methods, etc.

I do not want my users to be able to call anything that I do not provide them (usually through any reference item) most of their script will be arithmetic and logical expression, in some cases They have to find the object properties (gates / sets) or the contents of the map. I do not want them to escape from the sandbox.

Any suggestions?

I think you can get it by the use of A.

In addition, I've never heard about the amount of storage or storage taking in large amounts, so I'm not sure whether there is any reason for the alarm or not. If you are seeing a potential problem, then I would suggest running an update before, if it does not clean it, it is leaving and then it appears to be safe operation (because it is the only query optimizer Is for). I will not leave "left" in the
