Part of our java application needs to run javascript that is written by non-developers. These non-developers are using javascript for data formatting. (Simple logic and string concatenation mostly). My question is how can I setup the execution of these scripts to make sure scripting errors don't have a major negative impact on the rest of the application. Need to guard against infinite loops Guard against spawning new threads. Limit access to services and environment File system (Example: If a disgruntled script writer decided to delete files) Database (Same thing delete database records)

I'd like to use the Rhino JavaScript compiler to compile some JavaScript to .class bytecode files for use in a project. It seems like this should already exist, since there are groovyc, netrexxc, and jythonc tasks for Groovy, NetREXX(!) and Jython, respectively. Has anyone used or written such an Ant task, or can anyone provide some tips on how to write one? Ideally it would have some way to resolve dependencies among JavaScript or Java classes. Why not simply use java task? <java fork="yes" classpathref="build.path" classname="org.mozilla.javascript.tools.jsc.Main" failonerror="true"> <arg

By using Java Scripting API, I am able to execute JavaScript within Java. However, can someone please explain what I would need to add to this code in order to be able to call on functions that are in C:/Scripts/Jsfunctions.js import javax.script.*; public class InvokeScriptFunction { public static void main(String[] args) throws Exception { ScriptEngineManager manager = new ScriptEngineManager(); ScriptEngine engine = manager.getEngineByName("JavaScript"); // JavaScript code in a String String script1 = (String)"function hello(name) {print ('Hello, ' + name);}"; String script2 = (String)
