Java Scripting Engine importing my classes does not work
java, scriptengine
Solution
After looking at the Mozilla Rhino docs, the solution is either to use:
`importPackage(Packages.jasim)` within the script, or to use `new Packages.jasim.JSTest()`
This is not so clear in the Sun docs regarding the importPackage in the ScriptingEngine docs.
Problem
A code is worth 1000 words of explaining it :-) ``` package jasim; import javax.script.ScriptEngine; import javax.script.ScriptEngineManager; import javax.script.ScriptException; public class JSTest { public static void main(String[] args) throws ScriptException { ScriptEngine jse = new ScriptEngineManager().getEngineByExtension("js"); jse.eval("println(new jasim.JSTest().toString)"); } @Override public String toString() { return "JSTest Object"; } } ``` This code will fail with the below exception: ``` Exception in thread "main" javax.script.ScriptException: sun.org.mozilla.javascript.internal.EcmaError: ReferenceError: "jasim" is not defined. (<Unknown source>#1) in <Unknown source> at line number 1 ``` How do I import my own classes into the ScriptEngine?
