rhino

I'm starting to run into the dirty little secrets of what is an otherwise very useful JSR223 scripting environment. I'm using the builtin version of Rhino shipped with Java 6 SE, accessing it through JSR223's ScriptingEngine et al. When I get an exception caused by a Java object I've exported into the Javascript environment, it is a ScriptingException that wraps a sun.org.mozilla.javascript.internal.WrappedException that wraps my real exception (e.g. UnsupportedOperationException or whatever) The ScriptingException returns null for getFileName() and -1 for getLineNumber(). But when I look at

Some JavaScript files that have been developed for Rhino's shell use load() to load additional JavaScript files. I'm attempting to embed functionality from one of these Rhino JavaScript files using javax.script. Unfortunately, the load() function is not implemented by javax.script's JavaScript. When attempting to eval() a script containing load(), the following error occurs: com.sun.script.javascript.RhinoScriptEngine:-1:in `eval': javax.script.ScriptException: sun.org.mozilla.javascript.internal.EcmaError: ReferenceError: "load" is not defined. Does javax.script provide a for the load()

I have run into an issue that I believe is rooted in the implementation of anchor tags in Rhino. Although I am utilizing env.js , I suspect perhaps I am not configuring something correctly. In particular, my issue occurs while I am attempting to write unit tests against code written for an angularjs application. When I include angular.js (versions 1.2.1 to present), I get the following error: TypeError: Cannot call method "charAt" of undefined I am convinced the error is the result of this call to urlParsingNode.pathname since a console.log call reveals that the pathname object is undefined. I

I have some javascript files and parse it using Rhino's javascript parser. but I can't get the comments. How can I get the comments? here's a part of my code. run this code, "comment" variable has null. also, while running "astRoot.toSource();", it shows only javascript code. no comment included. it disappeared! [java code] public void parser() { AstRoot astRoot = new Parser().parse(this.jsString, this.uri, 1); List<AstNode> statList = astRoot.getStatements(); for(Iterator<AstNode> iter = statList.iterator(); iter.hasNext();) { FunctionNode fNode = (FunctionNode)iter.next(); System.out.println

Basically I'm trying to pass a javaScript function to a Java method to act as a callback to the script. I can do it - sort of - but the object I receive is a sun.org.mozilla.javascript.internal.InterpretedFunction and I don't see a way to invoke it. Any ideas? Here's what I have so far: var someNumber = 0; function start() { // log is just an log4j instance added to the Bindings log.info("started...."); someNumber = 20; // Test is a unit test object with this method on it (taking Object as a param). test.callFromRhino(junk); } function junk() { log.info("called back " + someNumber); }

I'm using Rhino 1.6r2 through the javax.script API. I know that the Rhino engine claims to be MULTITHREADED: "The engine implementation is internally thread-safe and scripts may execute concurrently although effects of script execution on one thread may be visible to scripts on other threads." What I'd like to know is, under what exact conditions would the effects of one script execution be visible to another? In my code, I sometimes re-use a ScriptEngine object, but for every execution I create a new SimpleBindings and pass it to eval(String, Bindings) . With this arrangement, is there any
