rhino

Here is my situation: I have access to a Rhino Context object in a Java class. I want to read in a bunch of .js files and pass them along to the Rhino context to have them evaluated. I'm not really interested in having the functions in the .js files available in the scripting context so much as I am in just having the variables that are declared in the .js files available (this is a tooling validation kind of issue). Ideally I would read in and try to evaluate each file all at once, not line by line. I noticed there is a method in Context (see Rhino API ) called evaluateReader() . My first

I'm looking for a way to start playing around with Oracle's new Nashorn JavaScript Engine. I've DL'd the latest OpenJDK 8 (b65) and it appears that Rhino is still the only included script engine. Anyone know when (or in which build) Nashorn will replace Rhino in the OpenJDK? Or even better, where I can get a JDK with it included already? I know Netbeans has already written a debugger to use it, just not sure where they got the libraries/code to start writing it. Anyone have some links? Thanks. It looks like there is no sign of Nashorn on OpenJDK yet. The most recent comment from Jim Laskey in

In JDK6, is there a way to load multiple scripts, each in a file, and have the one script reference a method of another script? Sort of like "include"? I think you're after the load() method/property of Rhino's global object/scope load("file1.js"); load("file2.js"); load("file3.js"); methodFromFileOne(); var bar = methodFromFileTwo(); var etc = dotDotDot(); This will load a javascript source file, similar to how include/require will in PHP. Once you load a file, you'll be able to call and function or use any object defined in the loaded file. This is how things work when you're using the Rhino

I was trying to pass a String object that represents a JSON string from java to javascript function using ScriptEngine in jdk 1.6. My code works in JSFIDDLE http://jsfiddle.net/hn4yk/13/ but when I try to load it with the ScriptEngine it doesn't work and throws an exception sun.org.mozilla.javascript.internal.EcmaError: TypeError: Cannot read property "resultList" from undefined (#1164) I tested that the variable is passed correctly but the eval or the JSON.parse method doesn't work! I tried to put the library for JSON.parse and my function in the same file! This is my java code: public class

I'm trying to improve the performance of a javascript snippet evaluator . These script snippets can reference any number of variables that exist in a string-keyed map of json-like object graphs (IE: Json AST). I'm using JDK 1.6 and the embedded Rhinoscript engine (v1.6R2). Currently, processing takes the form: Snippet is parsed to discover the names of referenced variables Variables are retrieved from the map and serialized to a json string Json string is assigned to a similarly named variable at the start of the script Evaluate augmented script I'm trying to figure out how to skip the json
