I'm trying to run envjs and Rhino in a java application to render SVGs with D3.js.
So far, I can evaluate smaller functions using Rhino but when it comes to setting up envjs, the problems begin. The most important one is that the only tutorial for envjs talks about a file called env.rhino.js. But I have no idea where to find it.
Can anybody help me out?
(Yes, google shows some results but they are not officially belonging to Rhino or envjs)

I know this answer is very late. But I want to do the same and had the same problems - maybe this will help the next one. It took a while to figure out which one of the hundrets of github forks on env-js will do the job. I found out that this combination will work for a simple test:
git clone https://github.com/thatcher/envjs-site.git
#note the different fork!
wget https://raw.github.com/thatcher/env-js/master/src/dom/sizzle.js
wget http://d3js.org/d3.v3.min.js
java -jar dist/env-js-1.1.jar
load("lib/env.rhino.js");
load("sizzle.js");
load("d3.v3.min.js");
d3.select("body").append("svg").selectAll("line").data([1,2]).enter().append("line").attr("x1", function(d){return d;});
document.innerHTML;
<html><head/><body><line/><line/><svg xmlns="http://www.w3.org/2000/svg"><line x1="1"/><line x1="2"/></svg></body><line/><line/></html>

I did attempt this but couldn't go very far. I also wanted to generate SVGs on server side, with requests being initiated from java(Glassfish in my case). The only way you can do this is with jsdom & Node.js. I am able to do this successfully. Sadly, other than Node.js + jsdom, there seems no other way to do this.
Once you get it working, there are bigger problems lurking if you try to heavily load Node.js with SVG generation requests.
First, download
env.rhino.js.Then, use this Java code to start a Rhino instance and load Env.js:
Now you can load and run a JavaScript file (using its absolute file-system path)
And/or evaluate JavaScript code and get its String result
