FAQ
What is the performance between Rhino JS and native Java
Rhino JS is significantly slower in run-time than native Java. Even when Rhino is pre-compiled with high optimization, it still is still no match for a compiled Java program.
How long are private pointers?
2-byte aligned check the JSVAL macros at the top of jsapi.h
Can I call functions in Mozilla extensions from web page?
No, accessing anything in the web page's script may lead to security problems.
Newly created threads in JS from MOZILLA_1_8_BRANCH causes to hang in Windows
This Patch should fix the problem.
After that, recompile JS and define JS_USE_ONLY_NSPR_LOCKS in the build.
How to determine Rhino version programatically?
You can call getImplementationVersion() on a Context instance and it gives you a string
eg. Rhino 1.6 release 2 2005 09 19
Can an embedded SpiderMonkey JS Engine use DOMParser extension of Mozilla?
DOMParser is not part of JS but part of Mozilla browser which makes it available to script in the browser using XPConnect. An alternative would be to use built-in E4X.
