Examples of javax.script.ScriptEngineManager

javax.script.ScriptEngineManager
This class is copied from the Livetribe 2.0.6 source with one important extension: The Livetribe implementation has the {@link #setGlobalScope(Bindings)} and {@link #getGlobalScope()} methods,which the Sun implementation of this class has {@link #setBindings(Bindings)}and {@link #getBindings()} methods.
Another change is to not scan the class loader initially when creating the ScriptEngineManager -- the assumption is that the ScriptEngine registrations are managed inside the framework.

            if (script != null) {
                return executeScript(script, functionName, scriptContext, args);
            }
        }
        String fileExtension = getFileExtension(filePath);
        ScriptEngineManager manager = new ScriptEngineManager();
        ScriptEngine engine = manager.getEngineByExtension(fileExtension);
        if (engine == null) {
            throw new IllegalArgumentException("The script type is not supported for location: " + filePath);
        }
        if (Debug.verboseOn()) {
            Debug.logVerbose("Begin processing script [" + filePath + "] using engine " + engine.getClass().getName(), module);
