Line 76 of Shell.java, explains that the functions "print", "quit",
"version", "load", "help" are not part of ECMA.
So, you'll have to define them in your source file.
*What i do:*
Step 1: Define the print function in MyClass (as in Shell.java)
Step 2:
Approach 1: Using the rhino engine in Java
ScriptEngineManager manager = new ScriptEngineManager();
ScriptEngine engine = manager.getEngineByName("js");
try {
engine.eval(new FileReader(new File("test.js")));
} catch (ScriptException e1) {
e1.printStackTrace();
} catch (FileNotFoundException e) {
e.printStackTrace();
}
Approach 2: Using rhino form your own jar/source
Context cx = Context.enter();
ScriptableObject scope = cx.initStandardObjects();
String[] names = { "print"};
scope.defineFunctionProperties(names, RunJS1.class,
ScriptableObject.DONTENUM);
try {
cx.evaluateReader(scope, new FileReader("test.js"), "test.js",
0, null);
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
Any other suggestions/comments?
Cheers,
Shauvik
