Hi all,
I'm just testing out Rhino a little and came across an issue. I made
the following ScriptedObject - absolutely useless, again, just for
testing -:
public class MSRScreen extends ScriptableObject {
private static final long serialVersionUID =
-6246695110439492400L;
public MSRScreen() {}
public MSRScreen(string name) {
jsFunction_flush();
}
public void jsConstructor() {}
public void jsFunction_flush() {
//Do absolutely nothing
}
}
I have the following piece of code to run a script:
private static Context context;
private static ScriptableObject scope;
public static void run(String script)
{
try {
context = Context.enter();
scope = context.initStandardObjects(null, true);
ScriptableObject.defineClass(scope, MSRScreen.class);
scope.defineFunctionProperties(new String[] { "screen",
"print" }, MSRhino.class, ScriptableObject.DONTENUM);
context.evaluateString(scope, script, "Test", 0, null);
}
catch(Exception ex) {
ex.printStackTrace();
}
finally {
Context.exit();
}
}
public static Object screen(String name) {
return Context.toObject(new MSRScreen(name), scope);
}
public static void print(String value) {
System.out.println(value);
}
I pass to following small JavaScript to the run-method:
var a = screen("LCD");
a.flush();
For some reason, "var a" becomes a java.lang.String and the second
line will then complain it can't find "flush" in java.lang.String.
Same occurs when i do directly screen("LCD").flush();
Why is this? Am I missing a specific piece of code? Please note that
I'm not interested in Live Connect or alike, my test in this case is
instancing a Java-object which has JS-methods in it and pass it to JS
to be used as that. Doing a direct "new MSRScreen().flush" from within
JS works fine, so it's not the class. For some reason, Rhino "forgets"
that the object is a MSRScreen and turns it into a String (at least,
thats what I see happening).
Any help is much appreciated!
Yours sincerely,
Lennard Fonteijn
