Hi!

I want to use the wrapAsJavaObject()-method to make my Java classes 
available in the rhino scripting runtime.

My code looks like this:

Scriptable wrappedByteString = 
scriptContext.getWrapFactory().wrapAsJavaObject(scriptContext,
                                                            app,  <-- 
this is the application scope
                                                            new 
ByteString(),
                                                            
ByteString.class);

How can i make this new class available for the script application, e.g. 
that someone can use something like 'var f = new ByteString()'?

Formerly i used the the "defineClass()" method to register this class in 
the application context. But that was quite boring...
Is there something similar i have to do?

If i try to create a new object in my script i get the following exception:

org.mozilla.javascript.EvaluatorException: Constructor for "ByteString" 
not found.

org.mozilla.javascript.DefaultErrorReporter.runtimeError(DefaultErrorReporter.java:64)
    at org.mozilla.javascript.Context.reportRuntimeError(Context.java:815)
    at org.mozilla.javascript.Context.reportRuntimeError(Context.java:870)
    at org.mozilla.javascript.Context.reportRuntimeError1(Context.java:834)
    at 
org.mozilla.javascript.ScriptRuntime.getExistingCtor(ScriptRuntime.java:927)
    at org.mozilla.javascript.Context.newObject(Context.java:1360)

But the construcor is in the class and public.

Do you have some example source codes? Am i missing something?

Thanks for your support.

Kind regards,

Frank
