Hey all, I tried posting this on the appengine group a while back, but no success.
For reference, it's here: (http://groups.google.com/group/google- appengine-java/browse_thread/thread/2124e4ffdbe79ff7/ca50fbb0408ba87f? lnk=gst&q=java.io.SerializablePermission#ca50fbb0408ba87f) Long story short, doing the following breaks in appengine: Scriptable obj = ... ByteArrayOutputStream bs = new ByteArrayOutputStream(); ScriptableOutputStream out = new ScriptableOutputStream(bs, scope); // breaks here! out.writeObject(obj); Blob blobToSave = new Blob(bs.toByteArray()); // do something with blob bs.close(); out.close(); The reason is because in appengine, there is a missing security permission that the Rhino Serializer is trying to use: Uncaught exception from servlet java.security.AccessControlException: access denied (java.io.SerializablePermission enableSubstitution) at java.security.AccessControlContext.checkPermission(Unknown Source) at java.security.AccessController.checkPermission(Unknown Source) at java.lang.SecurityManager.checkPermission(Unknown Source) at java.io.ObjectOutputStream.enableReplaceObject(Unknown Source) at org.mozilla.javascript.serialize.ScriptableOutputStream.<init> (ScriptableOutputStream.java:84) Does anyone know how I can use the serializer in appengine? I have implemented a utility class that converts between Scriptable and JSON string representation, but it is admittedly not as robust as the serializer and I really don't want to reinvent the wheel here. I greatly appreciate your help! _______________________________________________ dev-tech-js-engine-rhino mailing list [email protected] https://lists.mozilla.org/listinfo/dev-tech-js-engine-rhino
