I did use printstacktrace but it is not giving any exceptions.

what i cant understand is why is it happening only when i deploy my

[appengine-java] Re: Or filters cannot be applied to multiple properties
Hi John, I quickly skimmed over the twig project, it seems that it works directly on top of the datastore.

[appengine-java] Re: How long is my application state hold on the app engine?
I can also add that a new deployment does not clear memcache (it was an issue for me since it was hiding all changes in my upload). Memcache on the other hand can expire in any moment, so you must be ready to accept some data loss if you don't want to back it using the dataastore.

Re: [appengine-java] Re: Or filters cannot be applied to multiple properties
Yes, it is a replacement for Datanucleus designed specifically for the datastore. There are also other alternative frameworks such as Slim3, Objectify and SimpleDS all with their own unique features. Twig is the only one to support these merged OR queries you asked about. One more point - Twig executes the two branches of the OR query in *parallel* and then merges the results. It can do this because it has support for async (non-blocking) datastore operations. this means that even if you have hundreds of branches to your query they should return in roughly the same amount of time.

*Are* there any serious RPC alternatives right now? Sounds like
gwt-syncproxy isn't quite ready for prime time (and makes me nervous
since it's not using a published protocol), the *-WS stuff is a
trainwreck, and *-RS is not really convenient as an RPC layer. I

I think you did yourself a disservice by wrapping these two issues

The first issue looks like you're not detaching your entities before
serializing them. This is a JDO issue. I suggest dropping JDO and
using something simpler like Objectify ;-)
The issue with exceptions looks more serious. This is something that
will need to be fixed in Hessian (or your custom serializer). If you
cut down your issue to just this, you might get better results from
Caucho.

Hi Jeff. I was hoping to hear from You since I saw that You solved
some GAE issues on the hessian-interest list. I already posted the
issue on the hessian-interest list here:

I also posted several forum questions:
http://forum.caucho.com/showthread.php?t=

And a few bug reports:
http://bugs.caucho.com/view.php?id=4061
http://code.google.com/p/googleappengine/issues/detail?id=3305
The posts actually describe two issues one with arraylist
serialization and the other with exception serialization. The posts
also include test projects with code that reproduces the issues. I
also managed to solve the issue today by using a custom serializer.
Here is how. First the Serializer:
public class ThrowableSerializer extends AbstractSerializer {
�...@override
public void writeObject(Object obj, AbstractHessianOutput out)
throws IOException {
if (obj != null) {
final Class cl = obj.getClass();
if (out.addRef(obj))
return;
int ref = out.writeObjectBegin(cl.getName());
Throwable tr = (Throwable) obj;
ByteArrayOutputStream bos = new ByteArrayOutputStream();
ObjectOutputStream oos = new ObjectOutputStream(bos);
try {
oos.writeObject(tr);
if (ref -1) {
out.writeString(value);
out.writeBytes(bos.toByteArray());
out.writeMapEnd();
} else {
if (ref == -1) {
out.writeInt(1);
out.writeString(value);
out.writeObjectBegin(cl.getName());
}
out.writeBytes(bos.toByteArray());
}
} finally {
oos.close();
bos.close();
}
} else
out.writeNull();
}
}
The other class we need is the Deserializer:
public class ThrowableDeserializer extends AbstractDeserializer {
//private static final Logger l =
Logger.getLogger(ThrowableDeserializer.class.getName());
�...@override
public Class getType() {
return Throwable.class;
}
�...@override
public Object readMap(AbstractHessianInput in) throws IOException
{
int ref = in.addRef(null);
byte[] initValue = null;
while (!in.isEnd()) {

[appengine-java] Re: Eclipse Plugin and Proxy Server
In Eclipse, goto WindowPerferenceGeneralNetwork Connection, set up the proxy host name and port there. But for Netbeans, although I set up similarly, I still have connection timeout when I deploy. I don't know if the proxy setup is incorrect or the google credential is incorrect. So I need help too.

[appengine-java] Dance Dance Robot error / Channel API
Hello there,
I am building a GWT+ GAE app based on Dance Dance Robot app, the demo
Google IO demo app showcased at Google IO.
I am using the Channel API (Java AppEngine 1.3.5) . I am almost there
but there is one hick up on the GWT client side (Java):
When running the app I get an error:
==
- Uncaught exception escaped.
com.google.core.client.JavaScriptException: (TypeError): $wnd.goog is
undefined.
==
This comes from the ChannelFactory.java on the client side. Here it
is:
public class ChannelFactory {
public static final native Channel createChannel(String
channelId) /*-{
return new $wnd.goog.appengine.Channel(channelId);
}-*/;
}
Again this is straight from the Dance Dance Robot demo app.
I am pretty sure it is a stupid mistake on my part but can't find it.
Any suggestion would be greatly appreciated.
Daniel
