Hi, according to an older post from Daniel, it should be possible to implement full streaming by implementing the interface "Provider<StaxSource>".
I got a small sample service up and running and CXF is dispatching the call into my "invoke" method. With this service I would like to return a very large response which is the result of a JDBC query. However, I am a little bit lost in the XML APIs. I have to return an instance of "StaxSource" to CXF. "StaxSource" requires an instance of "XMLStreamReader" in its constructor, and "XMLStreamReader" is a very, very low level XML (pull) API. Is it somehow possible to make "XMLStreamReader" work with objects? Is there some kind of "bridge" that I can insert between my objects and "XMLStreamReader", to have a little bit more comfort? My object graph is very simple: Object "A" contains (aggregation) some tiny "B"s. So it would be no problem to construct one "A" in memory and insert all the nested "B"s in memory. Then I would like to give this "A" to CXF/XMLStreamReader for serialization and I would construct the next "A" in memory. Unfortunately, I cannot find such a "bridge". I took a look at XStream. With its "xstream.createObjectOutputStream()" and "objectOutputStream.writeObject(a)" I would have the above semantics of constructing one "A" in memory and serializing one "A" after another. But I did not find any possibility to put XStream and XMLStreamReader together. Do you have any hints for me? Are there any other solutions to stream small chunks of the result to the client - chunk by chunk? Without using this low level XMLStreamReader? Regards, Martin
