Raj,
I am working on integrating your changes into the current CVS code, but I
have had some problems while testing. I am using Xalan 2.3.1. I am finding
that, at least for small payloads, using the SAXSource -> DOMResult
transform takes longer than using the DOM Parser. I am also getting a SOAP
fault on the client when running the addressbook sample.
What parser/transformer were you using? Were you testing with small or
large payloads?
