REST CDATA Marshalling
I'm attempting to get String data wrapped in CDATA before being
returned to the client. I do not want special characters to be
escaped. First I tried simply wrapping the properties in my getters
with the CDATA block. Unfortunately, JAXB continued to escape all the
special characters.
I found this post:
http://forum.java.sun.com/thread.jspa?threadID=607524&messageID=3531931.
Although promising, I could not find out how to setup JAXB in my
applicationContext in such a way to set this as the XMLSerializer.
Has anyone accomplished this? It seems as though it would be a fairly
common need.
Thanks,
T

Hi,
One way would be to use a CXF JAX-RS implementation. I'm presuming no SOAP is involved as Todd is
asking about CDATA in a context of the REST application, right ?
If so, then with JAX-RS one can just return a String which uses CData to encapsulate XML..., with no JAXB involved.
JAXB might be used to create the actual XML, but the String will be written directly to the output stream or read as is from the input stream...
Cheers, Sergey

Yea, there really is NOT a way to do this with JAXB. Jaxb doesn't call
the writeCData method on the XmlStreamWriter at all, ever. (I just
grepped the source). The ONLY way I can see to do this would be write
a XmlStreamWriter wrapper that wraps the "real" writer and keeps track
of the element it's in and if in the appropriate element, foward the
writeCharacters calls to writeCData calls instead. Not sure how worth
it that would be.

Indeed, the CXF JAXB data binding does not provide any simple way around
this.
In the example at hand, the code knows the target byte stream for the
output, and is concocting a specialized XML writer that has the desired
behavior. CXF uses StaX to write out XML. You'd need a StaX implementation.
I wonder if you could create an interceptor that rewrote the XML the way you
like it? I'm not much of an interceptor expert.

Why do you want to do this? The distinction between CDATA and various
&-entities is way below the level of web service semantics. Any conformant
XML parser is going to treat them identically.
