Hi
I guess ReaderInterceptors are really for decorating the input and if
really needed blocking MBRs, but I don't think they are meant to replace
MBRs which is where you will deal with the actual reading.

Hi,
Thank you very much for your help.
I just wondering if I have to use JAXBContext in a ReaderInterceptor?
Can I use ReaderInterceptor for just I/O operation?
In the document, jsr339-jaxrs-2.0-final-spec, there is an example about
ReaderInterceptor (page 40):
@Provider
class GzipInterceptor implements ReaderInterceptor{
@Override
Object aroundReadFrom(ReaderInterceptorContext ctx) ... {
if (isGzipped(ctx)) {
InputStream old = ctx.getInputStream();
ctx.setInputStream(new GZIPInputStream(old));
try {
return ctx.proceed();
} finally {
ctx.setInputStream(old);
}
} else {
return ctx.proceed();
}
}
...
}
Can I use ReaderInterceptor like this example?
Could you please give me some advice?
Thank you very much!
Sincerely,
Di Ma

Hi
Please try the latest 2.7.7-SNAPSHOT, Dan did some related updates to
WS-A related code which might help resolving your issue
