Re: [jetty-users] Problem reading POST body with embedded Jetty 12.0.x
|
Hi Greg,
Thanks. The particular parts of the application are maintenance
oriented and not particularly performance critical but I would love
to learn more about this.
For now, my priority lies with getting our application running on
Jetty 12. I was expecting to have to do quite some modifications to
the application code since we use Jetty in embedded mode. Actually
it was a lot easier than I expected and this issue is the last thing
that keeps us from moving to Jetty 12. Not bad so far but I would be
very happy to get this out of the way.
If you have any suggestions as to what I could do to shed more light
on the issue please let me know.
Cheers,
Silvio

Silvio,
Let's get your existing code working.... but then I'd
really like to show you how you can use jetty-12 handlers to
do that expansion for you prior to any buffering and/or
blocking input streams.

Please open an issue with the code example, where it throws,
and the
stack trace.
GH issues are better for this kind of analysis.
Thanks!
