I tried that with standalone Tomcat and it works. I can deploy Jersey-1 and
Jersey-2 apps together.
I was wondering whether Loader with delegate=false work in context for
embedded?
Thanks

Thanks for a very quick reply Mark.
The Tomcat version is 8.5.46.
Though I do plan to upgrade to 9.0.36 in the coming weeks.

Hi,
Due to some backward compatibility concerns, I need to support both
Jersey-1 and Jersey-2 on the same Tomcat instance. This is an embedded
tomcat which runs inside a JVM application.
Since, Jersey-1 and Jersey-2 have different JAXRS versions, I tried to
remove both jsr311 and javax.ws.rs-2 f

Hi,
We are observing that under high load, my clients start receiving a GoAway
frame with error:
*Connection[{id}], Stream[{id}] an error occurred during processing that
was fatal to the connection.*
Background : We have implemented our clients to close connections after

Hi,
I am trying to move to HTTP2 based APR connector from my HTTP1 based

I am trying to form some sort of throughput benchmark for HTTP2 in

Hi,
For this particular cipher, the server sends a RST to the client after the
certificate exchange is done. And the handshaking fails,for the first time
only. Second request onwards handshaking happens and the traffic flows as usual.
What I understand is,I can provide a set of ciphers to the c
cypher suite? Or any
other way that I can resolve this issue.
Thanks a lot.

Chris,
With c=1 it is 70k req/sec and with c=2 it is 35k in both i.e the total req/sec
