Need help on this.

Sending HTTP2 request to Apple push server using OKhttp3 client.

Server: Webshere 9 Java : 8 OKhttp3 :4.8.1 Also added ALPN jar in boot classpath. ALPN jar version mapped accurately with JDK version in bootclasspath.

Getting this error message in IBM Webshere 9 log file. ALPN callback dropped: HTTP/2 is disabled. Is alpn-boot on the boot class path?

Thank you for help.

If you can upgrade past Java 8u252 then you won't need alpn-boot on the bootclasspath

I suggest looking at whether this is possible first.
