RE: Regarding Compilation Steps for Tomcat version 9 on RHEL8

[Vivek Naruka (EXT-NSB)]

Hi,

Please find attachment of Image. During study on changelog.txt we could see 
support of OpenSSL 3.0. for tomcat native.

Please do let us know if Tomcat can provide extended support of OpenSSL1.1.1  
beyond the EOL(End of life cycle) i.e after September 2023?

Vivek Singh

Tomcat 9.0.x does not require OpenSSL to compile. What makes you think it does?

Try looking in the BUILDING.txt file in the root of the source tarball.

The build should be fully reproducible, providing you follow the additional 
instructions for reproducible builds.


Getting back to the OpenSSL 3.0 question.

Tomcat Native, which does have a dependency on OpenSSL, is compatible 
with OpenSSL in both the 1.2.x and 2.0.x branches. What makes you think 
that it is not?

You can use Tomcat Native 1.2.x or 2.0.x with Tomcat 9.0.x but if you 
use Tomcat Native 2.0.x, you can't use the APR/native connectors - you 
must use NIO or NIO2.

Receiving HTTP (any version but 3 prefered) over UDP

[Aryeh Friedman]

I just tried the following command to test if tomcat does in fact listen on UDP:

aryeh@sarek1024% nc -u localhost 8080
GET / HTTP/1.1


aryeh@sarek1024%

Which is nice to see tomcat is listening but it is not apparently
processing any requests since doing the same on TCP yields:

aryeh@sarek1024% nc localhost 8080
GET / HTTP/1.1
HTTP/1.1 400
