Scott,

The code is here:

https://github.com/fl4via/undertow/tree/JAKARTA_EE_9

You just need to fetch that branch and follow the steps:

- fetch Batavia project that is used to transform bytes and build it: https://github.com/wildfly-extras/batavia

- build Undertow with maven clean install -DskipTests (or do not skip them, but keep in mind they take quite a long time to run)

- then use the generated artifacts as dependencies wherever needed:

  undertow-servlet-jakartaee9

  undertow-websockets-jsr-jakartaee9

  Since these artifacts are untested, probably you will come back to me with feedback if you find any trouble using them. :-)

  Feel free to ping me at any time.

As soon as this passes, I'll deploy those artifacts to Nexus.

Regards,

Flavia
