Hi Piotr,
Ok, I will give it a try. I will post now a new thread with a new matter to not
mix.
Thanks,
Joan.

I was afraid that might happen. A small breaking change between Log4j Core 2
and 3 broke both artifacts.
I have freshly compiled a new `3.0.0-SNAPSHOT` version of `log4j-jakarta-web`,
which should work. You just need to add our snapshot releases repo:
<repositories>
<repository>
<releases>
<enabled>false</enabled>
</releases>
<id>apache.snapshots</id>
<name>Apache Snapshot Repository</name>
<url>https://repository.apache.org/snapshots</url>
</repository>
</repositories>
The release process for a beta release is not long, but we have a documentation
backlog that we need to address before performing a release, so it might take
some time before we publish a `beta1`.
On the other hand the code of the Jakarta artifacts is pretty stable and has
not changed in years. It should be safe to use it in a test environment.
