[Gabriel Alejandro Soto Rivera]

Hello, good afternoon everyone.

I opened Jira issue TOMEE-4673
<https://issues.apache.org/jira/browse/TOMEE-4673> regarding the removal of
documentation referring to the Tomee webapp drop-in, as this was removed in
Jira issue TOMEE-3724 <https://issues.apache.org/jira/browse/TOMEE-3724>.
