Hello.
I try to start using xwiki for us. We have installed xwiki on ubuntu 20.04.3
I read the xwiki docs and searched on google, but do not found solution for our problem.
The SOLR is not running and the only what i found in the catalina.out is the following line:
19-Jan-2022 11:42:12.890 WARNING [Thread-15] org.apache.catalina.loader.WebappClassLoaderBase.clearReferencesJdbc The web application [ROOT] registered the JDBC driver [org.apache.solr.handler.sql.CalciteSolrDriver] but failed to unregister it when the web application was stopped. To prevent a memory leak, the JDBC Driver has been forcibly unregistered.
Could somebody help to see why this happens and how to solve it?
Many thanks in advance.
Jörg
