Hi,
thanks for the reply !!I made the changes to the page you posted to me twice but the result was always the same.Then I found this procedure:
https://ingmmurillo-dwh-bi.blogspot.com/2015/10/configuracion-de-pentaho-bi-server-v54.html
and now, I have some errors in the log file, but pentaho starts and seems to work.
Not having the necessary skills, I can't compare the two procedures and figure out which part generates the error I wrote in the forum !!!
Best Regards
