Oracle JDBC connection not working


Dear all, 

After uccessfull installation of Jasper Server ( 7.1.1. ) on Windows 2016 and installing jdbc drivers for Oracle (ojdbc6 or ojdbc8 ) I tried to create Data source. 

When testing the connection, system returns an error : 

'There was an error on the server. Try again or contact site administrators. (Error UID: 17451563-792e-42e2-b4c5-6db755ccd5e7)"

Oracle database is 11G XE

The same thing with the 7.2 version. 

Any ideas ? 

Thank you and Best Regards, 

Zoran Kuret

I have the same problem.

I have tried with drivers 6,7 y 8 JDBC.jar, but my database is 18XE.  
My tomcat is 9 and JasperServer 7. 

JRE and JDK:8

Checking the catalina log I have  found more details, because the jasper log just said that ERROR UID.
