The actual manual documentation state than the only required Tomcat dependencies are :
- Apache Geronimo
- Concurrency JSR-166
- aktivecortex-foo-commonj
- the database engine JDBC connector(s)
but, in the past for SPAGOBI, the 'commons-loggin' was described as a requirement too.
In fact:
- the 'commons-loggin' lib (and 'common-loggin-api') is still installed by the Knowage CE installer
- is is said to be a requirement in this other documentation
So is it still a requirement for the webapps, or is it just old stuff in the installer that is not needed anymore ?
PS: Tomcat 8 do not need anymore this library because he is now packaged with a fork of this library (JULI) to avoid the mixing of logs between Tomcat and webapps. My manual KnowageCE + Tomcat 8 install do not complain without it.
