Recently we faced an issue while upgrading to the latest version 5.0.1 for poi.
And we ended up having following jars for logging all logs to log4j
- log4j-slf4j-impl-2.14.0.jar
- jcl-over-slf4j-1.7.30.jar
- slf4j-api-1.7.30.jar
- log4j-api-2.14.0.jar
- log4j-core-2.14.0.jar
- log4j-web-2.14.0.jar
We use hibernate in our web application. And hibernate needs slf4j for logging.
With our update the hibernate logs are no more logged. If anyone has same issues do let me know in comments.
