java.lang.ClassNotFoundException: org.apache.log4j.Level

Question

I\'m trying to use hibernate 3.5.1 final in a swing application and here are the jars I\'m using:

• hibernate-core-3.5.1-Final

Answer 1

You need to download log4j and add in your classpath.

Answer 2

You also need to include the Log4J JAR file in the classpath.

Note that slf4j-log4j12-1.6.4.jar is only an adapter to make it possible to use Log4J via the SLF4J API. It does not contain the actual implementation of Log4J.

Answer 3

In my environment, I just added the two files to class path. And is work fine.

slf4j-jdk14-1.7.25.jar
slf4j-api-1.7.25.jar
