Hello, it's been some time since I dabbled in hibernate. I wanted to create a basic hello world hibernate app and took all of the jars from hibernate core 3.3.2.GA and put them in my lib folder. My classpath correctly points to the jars. I have created a very simple MySQL db with one table with one int column (id, primary key) and one varchar(45) column (data). I have created a corresponding entity class with it's hbm.xml file in the same directory and a proper hibernate.cfg.xml.

Everything compiles, but when running I get the following exception:
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".

I have noted that in the hibernate-distribution 3.3.2 GA there is a jar file named slf4j-api-1.5.8.jar which was copied over into my lib dir along with all of the other jars. So I am puzzled as to why I am missing a jar. Do I need one of the other hibernate downloads besides the core?

Regards,

Tim

You need the SLF4J library. This get's me all the time too. You might also have versioning conflicts make sure that you have the correct version that hibernate needs. I don't know off the top of my head but if you post the versions you are using someone might be able to help you out.

SLF4J libraries can be found here if you can't find them in your hib dist folder anywhere

Ya, that was it. I needed the jar for slf4j. I was surprised that it wasn't included in the hibernate core distribution or that they at least failed to mention it was necessary to get.

Regards,

Tim
