Hibernate Error in JDeveloper

Question

Hi,
I am developing a Hibernate based application, and I have been going thru some sample application to understand how to go about it.
While running one of the sample applications, I get the following error. I have tried placing the slf4j-api-1.5.2.jar in the classpath,
in the jdeveloper lib path. But I keep getting the following error.
Please let me know if there is any additional step required to configure and deploy Hibernate in Jdeveloper.
I am using JDeveloper 10.1.3.4

Answer 1

I was able to figure out the reason for this error.
The jar file slf4j-api-1.5.2.jar supplied with the hibernate download does not contain all the class files. On using the jar file downloaded from the website, [http://www.slf4j.org/download.html|http://www.slf4j.org/download.html] ,
I am able to run the sample hibernate example without any error.
Hope this helps anybody who faces a similar error.
