Java Hibernate and XML not working

Question

I have this project in which I have to use hibernate, this is the first time I use, I don't really know many things about it and I get a bunch of exceptions when I run my program. I have installed the required libraries from hibernate in eclipse. But when I run I get this. I'm sorry that I paste all the errors here but I really have no idea how I could fix them and where to start. Could you please help me

Answer 1

Your Exception shows below lines

Exception in thread "AWT-EventQueue-0" org.hibernate.service.classloading.spi.ClassLoadingException: Specified JDBC Driver com.mysql.jdbc.Driver class not found

That means your jdbc driver is not added in library or properly configured.

Please check your config file

You're missing the Mysql Connection JAR on your classpath.

This jar contains the driver: com.mysql.jdbc.Driver

Download it and add,problem will be solved

you can download mysql java driver from http://www.mysql.com/downloads/connector/j/

Answer 2

You are missing mysql-connector jar .. Kindly download appropriate version and put it in your project class path.. this will solve your problem...

Answer 3

Specified JDBC Driver com.mysql.jdbc.Driver class not found

Include it in you classpath.

Answer 4

You are missing mysql-connector jar in your classpath and hence the exception.
