Hi,

Thanks for the post, but I noticed this line of code
ContactEO contactEO = new ContactEO(contact); uses a constructor that was never defined in the ContactEO class. Is this intended??? If yes, then the code does not compile just like that.

Anyway, I got the same error as achref. I noticed that Vinay, said the mysql driver is not in the classpath, but in my case it is in my classpath. I’m not sure why it fails…basically same error as above. “Error creating bean with name ‘entityManagerFactory’ defined in class path resource ..”

Sorry @Dennis, Yes the ContactVO class and Contact interface were missing. I have added them right after the EO class. Also you can download the full code at the end of the tutorial.
Thanks for the correction.

Are you missing some packages & classes, like ContactVO?
