Sir,

I have tried making the jpa application which you have given on this site . But then also I m facing problem in that like : If i make then also it is giving error.

If I try to run the application provided by you then also. it is giving me error of library missing and after importing the libraries it is then giving this error message:::::

Compiling 1 source file to C:\Users\WAHEGURU\Downloads\Compressed\netbeansjpaexamples_2\JPACRUD\build\classes compile-single: run-single: log4j:WARN No appenders could be found for logger (org.hibernate.cfg.annotations.Version). log4j:WARN Please initialize the log4j system properly. org.hibernate.exception.JDBCConnectionException: Cannot open connection BUILD SUCCESSFUL (total time: 1 second)

help me in this and kindly if you can do all that in detail which you have given in your tutorial then plz do so. because without making an entity class it is not possible to run the application.
