Hi,
I am new to this forum . I have implemented small application i.e for retrieving data from the database and displaying data on the console. For this I have implemented one JSF file it containing one button whenever I click on the button it is going to call the controller but the problem is whenever I am clicking on button my controller was calling but it is giving an error i.e.
org.hibernate.exception.GenericJDBCException: Cannot open connection
can any one tell me how to resolve this problem?
