Sorry for my laziness on this. My hibernate.properties
hibernate.dialect = org.hibernate.dialect.MySQLDialect hibernate.connection.driver_class = com.mysql.jdbc.Driver ##hibernate.connection.url = jdbc:mysql://localhost/dhis2_pub?useUnicode=true&characterEncoding=UTF-8 hibernate.connection.url = jdbc:mysql://localhost/dhis204?useUnicode=true&characterEncoding=UTF-8 hibernate.connection.username = dhis hibernate.connection.password = dhis hibernate.hbm2ddl.auto = update By this you are right. I am using unix socket when setting with localhost on URL. I must write 127.0.0.1. I have changed and I am waiting to see it again. This happened not only with importing and etc... it happened on the login too.
