I am running MySQL 5.1. First db ran just fine until I had to delete it and create a new one. It wouldn't connect anymore. On the command line, when I typed in "mysqld", it connected but if I typed in "mysql", I got the error message above. Within Eclipse, when I try to bring the server up, I got this trace: "...2010-03-05 16:23:02,289 INFO [org.springframework.orm.hibernate3.LocalSessionFactoryBean] - Building new Hibernate SessionFactory 609 [main] INFO org.hibernate.connection.ConnectionProviderFactory - Initializing connection provider: org.springframework.orm.hibernate3.LocalDataSourceConnectionProvider 2892 [main] WARN org.hibernate.util.JDBCExceptionReporter - SQL Error: 0, SQLState: 08S01 2892 [main] ERROR org.hibernate.util.JDBCExceptionReporter - Communications link failure The last packet sent successfully to the server was 0 milliseconds ago.
