I need some help here. I'm trying to use hibernate with mysql using the tutorial from hibernate source code ( that using hsqldb ). I've change the hibernate.cfg.xml to mysql and when I run it with ant, it shows error likethis :
[java] java.sql.SQLException: Cannot connect to MySQL server on localhost:3306. Is there a MySQL server running on the machine/port you are trying to connect to? (java.lang.NumberFormatException)
There is no way that my Mysql Server is not running because I check it with Mysql Client tools and it connected normally. And I already placed the mysql connector/j jar in /lib directory. I don't know what's wrong with it. Can somebody help me ?
i'm using hibernate 3.1.3, mysql 5.0.22, mysql-connector-java-3.1.13, mysql-connector-java-3.1.13
I got the same exception & resolved the issue after 3 hectic days.Check if you are using I hibernate3. In this version it is req to explicitly mention the connection class name. Also check if the jar is in classpath. Check steps & comments in below link
