Linux Mandriva: Tomcat can not get MySQL database connection, why? - mysql

Question

I installed Tomcat 7 and MySQL database on Linux Mandriva, but the application is deployed in the container can not get a connection.
I wrote two simple tests, and when to run them from the client, I get the connection -
public class TestHibernate {
/**
* #param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
User user = new User();
user.setName("userName");
user.setPassword("userPassword");
Session session = HibernateUtil.
getSessionFactory().openSession();
session.beginTransaction();
session.save(user);
session.getTransaction().commit();
session.close();
}
}
Part of HibernateUtil -
...
cnf.setProperty("hibernate.connection.url", "jdbc:mysql://ip:3306/gibrid");
cnf.setProperty("hibernate.connection.username", "java");
cnf.setProperty("hibernate.connection.password", "java");
...
Jdbc test -
public class TestJdbc {
public static void main(String[] args) {
Connection conn = null;
String url = "jdbc:mysql://ip:3306/";
String dbName = "gibrid";
String driver = "com.mysql.jdbc.Driver";
String userName = "java";
String password = "java";
try {
Class.forName(driver).newInstance();
conn = DriverManager.getConnection(url+dbName,userName,password);
System.out.println("Connected to the database");
conn.close();
System.out.println("Disconnected from database");
} catch (Exception e) {
e.printStackTrace();
}
}
}
In these cases, I get a connection and can work with the database. But when I request from the client browser, I get a timeout. Why is that?
I would be very grateful for the information.
Here is the catalina.out -

Answer 1

I'm not familiar with Hibernate, so I don't know if this is relevant:
"hibernate.properties not found"
"using driver: com.mysql.jdbc.Driver at URL: jdbc:mysql://---ip here----/gibrid"
Is the IP and port the same as in your test programs?
This blog hints at configuration problems with C3PO. One comment hints at different timeout settings between Mysql and C3PO. HTH

Answer 2

Editing your mysql configuration file to bind on 0.0.0.0 or your ip instead of 127.0.0.1 might work.
