Hi all,

I'm running my app with hibernate 3.0, in a non managed env, with c3p0. I'm besides configuring hibernate in my java code. While running my app i'm getting a UnsupportedOperation exception, saying me that i should give a JDBC connection. while my driver is in the classpath. to see where's the error i'm just quering a simple "from obj".

Do you have any idea of the reason of this problem?
thank you

Mapping documents: the problem is before the mapping

Name and version of the database you are using: mysql, 4-1

The generated SQL (show_sql=true):no sql is generated, i cannot get the jdbc :)

i cannot understand if it's an automessage or not!
I repeat, the tutorial doesn't seems to help, i've getting this exception while everything is where should be.

thanks

No, you haven't configured Hibernate for a database connection. Please follow the tutorial step-by-step.

this is the configuration:

cfg.setProperty("connection.url", "jdbc:mysql://localhost/test);
cfg.setProperty("hibernate.dialect", "org.hibernate.dialect.MySQLDialect");
cfg.setProperty("connection.driver_class", "com.mysql.jdbc.Driver");
cfg.setProperty("connection.username", "root");
cfg.setProperty("connection.password", "pass");
cfg.setProperty("show_sql", "true");
cfg.setProperty("c3p0.min_size", "1");
cfg.setProperty("c3p0.max_size", "20");
cfg.setProperty("c3p0.timeout", "300");
cfg.setProperty("c3p0.max_statements", "50");
cfg.setProperty("c3p0.idle_test_period", "3000");
cfg.addClass ....


what's wrong?
I need to configure in the app's code, and not in a file

Thank you christian

solved thanks

I'm sorry Christian,
but nothing has been solved, i reask you, nothing seems to me to be wrong, i'm following the hibernate in action chapter about how to configure the whole, but it does always require me the jdbc connection.

I don't know where to look,

thanks for further help for my dumb question

The configuration property names are hibernate.* not a mix of random names you copied from somewhere.

Thank you christian.
