Just updated from Hibernate 3.6 to Hibernate 4, now getting

10-Feb-2012 14:12:31 org.hibernate.dialect.DerbyDialect <init>
WARN: HHH000430: The DerbyDialect dialect has been deprecated; use one of the version-specific dialects instead
10-Feb-2012 14:12:31 org.hibernate.service.jdbc.connections.internal.ConnectionProviderInitiator c3p0ProviderPresent
WARN: HHH000022: c3p0 properties were encountered, but the org.hibernate.service.jdbc.connections.internal.C3P0ConnectionProvider provider class was not found on the classpath; these properties are going to be ignored.

I changed

config.setProperty("hibernate.dialect","org.hibernate.dialect.DerbyDialect");

to

config.setProperty("hibernate.dialect","org.hibernate.dialect.DerbyTenSevenDialect");

and I added

config.setProperty("org.hibernate.service.jdbc.connections.internal.ConnectionProviderInitiator","org.hibernate.service.jdbc.connections.internal.C3P0ConnectionProvider");


buts its made no difference

I use maven to configure my project, the relvent dependenices are

<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<version>4.0.1.Final</version>
<exclusions>

Hi,

to get the problem



solved, you must add hibernate-c3p0-<yourversion>.jar into your classpath.
You can find this jar in the distribution bundle under \lib\optional\c3p0\

For the Derby-Dialect I just have seen in the code that the warning


is given out, regardless if you use org.hibernate.dialect.DerbyTenSevenDialect or org.hibernate.dialect.DerbyDialect

so once you use org.hibernate.dialect.DerbyTenSevenDialect

you simply can ignore this warning message.

Thanks Im using Maven, but the problem was that I was using standalone c3po dependency

<dependency>
<groupId>c3p0</groupId>
<artifactId>c3p0</artifactId>
<version>0.9.1.2</version>
</dependency>

instead of the c3po package as a hibernate module:

<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-c3p0</artifactId>
<version>4.0.1.Final</version>
</dependency>

Do you think that it actuall uses the TenSeven dialect then or not, doesn't inspire confidence in Hibernate

Is this intended as a question or is it simply a statement?

Anyway I just opened
https://hibernate.onjira.com/browse/HHH-7059
in regard of this.

It was a question, the issue you raised answers my concerns, thankyou.
