Hi,

When I initialize my application with Hibernate and c3p0, a ClassCastException is thrown. See the stacktrace below. This seems like an exception not related to my code. Is is something in my settings, or am I missing something.

Yhank you and have a great day.

Hibernate version: 3.0.3

c3p0 version: 0.9.0.2

Name and version of the database you are using: MySQL 4.1.7-nt

Hibernate config:
<hibernate-configuration>
<hibernate.connection.driver_class>com.mysql.jdbc.Driver</hibernate.connection.driver_class>
<hibernate.connection.url>jdbc:mysql://localhost/jsportal_0000001?autoreconnect=true</hibernate.connection.url>
<hibernate.connection.username>root</hibernate.connection.username>
<hibernate.connection.password>****</hibernate.connection.password>
<hibernate.dialect>org.hibernate.dialect.MySQLInnoDBDialect</hibernate.dialect>
<hibernate.c3p0.min_size>1</hibernate.c3p0.min_size>
<hibernate.c3p0.max_size>5</hibernate.c3p0.max_size>
<hibernate.c3p0.timeout>120</hibernate.c3p0.timeout>
<hibernate.c3p0.max_statements>50</hibernate.c3p0.max_statements>
<hibernate.c3p0.idle_test_period>300</hibernate.c3p0.idle_test_period>
</hibernate-configuration>
