I'm having a problem with enabling c3po connection pooling with hibernate. I'm using hibernate 3.2.1.sp1 and c3po-0.9.1.jar. My context is a junit 3.8.1 test suite running inside of MyEclipse 5.1 w/ jdk 1.5. My db is oracle 8.1.
My junit test works fine.
Until I attempt to specify a simple c3po connection pool inside my hibernate.cfg.xml file. If I add that, I get the following exception:
Code:

I have no idea why I'm getting an exception on a jboss/jmx PropertyAccess class not found. I'm not using boss at all. I tried to add the jboss-jmx.jar file to my classpath, but that did not fix the problem either.
Any ideas?
Here's my config file:
Code:
<hibernate-configuration>
<session-factory>
<property name="hibernate.connection.username">cprs2</property>
<property name="hibernate.connection.url"> jdbc:oracle:thin:@smaug:1521:cprs2 </property>
<property name="hibernate.dialect"> org.hibernate.dialect.OracleDialect </property>
<property name="hibernate.connection.password">****</property>
<property name="hibernate.connection.driver_class"> oracle.jdbc.driver.OracleDriver </property>
<!-- configuration pool via c3p0 -->
<property name="hibernate.c3p0.min_size">10</property>
<property name="hibernate.c3p0.max_size">100</property>
<property name="hibernate.c3p0.max_statements">0</property>
<property name="hibernate.c3p0.timeout">100</property>
<property name="hibernate.c3p0.idle_test_period">100</property>
<!-- hibernate mapping files -->
<mapping resource="com/org/hibernate/Courtplan.hbm.xml" />
</session-factory>
</hibernate-configuration>
