In my web application (a Servlet) I create and use an EntityManagerFactory and then shut it down with the close() method in my servlet destroy() method. However, when I shut down my web application MySQL admin console shows me that there is still an open connection to the database. I can see the hibernate log statement saying it has closed, but the connection remains.

I'm using Tomcat and have my DataSource configured in a context.xml file like this;

<Context>
<Resource name="jdbc/myDataSource"
auth="Container"
type="javax.sql.DataSource"
maxActive="20"
maxIdle="10"
maxWait="3000"
username="testuser"
password="xxxxx"
driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost:3306/myschema"
defaultAutoCommit="false"/>
</Context>

Any suggestions as to why the connection isn't being closed?
