I am using JBOSS 5.1.0.GA, MySQL 5.5 and Hibernate 3.3.1 GA (included with JBOSS) + Spring.
My question is do I need to add c3p0 as a data source in my spring/hibernate configuration for
connection pooling or are the setting in the JBOSS mysql-ds.xml setting enough.
My mysql-ds.xml is the following:
<datasources>
<local-tx-datasource>
<jndi-name>MySqlDS</jndi-name>
<connection-url>jdbc:mysql://localhost:3306/ecotrak</connection-url>
<driver-class>com.mysql.jdbc.Driver</driver-class>
<user-name>ecotrak</user-name>
<password>ecotrak</password>
<min-pool-size>5</min-pool-size>
<max-pool-size>20</max-pool-size>
<idle-timeout-minutes>5</idle-timeout-minutes>
<exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.MySQLExceptionSorter</exception-sorter-class-name>
<!-- should only be used on drivers after 3.22.1 with "ping" support -->
<valid-connection-checker-class-name>org.jboss.resource.adapter.jdbc.vendor.MySQLValidConnectionChecker</valid-connection-checker-class-name>
<!-- sql to call when
connection is created
<new-connection-sql>some arbitrary sql</new-connection-sql>
-->
<!-- sql to call on an existing pooled
connection when it is obtained from pool - MySQLValidConnectionChecker is preferred for newer drivers
<check-valid-connection-sql>some arbitrary sql</check-valid-connection-sql>
-->
<!-- corresponding type-mapping in the standardjbosscmp-jdbc.xml (optional) -->
<metadata>
<type-mapping>mySQL</type-mapping>
</metadata>
</local-tx-datasource>
</datasources>
