Really simple question, how do I setup database connection pooling in JBoss? Is it installed by default?
I am currently using EJB3 to access a datasource defined through jboss. I am accessing the database through:
| <local-tx-datasource>
| <jndi-name>MyDS</jndi-name>
| <connection-url>jdbc:postgresql://localhost/mydb</connection-url>
| <driver-class>org.postgresql.Driver</driver-class>
| <user-name>username</user-name>
| <password></password>
| <min-pool-size>5</min-pool-size>
| <max-pool-size>20</max-pool-size>
| </local-tx-datasource>
|
| ...
|
| @PersistenceContext(unitName="myname")
| private EntityManager em;
| ...
| Object obj = em.find(MyClass.class, id)
|
All my code works correctly, I just want to understand how the database connections are pooled. Is there anything else I need to change in my EJB3 to take advantage of the connection pooling?
Thanks.
