Once configured correctly, I would like to reference the new C3P0PooledDataSource in my Java WAR through its JNDI name. As I am using Spring it would be something similar to: [src/webapp/WEB-INF/applicationContext.xml] *<jee:jndi-lookup id="dataSource" jndi-name="java:PooledDS" />* However, I don´t know how to configure this library properly. I tried to place *c3p0-0.9.2.1.jar* and *c3p0-service.xml* in the folders commented in the manual but I had no luck :( . So: * *Is it possible to use c3p0 connection pool inside JBOSS AS 7.1.1? How should I configure it?* I started to "play" with c3p0 because of its large number of configuration properties, but I don´t know if c3p0 is better than embedded JBOSS pooling capabilities. * *Does c3p0 library deserve to be used instead of JBOSS embedded connection pool (i.e. configuring the datasource with the admin console/web) ?*         I am currently developing a project which uses a MySql database. I appreciate any comments to these matters.* * -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/825446#825446] Start a new discussion in Datasource Configuration at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
