You can find org.apache.tomcat.dbcp.dbcp.BasicDataSource in common/lib/naming-factory-dbcp.jar. If you put commons-dbcp.jar, commons-pool.jar and commons-collections.jar in common/lib you (maybe) should be able to use org.apache.commons.dbcp.BasicDataSource. I do it in a similar way - I have my own ressource factory, which extends org.apache.commons.dbcp.BasicDataSourceFactory and it works in tomcat 5.5 with the above jars.

Mai 2005 18:47 An: Tomcat Users List Betreff: Re: DBCP ClassCastException I'm using BasicDataSource because javax.sql.DataSource does not have methods to set the driver class name, url, username/pwd etc. My app needs to support different databases and the driver is loaded based on which database is installed. If I use org.apache.tomcat.dbcp.dbcp.BasicDataSource, then my code is not portable to JBoss/Weblogic etc right? BTW, which jar is org.apache.tomcat.dbcp.dbcp.BasicDataSource in? Thanks for your response.
