This issue has been asked and answered again and again in the mailing list of tomcat, struts, and commons. Consider that Oracle is so populate, setup should be pretty straightforward.
My advice is to make sure that you have read carefully the tomcat datasource documentation. My environment is J2sdk 1.4.1_01 <= 1.4 Tomcat 4.1.18 Apache 2.0.44 Tomcat Connector 2.0.3 Red Hat Linux 7.2 (prod) Windows 2000 (dev) Oracle 8.1.7 classes12.jar <= 1.2 1. Below is part of my context. Do not invent the resource type, driver, and factory. I saw someone use a different factory or driver think they are going to utilize Oracle's pooling. It is smart but it is wrong in this case. To prove it is wrong, read Tomcat source code. <Resource name="jdbc/abcd" auth="Container" type="javax.sql.DataSource"/> <ResourceParams name="jdbc/abcd"> <parameter> <name>driverClassName</name> <value>oracle.jdbc.driver.OracleDriver</value> </parameter> <parameter> <name>url</name> <value>jdbc:oracle:thin:@oratest.int.abcd.com:1521:PROD</value> </parameter> 2. Also in my app's web.xml <resource-ref> <description>Oracle Datasource</description> <res-ref-name>jdbc/abcd</res-ref-name> <res-type>javax.sql.DataSource</res-type> <res-auth>Container</res-auth> </resource-ref> Do not put commons-dbcp and pooling jars in your app's WEB-INF/lib, use Tomcat's (in common/lib). 3. Initialize the connection pool and get connection: Context initContext = new InitialContext(); Context envContext = (Context) initContext.lookup("java:comp/env"); DataSource dataSource = (DataSource) envContext.lookup("jdbc/abcd"); dataSource.getConnection() Don't do anything other than point 3 to get the connection or driver. I have had two problems before: - null driver: renamed classes12.zip to classes12.jar and put it ONLY in commons/lib. - cannot connect: use a real url other than Microsoft's name, so oratest won't work on linux while oratest.mydomain.com works. - cast exception: use commons dbcp and pooling in commons/lib.
