Re: Tomcat Datasource -- please help..
Well, the way I do it is adding the data source using the admin tool, then adding a resource-ref to web.xml and a ResourceLink to the Context. This keeps things a bit cleaner in my opinion. What you're doing should work .. but I can't really give you much more than that. Try defining it through the admin tool and following the instructions for adding a resource-ref to web.xml and a ResourceLink to your Context.

Re: Tomcat Datasource -- please help..
Hi. I see a couple of things different from my working setup in your setup below. First: You need a tag as below just before the ResourceParams.../ResourceParams block: Resource name=jdbc/prototypedb auth=container type=javax.sql.DataSource/ Second, and this might not be a show stopper, change the driverClassName parameter in your ResourceParams/ResourceParams block to com.mysql.jdbc.Driver unless you really are using a version 2 mysql jar file. MySQL/J versions 3.0.x and up switched to com.mysql.jdbc.Driver as the primary JDBC driver. Third, and this isn't in your email, where is your mysql jar file? Ideally, it should be in common/lib with the dbcp jar file. If you've changed the location of the mysql jar file, you'll have to restart Tomcat. Otherwise reloading the app will probably be sufficient to make the changes live. --David Shilpa Nalgonda wrote: I have defined the resource in web.xml as below... and also defined the datasouce resources under context in server.xml... even then it does not help..
