Thanks for your quick feedback. So, according to the Servlet spec, I need to declare my resource needs in web.xml; then it's up to the container to provide those resources, and the spec says that is configured via <ResourceParams/> in the server's configuration? Or is that bit Tomcat specific as well?
I think the fact that I was using a GlobalNamingResource was clouding the issue; if I wanted this DataSource to be available only to this app, I could supply declaration in web.xml, and configuration in the <Context> OR both the resource declaration and configuration in the <Context> (but the latter would be non-portable). Is this correct? Thank you again. -Sasha On 10/13/03 17:24, "Aleksandr Shneyderman" <[EMAIL PROTECTED]> wrote: > > ResourceLink is the Tomcat's way of doing JNDI, so > if you port your app on some other server, the deployer > will not even know what is wrong if you do not have > that entry in your web.xml, because this is the only thing > that gets to be moved around (server.xml is not) > > Looks a bit redundant but it is there for protability. > I do not see any other reasons for it being there otherwise. > > Alex. > >> -----Original Message----- >> From: Sasha Borodin [mailto:[EMAIL PROTECTED] >> Sent: Monday, October 13, 2003 5:15 PM >> To: Tomcat Users List >> Subject: Declaring resources - web.xml vs. server.xml >> >> >> I've Googled and read the documentation without producing a definitive >> answer to this question: exactly what IS the purpose of declaring >> resources >> in web.xml? >> >> OK, I've got a GlobalNamingResource set up: >> >> <Resource auth="Container" name="jdbc/DataTrac" scope="Shareable" >> type="javax.sql.DataSource"/> >> >> <ResourceParams name="jdbc/DataTrac"> >> ...
