Declaring resources - web.xml vs. server.xml 2003-10-13 - By Sasha Borodin
Back
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">
... All of my parameters ...
</ResourceParams>
Then I've got a ResourceLink in my Context definition:
<ResourceLink global="jdbc/DataTrac" name="jdbc/DataTrac"
type="javax.sql.DataSource "/>
-- ---- ---- ---
Now, Tomcat documentation states that I also need the following in my
web.xml file:
<resource-ref>
<res-ref-name>jdbc/DataTrac</res-ref-name>
<res-type>javax.sql.DataSource </res-type>
<res-auth>Container</res-auth>
</resource-ref>
Why??? Everything works WITHOUT this entry. And everything works WITH it
as well. So my question, again, is what is the purpose of declaring
resources in web.xml - to (for some reason) complement the resource
definitions in server.xml, to replace them, or what?
Thank you for your help.
