Hi Tom, what do you mean by "oracle.jar", where did you get that from ??
To put things simply, Oracle JDBC drivers are distributed in a file named
"classes12.jar" also available in ZIP format (classes12.zip).
Note that with TOmcat though, putting the ZIP file in common/lib won't
work cos Tomcat doesn't seem to load ZIP archives in common/lib. So, you
just have to drop the JAR version (classes12.jar) insie common/lib, and
you should be ok.
And while I might be wrong, I also wouldn't think that your problem is
related in any way to Eclipse itself, whatever version you use.

correct datasource configuration. I was configurating Tomcat 5.5

this is not the case for you.
Secondly, how you are you including the datasource configuration in
sever.xml file? I had this problem because, context.xml from
WebContents/META-INF was not included properly in the server.xml. Open
your sever.xml (located at
< worksapce\.metadata\.plugins\org.eclipse.wst.server.core\tmp 0\conf
directory in my case) and check if you have your Resource element
included properly. Pay attention to the driverClassName and url
attribute. Remember they were elements in 4.x and attributes in 5.x
Hope this solve your problem.

Raj

Hello Laurent,
I use the ojdbc14.jar for Oracle 10g.
This file worked before.
It is thus a jar, not a ZIP.
It could have been a possible error, of course.
thanks,
Tom

Did you check that your changes are not overwritten?

I am not sure about 5.0.xx. Old style Resource mapping did not work for
me in 5.5.

I feel (I am not sure though) server.xml get overwritten when you
publish your project. You can verify this. I have this configuration
working for me.

You dont need to put your JDBC drivers in your WEB-INF/lib directory. It
is better to put the in common directory ($TOMCAT_HOME/common/lib) as it
can be shared among web applications.

Hi Tom,
The main advantage of using a META-INF/context.xml is that it won't
disappear if you remove the Web project from the server.
The server.xml you see under the Servers project isn't the one used when
the Tomcat server is run. A copy is made under a "tmp" subdirectory of
".metadata\.plugins\org.eclipse.wst.server.core" which the running
Tomcat uses. This copy is made during the publish operation. If the
Web project contains a META-INF/context.xml, the child elements in that
file are included in the Context element in the "published" server.xml.
This achieves the same thing as your hand editing of the server.xml,
without the risk of loss. The META-INF/context.xml can also have the
same effect if you create a war file from the project and deploy it to a
"production" Tomcat server.
Cheers,
Larry
