Thank you Pid for your patience with me, Thank you all guys, the problem finally sovled, and the connection established.
The problem was because of i didn't state the <ResourceLink>, I put it like this: <ResourceLink name="jdbc/myoracle" type="javax.sql.DataSource" global="jdbc/myoracle"/> in Context.xml, and i removed all occurences of jdbc class drivers but in CATALINA_HOME/lib. By the way, it is the advice of David Smith and Pid. Thank you guys, Thank you ver much :). Jotnarta On 5/26/07, Pid <[EMAIL PROTECTED]> wrote:

Which is best, servlet.xml or context.xml? You must add information to all of config files, it's not optional, I think the documentation is pretty clear on what needs to be added to each file.

I'm not aware of a Tomcat configuration file called "servlet.xml". Tomcat uses the following files (in addition to your web app's files): <tomcat>/conf/server.xml - main config <tomcat>/conf/context.xml - default/all contexts <tomcat>/conf/web.xml - main config You can configure the Context by placing the definition in - EITHER: <tomcat>/conf/<hostname>/<contextname>.xml OR: <webapp>/META-INF/context.xml You should also configure your servlet definitions and the remainder of your application as per the spec in: <webapp>/WEB-INF/web.xml > 3.

You can place the oracle jar file in - EITHER: <tomcat>/lib OR: <webapp>/WEB-INF/lib > I susbect with jdbc driver, if you look at otn.oracle, you will find many > drivers for all jdks, but there is no one for JDK 6. It's not the driver, it's your config. Tomcat+Oracle is successfully deployed by many people all over the world. So, in summary, as an *example* to demonstrate some possible locations for various bits of config, you might have: Resource def in GlobalResources, 'testhost' Host def: /path/to/tomcat6/conf/server.xml ResourceLink in Context: /path/to/tomcat6/conf/testhost/ROOT.xml oracle-XXX.jar in /path/to/tomcat6/lib Resource ref, servlets in: /path/to/testhost/webapps/ROOT/WEB-INF/web.xml JSP in: /path/to/testhost/webapps/ROOT/test.jsp p p.s. Chuck, if you read this, I'm betting that you'll need to get your path attribute standard response ready. > On 5/26/07, Pid <[EMAIL PROTECTED]> wrote: >> >> Mohammed Zabin wrote: >> > Thank you Christ >> >> For instance, I usually see "oracle.jdbc.driver.OracleDriver" instead >> of >> >> what you have above. >> > >> > It's as you stated above.
