Ok guys, here we are. I have define the new resource inside a <Context> tag
inside a <Host> tag, as suggested by Tomcat documentation. I removed it and
put it inside <GlobalNamingResources> tag like the following:
1. Configure naming Resource:
inside <GlobalNamingResources> i put the following:
<Resource name="jdbc/DBTest" auth="Container" type="javax.sql.DataSource"
maxActive="100" maxIdle="30" maxWait="10000"
username="root" password="exam" driverClassName="
com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost:3306/exam"/>
2. Inside web.xml:
<resource-ref>
<description>Oracle Datasource example</description>
<res-ref-name>jdbc/DBTest</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
3. Finally, you have to connect your server to the new resource. To do that,
inside context.xml put the following:
<ResourceLink global="jdbc/DBTest" name="jdbc/DBTest" type="
javax.sql.DataSource"/>
4. Test your code as follow:
<%@ page import = "java.sql.*, javax.naming.*, javax.sql.*" %>
<%
Context initContext = new InitialContext();
DataSource ds =
(DataSource)initContext.lookup("java:comp/env/jdbc/DBTest");
Connection conn = ds.getConnection();
out.println("Connection Established");
%>
Tomcat 6 documentation stated that you have to put naming resource
definition inside the Context tag. And this was the problem, when i removed
it from their it worked find and the connection established successfully.
Anyways, thank you very much buddies for your time and consideration. I am
always saying that the user of this mailing list are the best developers in
the world. ;)
