Ok guys, here we are. I have define the new resource inside a Context tag

wrap it in %% markers to indicate it's raw java code, not

Your JSP can't find one of the classes you refer to in the scriptlet.

We can't tell which one, because we don't know what's at line 266 in the

Which of the classes you're using in the JSP haven't

You are seriously confused,
For test purposes, i have wrote the following code as a java program and it
worked fine, but when I tried it in a jsp page i got the following error:

Logs should go to catalina.out, or to the console if you're using

Ok thank you, I did the following as you have stated:

Resource name=jdbc/TestMySql auth=Container type=javax.sql.DataSource
maxActive=100 maxIdle=30 maxWait=1

com.mysql.jdbc.Driver
Try this variant of your code:
Context initContext = new InitialContext();
DataSource ds =
(DataSource)initContext.lookup(java:comp/env/jdbc/TestMySql);
Connection conn = ds.getConnection();
out.println(Connection Established);
Essentially when you lookup java:comp/env/jdbc/TestMySql,

I've never dealt with Oracle but have done a lot of MySQL installs
without a single failure. Your config outside of the web.xml doesn't
look wrong in any way.
You might want to put the resource-ref block in your web.xml as
described in the how-to's. It doesn't hurt and is part of the

A few things to consider:
1. Either place your Resource definition in server.xml as a

2. If you have the Resource defined in the GlobalResources, that's the

You only need one resource definition.
You only need a resource link definition if your resource is a global one.
Simplify your configuration and then post the error message from the
logs so we can see Tomcat says is wrong.
