n i have made settings like below:

And am getting error for below line:

DataSource ds = (DataSource)envContext.lookup("jdbc/myoracle");

Am i missing something....?

Thank you.........

回答1:

Your problem is that you need to prefix your jndi string with java:/comp/env

So in your case try:

DataSource ds = (DataSource)envContext.lookup("java:/comp/env/jdbc/myoracle");

That should solve the problem.

回答2:

I also come across with this problem, but in my case I've fixed by adding bellow line:

<ResourceLink global="jdbc/myoracle" name="jdbc/myoracle" type="oracle.jdbc.pool.OracleDataSource"/>

to tomcat conf file -> context.xml.

回答3:

Try just "java:"

(DataSource) context.lookup("java:jdbc/myoracle");
