what is the difference between context.xml of Tomcat and server.xml of Tomcat ? If I want to add a tag like :
<Resource name="jdbc/MyDs" auth="Container" type="javax.sql.DataSource"
driverClassName="org.apache.derby.jdbc.ClientDriver"
url="jdbc:derby://localhost:1527/my_database;create=true"
username="me" password="me" maxActive="20" maxIdle="10" maxWait="-1" />
where should I add it ?
