When is the tag I added in context.xml gets read?
===

In the `context.xml` of `Tomcat` I added the following tag :

    	<Resource name="jdbc/MyDatasource" 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" />

When does the following tag gets read ? Is it read when i start the server ?
