I think that the context is ok bacause the log file (catalina.out) tells me:
[DEBUG] InitialContext = javax.naming.InitialContext@46110f9b
[DEBUG] lookup java:comp/env = org.apache.naming.NamingContext@3700f9b
[DEBUG] Datasource = Resource reference to a factory for java.sql.Connection
instances that may be used for talking to a particular
database that is configured in the server.xml file.
So ds isn't empty: the exception is thrown when I call:
Connection con = ds.getConnection();
The Datasource is Tomcat's Datasource ( I have followed jndi tutorial)
