the only thing might be that you can leave out tracks_adm from <value>jdbc:oracle:thin:[EMAIL PROTECTED]:1521:paso2d</value>
And if you do the lookup though:
Context ctx = new InitialContext();
Object datasource = ctx.lookup("java:/comp/env/jdbc/paso2d");
?

ps and part of your server.xml was missing, but i assume you didn't paste all of it (the closing tags etc)

Hi, there are 4 parts to this, a pool definition in your server.xml a resource ref in your web.xml a snippet of java code to get the datasource. a bunch of drivers (probably something like classes12.jar)
Did you specify the first three of them and included the last one?
