Java Development Tools

I want to add a servlet to my ADF app. I already created it and adeded the servlet and servlet-mapping in web.xml

I wantto get a connection from my Data Source, i created it in the EMbebed OC4J Server preferences. Its the one my adf app uses and it works.

My code:

InitialContext ic = new InitialContext(); // JNDI initial context
DataSource ds = (DataSource) ic.lookup("jdbc/OracleDS"); // JNDI lookup

the name of the ds is jdbc/OracleDS

but i get the following error:
