I am having problems geting a connection form a registered oracle datasource. I am confident that the datasouce is configured properly since I can see it on the :8082 admin page, and no exceptions are thrown when casting the lookup to a Datasouce object, below is the code i have and the exception that is throws. please help!

try {
InitialContext jndiContext = new InitialContext();
DataSource ds = (DataSource) jndiContext.lookup("java:/OracleDS");

if(ds==null){
System.out.println("ds is NULL");
}else{
System.out.println("ds NOT NULL");
}
System.out.println("looked up OracleDS");
con=ds.getConnection();
System.out.println("I got here");
} catch (NamingException e) {
System.err.println(e.toString());
return 0;
} catch (SQLException e) {
System.err.println(e.toString());
return 0;
}
