Yes the classes.jar file is in %CATALINA_HOME/common/lib
Here is snippet of code, disregard the list bindings call (debug statement
which prints out the binding)
Context initCtx = new InitialContext();
Context envCtx = (Context) initCtx.lookup("java:comp/env");
NamingEnumeration enum = initCtx.listBindings("java:comp/env/jdbc");
while (enum.hasMoreElements()) {
writer.print("Binding : ");
writer.println(enum.nextElement().toString());
}
DataSource ds = (DataSource) envCtx.lookup("jdbc/prod_d");
Connection conn = ds.getConnection();
Thanks,
Jeremy

No need to change the policy file.
Make sure the oracle drivers are in the correct directory ...
$TOMCAT_HOME/common/lib
and that the classes.zip file has been renamed to classes.jar
Also, maybe mail a sniplet of the code you use to do your lookup: Maybe
we can see something funny.
