It looks like your Oracle JSP compiler uses old version of sevlet API.(2.0)
 I believe the old version of that method was: session.putValue("user",
user);
insted of:
>           session.setAttribute("user", user);
and
session.setMaxInactiveInterval(900);
wasn't introduced yet.

I don't know what servlet engine, you are using but in order to run this
code you need Servlet API Version 2.2  (even 2.1 could be fine, but not
sure),  download (or JDeveloper 3.2 has one) new version of servlet.jar and
put it in lib directory of your tool.
