You need to place that code where ever you are creating your user session object. I don't know the architecture you are using so I really can't tell you exactly where to place it.

Here is what the documentation has on the subject:
<blockquote>
7.2.4.3.2 Web-to-Go User Context
Web-to-Go creates a user context (or user profile) for every user who logs in to Web-to-Go. Web applications always run within the user's specific context. Servlets, which are always part of an application, can use the user context (in which it is running) to access the services provided by Web-to-Go. The user context can then be used to obtain the following information.
Name of the user
Mode the user is running in (online or offline)
Application that a user is accessing
The database connection
Roles that the user has for this application
Name or value pairs stored in the registry for the user
Servlets can access the user profile through the standard named java.security.Principal obtained through the getUserPrincipal method of the javax.servlet.http.HttpServletRequest class.
This object can also be obtained from the HttpSession object. For example,
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException{
// Retrieve the database connection from the User Profile,
// which can be accessed from the HttpRequest
HttpSession session = request.getSession(true);
OraUserProfile profile = (OraUserProfile)session.getAttribute("x-mobileserver-user");     
7.2.4.3.3 Database Connectivity in Java Code
Servlets can obtain a connection to the Oracle database, using the following statement.
HttpSession sess = request.getSession();
WTGUser user = (WTGUser)sess.getAttribute("x-mobileserver-user");
Connection conn = user.getConnection() ;
