Accessing the Ro Application

If the Ro application is deployed, then applications deployed on Converged Application Server can obtain an instance of the application from the Diameter node (com.bea.wcp.diameter.Node class). Example 4-2 shows the sample Servlet code used to obtain the Diameter Node and access the Ro application.

Example 4-2 Accessing the Ro Application

private RoApplication roApp;
void init(ServletConfig conf) {
  ServletContext ctx = conf.getServletContext();
  Node node = (Node) ctx.getParameter("com.bea.wcp.diameter.Node");
  roApp = node.getApplication(Charging.RO_APPLICATION_ID);
}

This code example would make RoApplication available to the Servlet as an instance variable. The instance of RoApplication is safe for use by multiple concurrent threads.
