In this configuration, the firewall is installed before the Session and Entity Bean as seen from the EJB clients.

The figure below shows this configuration.

Figure 3-2 Example configuration providing access to Session and Entity Bean via a firewall

For other examples, see 3.2 System configurations, in the uCosminexus Application Server System Design Guide.

Features

Because access to the Session and Entity Bean goes through the firewall, this system prevents unauthorized third party access to the system, leakage of information handled by applications, and illegal operation by third parties.

Access from the clients

Access to the Session and Entity Bean from all EJB clients goes through the firewall.

When using the firewall, the necessary software and processes to be activated on the application server machine and client machine are the same as those for system configurations that use Session and Entity Bean as access points. See 3.4.3 System configuration with Session and Entity Bean serving as access points, in the uCosminexus Application Server System Design Guide.
