Deployment of a firewall for servlets and JSPs

The following is an example of a system configuration that provides access to a servlet and JSP via a firewall.

Organization of this subsection: (1) System configuration features; (2) Machine software required and processes to be activated

(1) System configuration features

In this configuration, the firewall is installed before the servlet and JSP as seen from the Web clients.

The figure below shows this configuration. Note that this configuration is for Web server integration.

Figure 3-1 Example configuration providing access to a servlet and JSP via a firewall

[Figure]

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

Features: Because access to the servlet and JSP 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 servlet and JSP from all the clients goes through the firewall.

(2) Machine software required and processes to be activated

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 servlets and JSPs as access points. See 3.3.1 Deployment of reverse proxies for Web server integration or 3.3.2 Deployment of reverse proxies for using an in-process HTTP server.
