Chapter 5: JServ

---

Java is the platform independent, interactive programming language of the Web. Oracle 11i harnesses the power and flexibility of the Java language and Java extensions to allow the entire application to be served up as a thin client through a browser. It also harnesses the Java database capabilities along with the Java enabled front end to bring added features and added power to Oracle Applications.

JServ

JServ allows you to include Java servlets in the Oracle E-Business Suite application. It is a servlet engine that allows Apache to serve the nondatabase driven JSP to a requesting browser. Recall that the database driven JSP are delegated to the mod_ose module that is an Oracle provided module. JServ is an Apache standard module. Its functionality is available through the mod_jserv module plug-in. Requests for Java pages are routed through the mod_jserv module to Apache and from Apache through the module back to the requesting user.

While Apache is no longer offering new releases of the JServ product and is currently in maintenance mode (meaning that well tested patches could be released but not major updates), JServ remains a stable and useful tool. Providing complete environment independence, JServ is a server application that is responsible for serving requests made, translating the servlet requests, and forwarding them to the correct servlet engine.
