The image nlspg036.txt shows the components of the Oracle Globalization Development Kit. The client-tier browser sends requests to the middle-tier application, which sends the requests to the database in the server tier. The database returns a response to the middle-tier application, which sends the response to the browser.
User applications run on the J2EE container of Oracle Application Server in the middle tier. The J2EE application uses the GDK framework to simplify coding for globalization. Both the GDK framework and the application call the GDK Java API to perform locale-sensitive tasks. The J2EE container retrieves information from the LDAP server.
