A Creating Deployment-Specific Pages
Oracle Single Sign-On provides a framework for integrating deployment-specific login, change password, and single sign-off pages with the single sign-on server. This means that you can tailor these pages to your UI look and feel and globalization requirements.
Oracle recommends that you use JavaServer (JSP) pages. Other Web technologies may provide inconsistent results. PLSQL pages are not supported. Sample pages are provided with the product. The Oracle Single Sign-On product ships with sample pages that are designed for testing with the Oracle Application Server.
